The engine is the heart of the washing machine. This device rotates the drum during washing. In the first models of machines, belts were attached to the drum, which acted as drives and provided the movement of the container filled with laundry. Since then, the developers have significantly improved this unit, which is responsible for converting electricity into mechanical work.

Currently, three types of motors are used in the manufacture of washing equipment.

Kinds

Asynchronous

Motors of this type consist of two parts - a stationary element (stator), which serves as a supporting structure and serves as a magnetic circuit, and a rotating rotor, which drives the drum. The motor rotates as a result of the interaction of the alternating magnetic field of the stator and the rotor. This type of device was called asynchronous because it is not able to achieve the synchronous speed of a rotating magnetic field, but follows it, as if catching up.

Asynchronous motors are found in two versions: they can be two- and three-phase. Two-phase samples are rare today, since at the threshold of the third millennium their production practically ceased.

The weak point of such an engine is the weakening of the torque. Outwardly, this is manifested in a violation of the trajectory of the drum - it sways without making a full turn.

The undoubted advantages of asynchronous devices are the simplicity of the design and ease of maintenance, which consists in timely lubrication of the motor and replacement of failed bearings. The asynchronous motor works quietly, but it is quite cheap.

The disadvantages of the device include large size and low efficiency.

Usually these motors are equipped with simple and inexpensive models that do not differ in high power.

Collector

Collector motors have replaced two-phase asynchronous devices. Three quarters of household appliances are equipped with this type of motor. Their feature is the ability to operate on both AC and DC.

To understand the principle of operation of such an engine, we will briefly describe its structure. The collector is a copper drum divided into even rows (sections) by insulating “baffles”. The places of contacts of these sections with external electrical circuits (the term "leads" is used to designate such sections in electrics) are located diametrically, on opposite sides of the circle. Both brushes are in contact with the leads - sliding contacts that ensure the interaction of the rotor with the motor, one on each side. As soon as any section is powered, a magnetic field appears in the coil.

When the stator and rotor are turned on directly, the magnetic field begins to rotate the motor shaft clockwise. This is due to the interaction of charges: the same charges are repelled, different charges are attracted (for greater clarity, remember the "behavior" of ordinary magnets). The brushes gradually move from one section to another - and the movement continues. This process will not be interrupted as long as there is voltage in the network.

To turn the shaft counterclockwise, the charge distribution on the rotor must be changed. To do this, the brushes are turned on in the opposite direction - towards the stator. Usually, miniature electromagnetic starters (power relays) are used for this.

Among the advantages of a collector motor are high rotation speed, smooth change in speed, which depends on voltage changes, independence from the frequency of oscillations of the power grid, large starting torque and compactness of the device. Among its disadvantages, a relatively short service life is noted due to the rapid wear of the brushes and the collector. Friction causes a significant increase in temperature, as a result of which the layer that insulates the collector contacts is destroyed. For the same reason, an interturn short circuit can occur in the winding, which can cause a weakening of the magnetic field. An external manifestation of such a problem will be a complete stop of the drum.

Inverter (brushless)

An inverter motor is a direct drive motor. This invention is just over 10 years old. Developed by a well-known Korean concern, it quickly gained popularity due to its long service life, reliability, durability and its very modest dimensions.

The rotor and stator are also components of this type of motor, however, the fundamental difference is that the motor is directly attached to the drum, without the use of connecting elements that fail in the first place.

Among the undoubted advantages of inverter motors are simplicity, the absence of parts subject to rapid wear, convenient placement in the machine body, low noise and vibration levels, and compactness.

The disadvantage of such a motor is its labor intensity - its production requires a lot of costs and efforts, which is noticeably reflected in the price of inverter machines.

Connection diagram of the motor to the network

Modern washing machine

When connecting the engine of a modern washing device to a 220V network, it is necessary to take into account its main features:

• it works without a starting winding;
• the motor does not need a starting capacitor to start.

To start the engine, the wire leading from it must be connected to the network in a certain way. Below are the connection diagrams of the collector and brushless electric motors.

First of all, define the "scope of work" by excluding the contacts that come from the tachogenerator and do not participate in the connection. They are recognized by a tester operating in ohmmeter mode. After fixing the tool on one of the contacts, find the pin that is paired to it with the other probe. The resistance value of the tachogenerator wires is about 70 ohms. To find pairs of the remaining contacts, call them in the same way.

