Connect the electric motor from the old washing machine. How to connect a washing machine motor. Frequent breakdowns: what you can face

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 washing machine... 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 the software. new engine installed in a washing machine that is out of order:

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 stone to the shaft for sharpening or grinding wheel and plug it into the network.
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.
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 washing machine if it is still starting. 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 engine 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.

On transfer case there are 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 be aware that different models motors can have wires of different colors, 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 electrical circuit connections. 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! Asynchronous motor remove from the washing machine only when the capacitor is completely discharged, as 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 Electrical engine 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.

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. Great 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 applications for an electric motor, the essence of the process is the ability to rotate on high revs different mechanisms and devices. 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 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 level noise.
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 the 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 start-up, 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 that 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 do not need them, this 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 car battery at 12 volts, without being afraid to "burn" it due to the fact that it was connected incorrectly, you can calmly and
"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 most simple 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.

Hello everyone! Washing machines often fail and are thrown into landfills. But some of the machine parts and parts can still serve and bring a lot of benefits. A classic example is emery and a washing machine.
Today I will tell and show you how to properly connect an electric motor from a modern washing machine to the network alternating current voltage of 220 V.
I would like to say right away that such motors do not need a starting capacitor. Just the right connection is enough and the engine will spin in the direction you need.

Washing machine motors are collector. In my case, the connection block has six wires, yours can only have four.
This is what it looks like. We do not need the first, white two wires. This is the output from the engine speed sensor. We exclude them mentally or even bite off with nippers.

Next are the wires: red and brown - these are the wires from the stator windings.

The last two wires, gray and green, are the wires from the rotor brushes.

Everything seems to be clear. Now about the inclusion of all windings in a single circuit.

Scheme

Motor winding diagram. The stator windings are connected in series with each other, so two wires come out of them.

Connecting to a 220 V network

We just need to include the stator and rotor windings in series. Yes, everything turns out to be very, very simple.

We connect, check.

Rotate the motor shaft to the left.

How do I change the direction of rotation?

You just need to swap the wires of the rotor brushes with each other and that's it. This is how it will look on the diagram:

Spin the other way.

You can also make a reverse switch and change the direction of rotation of the shaft when needed.More detailed instructions for connecting the engine to a 220 V network, see the video.

Over time, washing machines become obsolete and fail. And any business person will certainly ask the question - "Where can the engine from a washing machine be used?" since this electric motor is highly revving and it may seem that it is absolutely useless in everyday life.

BUT! Don't rush to throw this engine away!

Thanks to this motor has a huge application potential. Let's figure out how to connect a collector electric motor from a washing machine using a speed control board without losing power.

Wiring diagram for washing machine electric motor

In order to connect the electric motor to the board or directly to the network, you need to deal with the wires it has. For this you need a multimeter. The motor has three (sometimes four) groups of contacts: Motor winding (can consist of two or three leads with a midpoint); Motor brushes (two wire leads); Tachometer (two wire leads); Thermocouple (two wire leads), the thermocouple is not installed on all motors, and is not used by us (not indicated in the figure).

1. It is necessary to find the wires of the Tachometer. Usually they are of a noticeably smaller cross-section and when "ringing" with a multimeter, they can show resistance or ring with a "chime".The tachometer is located at the rear (relative to the pulley) of the electric motor, with wires coming out of it.

2. The brushes are found by sequential "continuity" of the wires. The two wires should ring together and should also ring with the motor manifold.

3. The winding can have two or three wire leads. It is also found in a serial "continuity" of wires. If you have three leads (with a midpoint), you need to measure their resistance to each other. Two of them should show more resistance, the other end, less resistance. If you choose a winding with a higher resistance, you will get less RPM, but more torque. Conversely, a winding with less resistance will give more RPM but less torque.

4. The thermocouple wires have two wires and are usually colored white. In our case, they will not be used. Not shown in the figure!

Now, after all the wires have been found, it is necessary to arbitrarily connect one wire from the brushes to one of the wires of the selected winding. The two remaining reasons (from brushes and windings) are connected to a 220V network. If you want to change the direction of rotation of the rotor, you need to change the ends of the connection between the wires of the brushes and the winding.

After you have checked the operation of the electric motor from the mains, now it must be connected to the board. To do this, on the reverse side of the board, under the three terminals on it, there are letters "AC" "M" "T".

"AS"- denotes the terminal to which the 220V mains supply is connected. "M "- indicates the terminal to which the motor is connected. Those wires that were connected to the network above in the text."T"- the terminal to which the tachometer wires are connected.