Now we pass to the most important stage of work. Connect the 220V wire to one of the winding outputs. Its second outlet needs to be connected to the first brush. The second brush connects to the remaining 220-volt wire. Plug in the motor to test its operation *. If you don't make any mistakes, the rotor will start to rotate. Keep in mind that when connected like this, it will only move in one direction. If the test run was completed without linings, the device is ready for operation.

To change the direction of movement of the motor to the opposite, the connection of the brushes should be reversed: now the first will be connected to the network, and the second is connected to the output of the winding. Check the readiness of the motor for operation as described above.

You can clearly see the connection process in the following video.

Old model washing machine

Connecting the engine in old-style cars is more complicated.

First, identify two matching lead pairs. To do this, use a tester (aka a multimeter). Having fixed the tool on one of the winding leads, find the lead paired to it with the other probe. The remaining contacts will automatically form a second pair.

Washing machines, over time, fail or become obsolete. Usually,
the basis of any washing machine is its electric motor, which can find its application and
after disassembling the washing machine for spare parts.

The power of such motors, as a rule, is not less than 200 W, and sometimes much more, the speed
shaft revolutions can reach up to 11,000 revolutions per minute, which may well be suitable for using such an engine for household or small industrial needs.

Here are just a few ideas for the successful use of an electric motor from a washing machine:

• Grinding ("emery") machine for sharpening knives and small household and garden tools. The engine is installed on a solid base, and a sharpening stone or an emery wheel is attached to the shaft.

• Vibrating table for the production of decorative tiles, paving slabs or other concrete products where it is necessary to compact the mortar and remove air bubbles from there. Or maybe you are engaged in the production of silicone molds, for this you also need a vibrating table.

• Vibrator for concrete shrinkage. Self-made designs of which are abundant on the Internet may well be implemented using a small motor from a washing machine.

• Concrete mixer. Such an engine is quite suitable for a small concrete mixer. After a small alteration, you can use the regular tank from the washing machine.

• Manual construction mixer. With this mixer, you can mix plaster mixes, tile glue, concrete.

• Lawn mower. An excellent option in terms of power and dimensions for a lawn mower on wheels. Any ready-made platform on 4 wheels with a motor fixed in the center with a direct drive to the "knives" which will be located underneath will do. The height of the lawn can be adjusted by seating, for example by raising or lowering the swivel wheels in relation to the main platform.

• Mill for grinding grass and hay or grain. Especially important for farmers and people involved in breeding poultry and other animals. You can also prepare feed for the winter.

There can be a lot of options for using an electric motor, the essence of the process is the ability to rotate various mechanisms and devices at high speeds. But no matter what mechanism you are going to design, you still need to wake up correctly
connect the engine to the washing machine.

Engine types

In washing machines of different generations and countries of production, there may be different types
electric motors. Typically, this is one of three options:

Asynchronous.
Basically, these are all three-phase motors, they can also be two-phase, but this is very rare.
Such motors are simple in their design and maintenance, basically it all comes down to lubricating the bearings. The disadvantage is the large weight and dimensions with low efficiency.
Such motors are found in old, low-power and inexpensive washing machines.

Collector.
Motors that have replaced large and heavy asynchronous devices.
Such an engine can operate on both AC and DC, in practice it will even rotate from a 12 volt car battery.
The motor can rotate in the direction we need, for this you just need to change the polarity of connecting the brushes to the stator windings.
High rotational speed, smooth speed change by changing the applied voltage, small size and high starting torque are just a few of the advantages of this type of motor.
The disadvantages include wear of the collector drum and brushes and increased heating during not so long-term operation. More frequent maintenance is also needed, such as cleaning the manifold and replacing the brushes.

Inverter (brushless)
An innovative type of motors with direct drive and small dimensions with a fairly high power and high efficiency.
The stator and rotor are still present in the motor design, but the number of connecting elements is kept to a minimum. Lack of elements subject to rapid wear, as well as low noise level.
Such motors are found in the latest models of washing machines and their production requires relatively more costs and efforts, which, of course, affects the price.

Connection diagrams

Motor type with starting winding (old / cheap washers)

First you need a tester or multimeter. You need to find two matching pairs of pins.
With the tester's probes, in the dialing or resistance mode, you need to find two wires that ring among themselves, the other two wires will automatically be a pair of the second winding.

Next, you need to find out where we have the starting winding, and where is the working winding. You need to measure their resistance: a higher resistance will indicate a starting winding (PO) which creates the initial torque. A lower resistance will indicate to us an excitation winding (OB), or in other words - a working winding that creates a magnetic field of rotation.

Instead of the "SB" contactor, there can be a low-capacity non-polar capacitor (about 2-4 μF)
How it is arranged in the washing machine itself for convenience.

If the engine starts without load, that is, does not wake up a pulley on its shaft with a load at the moment of starting, then such an engine can start itself, without a capacitor and short-term "powering" of the starting winding.

If the engine is overheating or it heats up even without load for a short time, then there may be several reasons. Perhaps the bearings are worn out or the gap between the stator and the rotor has decreased, as a result of which they touch each other. But most often the reason may be the high capacitance of the capacitor, it is not difficult to check - let the engine run with the starting capacitor disconnected and everything will become clear at once. If necessary, it is better to reduce the capacitance of the capacitor to the minimum at which it copes with the start of the electric motor.

In the button, the "SB" contact must strictly not be fixed, you can simply use the button from the doorbell, otherwise the starting winding may burn out.

At the moment of starting, the "SB" button is clamped until the shaft spins up to full (1-2 sec.), Then the button is released and the voltage is not applied to the starting winding. If reverse is necessary, you need to change the winding contacts.

Sometimes in such a motor there may be not four, but three wires at the output, in which case the two windings are already connected at the midpoint to each other, as shown in the diagram.
In any case, disassembling an old washing machine, you can take a closer look at how its engine was connected to it.

When the need arises implement reverse or change the direction of rotation of the motor with a starting winding, you can connect it as follows:

An interesting point. If the starting winding is not used (not used) in the motor, then the direction of rotation can be all possible (in either direction) and depend, for example, on which direction to turn the shaft at the moment when the voltage is connected.

Collector type of engine (modern, top-loading washing machines)

As a rule, these are collector motors without a starting winding, which do not need a starting capacitor either; such motors operate on both direct current and alternating current.

Such a motor can have about 5 - 8 leads on the terminal device, but we do not need them to operate the motor outside the washing machine. First of all, you need to exclude unnecessary tachometer contacts. The resistance of the tachometer windings is approximately 60 - 70 ohms.

Thermal protection leads can also be drawn, which are rare, but we also don’t need them, it is usually a normally closed or open contact with "zero" resistance.

Then we connect the voltage to one of the winding terminals. Its second output is connected to
the first brush. The second brush connects to the remaining 220-volt wire. The engine should run and rotate in one direction.

To change the direction of movement of the motor, the connection of the brushes must be reversed: now the first will be connected to the network, and the second is connected to the output of the winding.

Such an engine can be checked with a 12 volt car battery, without fear of "burning" it due to the fact that it was connected incorrectly, you can calmly
"experiment" with reverse and see how the engine operates at low speed from low voltage.

When connecting to a voltage of 220 volts, keep in mind that the engine will start abruptly with a jerk,
therefore, it is better to fix it motionless so that it does not damage or short-circuit the wires.

Speed ​​regulator

If it becomes necessary to regulate the number of revolutions, you can use
household dimmer () .But for this purpose, you need to select a dimmer that will have more power than the engine power, or you need some work, you can remove the triac with a radiator from the same washing machine and solder it in place of a low-power part in the dimmer design ... But here you already need to have skills in working with electronics.

If you manage to find a special dimmer for such electric motors, then it will be
the simplest solution. As a rule, they can be found at the points of sale of ventilation systems and they are used to adjust the speed of the engines of the supply and exhaust ventilation systems.

In most publications on the topic of designing a device with your own hands, it is advised not to purchase the necessary components and assemblies, but to use components that have served their time from various household appliances. The solution is perfectly reasonable. The most popular is the electric motor from an outdated or outdated washing machine.

According to their characteristics, such engines are suitable for the assembly of various technical devices. It is not difficult to dismantle them. But with the connection of such an electric motor to a 220-volt network, questions often arise. Let's analyze the options for the correct connection and use of different types of electric motors from washing machines.