How to best apply the board to your system

Since the motors from automatic washing machines are high-revving, they are still designed to work in this range. Since this is due to its cooling and the moment of force on the shaft (torque). Therefore, if you plan to use the engine at low speed with full torque (for all the power declared by the manufacturer), then you may need to install additional cooling. (cooler). Since the blowing of the installed impeller may not be enough due to low speed. If you touch the motor with your hand and you cannot hold it for more than 15 seconds, then additional cooling is required.

Since the engine is high-revving, its maximum power is achieved when adjusting the board from 600 rpm. All revolutions that will be lower may not have a maximum torque. Therefore, if your system requires very low rpm (from 1 to 600), you need to apply a belt drive of two pulleys (for example, from the same washing machine).

Thus, you "Kill three birds with one stone" will achieve very low revs, get even more torque (force on the shaft), but attack the same smooth intake with rev control.

If you need to connect two motors to the board at the same time, or power any motor on direct current, then you need to use a diode bridge at the output of the board with the further above connection.

Connecting the motor from the washing machine machine

If you still have a washing machine motor, you can figure out how to use it. For example, you can make a sharpener out of it. If you fix a special attachment in the form of a round sharpening stone on it, then you can sharpen knives, scissors, an ax and other tools.

You can also use an electric motor from a washing machine in construction. For example, when creating a foundation for a future home, you can make a "vibrator" out of it, which will come in handy when the concrete mortar shrinks. It can also be used for other purposes. The motor can rotate various attachments and set in motion any mechanisms.

Using your imagination and skills in such matters, you can come up with a wide variety of ways to use an electric motor. And of course, when implementing any option for using this motor, you will need to connect it.

How to connect the electric motor of a modern washing machine?

If you need to connect the electric motor of a modern washing machine to the network alternating voltage two hundred and twenty volts, then the features of this part should be taken into account. Their features are as follows:

They do not need a starting winding.
You don't need a starting capacitor to start.

To start, we need to connect the wires on the engine in the right way. We will not use the two white wires on the left. They are needed to measure the speed of the electric motor. The next in line is the red wire. It goes to the stator winding. There is a brown wire behind it. It is also directed to one of the stator windings. The gray and green wires are connected to the motor brushes.

In order to present the connection diagram to you more clearly, we have prepared the following diagram:

We will connect one wire of 220 volts to one of the terminals of the winding. Connect one of the brushes to the next one. Connect the second 220 volt wire to the remaining brush of the washing machine motor. As shown in the diagram below:

After that, you can turn on the engine to the 220 network and check its performance. If you did everything correctly, you will see how the moving part of the motor rotates and you will hear the noise of its operation. If everything went well, then the engine is ready for use. By the way, with this connection, it moves in one direction. What needs to be done to change the direction of rotation? See diagram:

As you can see from the schematic display in the figure above, in order to change the direction of rotation, we needed to swap the connections of the electric motor brushes. After reconnecting the engine, check its performance again by connecting it to a 220 volt network.

By the way, in order to make your work easier, we decided to add a video instruction. In which the whole process of connecting the engine from the washing machine to electricity is described.

The method of connecting a motor from a modern machine in this article is based precisely on the material that is presented in this video. Therefore, we would like to thank the author of this video and watch it very carefully:

How to connect the motor of an old car?

Correctly connecting the electric motor of the machine is not so easy. But if you know how to do it, then it will not cause problems.

First, we need to find two pairs of outputs. In order to understand where they are, we can use a multimeter (tester). Select one of the winding leads and connect the tester probe to it. With the remaining probe of the multimeter, we will check the other leads to find a pair.

Thus, we will find the first pair. The two conclusions that remain form another pair. Now we need to understand where the starting and working windings are. To do this, you need to measure the resistance. The starting resistance will be higher.

Scheme

And so, we have already found a working and starting winding. Now we can connect the motor using the schematic drawing you see next to it. The diagram shows:

PO - starting winding. It is needed in order to create an initial torque in any direction.
ОВ - excitation winding. It is also called the working winding. It is needed to create a magnetic field of rotation.
SB - switch (button) for short-term switching on of the software to the electrical network of two hundred and twenty volts.

If it becomes necessary to change the direction in which the rotation of the motor will be directed, you will need to swap the software pins. With such a change, the direction of rotation will be reversed.

When you conduct a test connection and launch the engine, do not forget to take care of your safety and the safety of those around you. Be sure to secure the motor. This will prevent it strong vibrations and unnecessary movements.

We hope that this post helped you cope with connecting the washing machine motor yourself. Keep reading our website and have a great day!