How to connect an electric motor from a washing machine

Engine use

There are quite a few options for how you can use high-speed electric motor for a washing machine in the case when the washing machine has already served its purpose. The household always needs a device that can sharpen knives, scissors and other tools. You can make such a device yourself if you correctly connect the electric motor from the washing machine and securely attach a sharpening stone to it.

If you are engaged in construction or planning to work with concrete, then you can make a vibrator, which, using a motor from a washing machine, will help the concrete to shrink. There are craftsmen who have adapted an electric motor to create a vibrating table, and with its help they make paving slabs or cinder blocks at home. And also the motor from an old washing machine will find application for itself and for various agricultural purposes. This can be, for example, a fresh herb grinder or a cereal grinder. It will be possible to procure good feed for poultry, you can also make preparations for animals for the winter, and process weeds.

It can be concluded that range of application the electric motor is very diverse, most importantly, it is possible to rotate various attachments. You can also activate some designed devices and mechanisms. In any case, you need to know how to connect a motor from a washing machine to an automatic machine.

Collector motor

Now the industry produces a very large number of different brands and modifications of washing machines. The motors of these machines also have a different design; a different number of wires can depart from them. Accordingly, the circuits for connecting the electric motors of these machines to the 220 volt network may differ.

Consider the wires from the collector motor. All the wires coming out of the engine have different colors and terminated at a terminal block or connector. The first on the terminal block (left) are two white wires. These wires are needed to connect the tachometer so that the speed of the electric motor can be measured. In our case, we will not use them.

For control, you can measure the resistance of the loop of these wires with a multimeter. It should be 70 ohms. Next, let's decide on the stator winding. On the terminal block, after the white wires, there should be a wire in red insulation, and then in brown. These should be the stator wires. And also to eliminate the error, we will ring them with a multimeter. Resistance should be close to zero. The remaining two wires, usually gray (blue) and green, go to the motor brushes.

In order to connect such engine to the network ~ 220 volts it should be remembered that engines of this type are used without the use of a starting capacitor. By installing a jumper between one of the stator wires and the wire coming from the brush, the mains voltage is applied to the other pair of wires. The motor should start spinning. In order to change the direction of rotation of the electric motor, it is enough to switch the jumper to another brush.

Asynchronous motor

• Option 1

How to start the engine from an old type washing machine? Motors of this type are somewhat more difficult to connect. If you decide to connect a motor for this type of washing machine, then you will definitely need a multimeter. Motors of this type have two windings. One of the windings is working, the other is starting.

Initially, you need to determine these windings, that is, you need to determine the pairs of wires that are ringing among themselves. This work is done with a multimeter in dial mode. Further, with a multimeter in the resistance measurement mode, you need to determine the resistance of the windings and write down the result on paper. The winding with the lower resistance is the working winding.

To connect such a motor, you need a momentary button or starting relay... For an error-free connection, it is advisable that you have a diagram of how to connect a motor from an old-type washing machine. Connecting a motor from a washing machine to 220 can be described as follows. A voltage of ~ 220 volts is applied to the working winding of the motor. The same voltage is also applied to the starting winding, only through the start button or relay for a short period of time. After the engine starts to rotate, the button must be released. In order for the motor to start rotating in the other direction (reverse), the phasing of the applied voltage must be reversed.

• Option 2

Previously, there was another type of engine. Outwardly, they do not differ from motors with two windings. These models had a power of 100-120 watts and a rotational speed of 2700-2850 rpm. and were used in the centrifuge drive. Such motors had a so-called working capacitor, that is, it was constantly on. Due to the fact that the centrifuge did not need to change the direction of rotation, the connection of the windings was made inside the motor housing, and only three wires came out of it, often of the same color.

The winding resistance of such motors was the same. This type of motors is connected according to the following scheme. One of the terminals and the midpoint of the windings are turned on to the 220 volt network, the other output through a capacitor is connected to the first output.

When you make any device from a washing machine engine, be sure to pay attention to the serviceability and prevention of this device during operation. Major motor failures are due to overloading or bearing wear. Therefore, you need to pay attention to all the nuances of the device in a timely manner.

But in this world, nothing is eternal. Washing machines also deteriorate and need to be replaced. But in some families there are self-made men. They will not take such an interesting thing as a washing machine to the landfill on the day of the breakdown, but will take it apart and leave the most interesting details in their men's household. And there are many interesting things in the car. The most important thing is the electric motor. It’s worth talking about it in more detail. How to connect the washing machine motor to the network - we'll talk about this in this article.

Every ordinary user is not at all obliged to understand well the electrical circuit of the washing machine. This is necessary for those who are engaged in the repair of this representative of complex household appliances. But a general idea of ​​its structure will not hurt anyone.

PHOTO: 1stiralnaya.ru

Any washing machine consists of a mechanical and an electrical part. Mechanics include the body, door, drum, all bearings and gears. Springs are installed to cushion the machine from shaking during spinning. Water is supplied to and drained from the machine through hoses, which are fixed in branch pipes with seals. In the drainage system, a drain pump is installed at the outlet. A three-section tray is built into the machine for loading detergents.

The electrical part includes an electric motor, an electrical circuit for its switching on, a drain pump motor, a set of devices that form an algorithm and the safety of the washing process.

The electrical circuit of the washing machine is primarily designed to turn on the motor.

The electric motor and drum are parts that easily pass into another life. Especially the motor. There are models equipped with two electric motors: one is the main one for washing, with a rotation speed of about 2000 rpm, and the second is a high-speed one for a spin centrifuge, with a rotation speed of about 3000 rpm.

The control system implements the washing program chosen by the hostess. In old cars they are based on time relays, in modern cars they are electronic systems. A certain time is allocated for each operation of the program, a command is formed to turn on the engine in one direction or another. Some models have a third electric motor that drives the programming cam.

The control circuit monitors the temperature of the motor windings in order to protect it from overload. Level and pressure sensors provide information to control the water supply. The heating of the liquid for washing also occurs in the machine itself. A temperature regulator (thermostat), which works in conjunction with a temperature sensor, turns electrical heaters on and off. If the engine is in a machine with variable speed, then a speed sensor (tachogenerator) is provided in the control system.

The owner sets his wishes to the car from the control panel located in the upper front of the car body.

For the safety of the user, all machines are equipped with a locking system. It prevents the motor from starting when the loading door is open and the door from opening when there is water in the machine. A non-return valve on the water supply pipe protects against flooding.

The washing machine is connected to the mains with a three-pole earthed plug.

What you need to consider when connecting motors from a washing machine of different types

The washing machine is connected to the electrical network in accordance with "PUE 7. Rules for Electrical Installations".

Even a superficial acquaintance with the device of the machine and its electrical circuit provide a more conscious operation and the ability to minimize the number of emergency situations. A schematic diagram is a graphical representation of the main electrical components of a machine and the connections between them.

There are three types of electric motors used in washing machines.

Asynchronous

In most washing machines of previous years, three-phase asynchronous motors are used, each of which consists of a stationary stator and a rotating rotor. The alternating current initiates a rotating magnetic field in the stator winding sections, which induces a current in the rotor. This secondary induced current interacts with the magnetic field of the stator, and a force that rotates it begins to act on the rotor, due to which it begins to rotate and transfer its rotation to the devices associated with it.

Engines of this type are simple in design, unpretentious in maintenance, and reliable in operation. The main disadvantages are large inrush currents and difficulties in controlling the rotation speed.

Collector

In collector motors, the windings are located on both the stator and the rotor. The current is supplied to the rotor through a device called a "collector", which consists of lamellas fixed on the rotor shaft, and two "brushes" stationary relative to the stator.

PHOTO: elektt.blogspot.com

The collector motor operates on both AC and DC power. Here it is easy to regulate the speed by changing the value of the supply voltage. As an industrial device, you can use a dimmer of a suitable power from the lighting system.

Inverter

The inverter motor in the washing machine is the most modern solution. The principle of operation is that in the built-in inverter, the alternating current of the electrical network is converted into direct current, and then again into alternating current of the required frequency, which determines the speed of rotation of the shaft. He, in contrast to the collector, has no brushes and makes less noise. No brushes - no wearing parts, so nothing needs to be replaced regularly. But you have to pay for the inverter, such a machine is more expensive.

Differences between electric motors

The differences between the types of electric motors are given in their descriptions. The asynchronous motor is the simplest in design. The collector has the ability to easily adjust the rotation speed. And the inverter motor is directly connected without belts and gears to the drum shaft. In short, more modern motors are less noisy, subject to speed control, but are more expensive.

Connecting the engine of a modern washing machine to the 220 V network

Washing machine motor connection diagram

New washing machines have “automatic” main engine of collector type. This means that it has a double-coil winding on the stator and an excitation winding on the rotor. The rotor and stator are connected in series. The current enters the field winding through the brushes. The wiring diagram for connecting the motor to the mains is the same as on No. 5.

Speed ​​regulator

The speed controller can be used with any standard power of 2.5–3.0 kW. You can also use a lighting dimmer, but in it you first need to replace the triac with a BT138X-600 or BTA20-600BW or another model with ten times the motor current consumption.

To avoid a drop in speed under load, special devices are used on an integrated circuit TDA1085, which control the current and voltage on the motor.

If the engine speed needs to be reduced significantly, then it should be connected to the load through a belt drive or gearbox.

How to connect a motor to a washing machine

When connecting a motor removed from the washing machine, it is necessary to remove the excess wires. When working, you should be guided by Figures 7 and 8, carefully controlling the color of the wires.

Connecting the motor of an old washing machine

Old washing machines have asynchronous motors with two windings - starting and working. The starting winding has a higher ohmic resistance. If output wires from both windings are found, and both windings are intact, then the motor can be connected

Wiring diagram of the motor from the washing machine

There are two options for connecting the motor - with a capacitor designed for a voltage of 450-600 V, with a capacity of 4 to 8 μF and with a short-term start button.

How to connect the motor

To connect the motor, the first step is to determine the pairs of wires from both windings. After that, decide on the connection scheme - with a capacitor or with a button. Assemble the circuit and perform a test switch. If the engine turns in the wrong direction, which is needed by the owner, then the connection points of the starting winding should be reversed.

The electric motor is often called almost the heart, which is installed in household appliances. And this is not in vain, because it is thanks to the electric motor that the drum installed in the washing machine rotates. Many people doubt whether it is possible to connect the engine from the washing machine to another device with your own hands?

Electric motor from a broken washing machine

What can be done with the washer engine

It is quite possible to fulfill this, even if you practically do not understand such issues. For example, your Indesit washing machine is out of order, while the engine (its power is 430 W, and the developing speed reaches 11,500 rpm) is still in working order, and its motor resource is still normal. In this case, it can come in handy on the farm.

Here are some ideas to help you apply or connect a new motor installed in a washing machine that is out of order:

1. An elementary option would be to create a grinding machine. In every house, knives and scissors that need to be sharpened are periodically grinded and blunt. To do this, it is necessary to carefully fix the electric motor on a stable surface, attach a special sharpening stone or a grinding wheel to the shaft and turn it on.
2. A good option is the manufacture of paving slabs. You can also make cinder blocks, and if there is a private sector, then a great idea is a vibrating table.
3. For villagers who are engaged in raising birds, you can construct a grinder and a grass mill from a washing machine engine.

Features of the motor are the key to successful work

Today there are more than enough different options for how you can give new life to an old motor from a washing machine, if it is still running. And all these ideas are based on the peculiarities of the motor to rotate various attachments or to provide the movement of additional mechanisms. You can come up with an even more original version of using the removed engine, but in order to bring your idea to life, you need to understand exactly how the motor is connected from the washing machine.

When connecting the engine that was left over from your old washing machine to another device, you need to keep in mind several important nuances of this process:

• motors are not connected with a capacitor;
  no starting winding required.

The transfer case contains wires of various colors, which you just need to deal with:

• 2 white wires - when connected, they will not be useful, since they are responsible for ensuring that the tachogenerator works normally;
• red and brown are intended so that it is possible to wind the stator, as well as the rotor;
• green and gray - for connecting to special brushes made of graphite (most often the same can be said about the brushes of the motor of the Indesit washing machine, in the event that they need to be replaced).

Correct connection of wires is the key to the successful operation of the motor

Please note that different motor models may have different colors of wires, but the principle of their connection is the same in all cases. To detect pairs, it is necessary to ring the wires in turn (those that are intended for the tachogenerator must have a resistance of 60 to 70 ohms). It is better to glue these wires with electrical tape away from others so as not to get confused. The remaining wires also need to ring to identify pairs.

As you can find out in our article.

Connection diagram

To continue working, you need to carefully study all the nuances of the electrical connection diagram. Basically, it was made in great detail and is understandable even for the home craftsman, who is the most distant from the world of electrical engineering.

Connecting the engine from the washer

Connecting or replacing a washing machine motor is actually quite simple. First of all, it is necessary to prepare the wires that will be used for the rotor, as well as for the stator. Make a special jumper that should be limited with electrical tape. Those two wires that remain are connected directly to the network.

Remember! When you connect the motor that remained from the old washing machine to 220, the device immediately begins to actively rotate. Therefore, before starting work, make sure that the motor is firmly on one surface or another.

Connection diagram of the old engine to the 220 network

If it is necessary to change the direction of rotation, it will be enough that you put a jumper on the contacts that remain. To turn the device on and off, it is necessary to connect special buttons to the circuit. In order to do this, you need to use the appropriate schemes, which can easily be found on special sites.

Now we know exactly how to connect the motor so that it can still be used for a long time. How can you improve the resulting device?

Speed ​​control

For proper operation, you need a speed controller

The washing machine motor is characterized by a fairly high rotation speed, so it is advisable to make a special regulator so that the hammer motor works in different speed modes without overheating. For this purpose, you can use a conventional light intensity relay, but slightly modified.

It is necessary to remove the triac from the "washing machine" together with the radiator - the so-called semiconductor device (in the control of electrons, it functions as a controlled switch).
Then it is necessary to solder this device into the relay microcircuit, replacing the parts with low power. If you do not know all the nuances of this procedure, it is better to ask the help of a specialist (electronics or computer technician).

There are times when the engine does a new job without the aid of the governor.

Engine types

Varieties of engines from washers

Asynchronous. It can be removed only together with the condenser, which are completely different for each model of the washing machine. It is not recommended to break the connection of such a motor with a battery if its case is sealed and formed of various metal or plastic.

Attention! The asynchronous motor should only be removed from the washing machine when the capacitor is completely discharged, since this can avoid electric shock.

Asynchronous motor

Low-voltage motor of the collector type. It is characterized by the presence of regular magnets on the stator, which are alternately connected to a constant voltage current. On the body of such a motor there is a sticker on which the figure for the maximum allowable voltage is placed.
Electronic engine. This type of device must be disconnected only together with the electronic power supply unit (ECU); a sticker with the value of the maximum allowable connection voltage is placed on its body. Pay attention to the polarity, because motors with this operating principle do not have the desired reverse.

Frequent breakdowns: what you can face

How to connect an electric motor from an old washing machine is now known. But there are situations when the motor does not start. What are the reasons and solutions to such a nuisance?

Try to check the state of heating of the motor after three minutes of operation. In such a short time, all parts cannot heat up equally, so you have the opportunity to identify the fault location that will be too hot. This can be a bearing assembly, a stator, etc.

Various engine malfunctions

The main reasons why a particular part is too hot may be the following:

• clogged or failed bearing;
• overly expanded capacitance.

Correct engine connection

For the correct connection of the motor, which was left from the old washing machine, a minimum amount of knowledge and a little effort is enough. Also for this purpose, a winding using a multimer is used. To locate the required wires, it is required to ring the winding. This will allow you to select the correct pairs for connection. Everything is done very simply. The multimeter is connected to one wire, and the other end of the device should be touched in turn to the other wires in order to find the desired pair. It is also worth fixing in advance what the value of the winding resistance is. This information will be useful in the future. After the end of the ringing procedure, you should have 2 windings that would have different resistance values.

These windings are divided into two completely different types. One has an indicator of working resistance. The second type of winding is one of the starting parts. It is known that the value of the resistance of the working winding should be less than the starting one. In order for the motor from the washing machine to work fully, you need to use either a button or a special starting relay. As a button, you can even take the one that is installed for the doorbell. The main thing is that she does not have a fixed contact.

New life of an old motor - use for other purposes

The process of connecting the engine, which was left from the old washing machine, is incredibly simple and easy. It is enough to find a correct and useful application for it. Then he will be able to serve you for a while. You can experiment and make some really useful equipment that will make your life easier in other areas. A little imagination and skill is enough to make everything work out.
