Bosch J52BCM-0111 Washing Machine Motor: Connecting to Speed Controller & Capacitor Usage

Hello.
I have a motor from a Bosch washing machine model J52BCM-0111. I would like to connect it to the speed controller. I have a question how to do it and what regulator to buy? Do I have to use a capacitor? It has 5 wires
Please help!

You must have an inverter for this motor.

And in washing machines especially newer, we understand that there are inverters? Of course not Maybe supernova, very expensive washing machines are fitted with inverters, but I have never encountered anything like this because in most washing machines, apart from programmers, only the regulator (s) on the triac sits.
Was there a control board or a speed controller in the washing machine besides the motor (sometimes on one board)?

Hello, what Bosch model did you get it from, it will be easier.

variable speed, 195 volts, 3 amps, 310Hz, 3 HP, induction motor, 17 500 rpm max.

Just because you haven't met something doesn't mean that it doesn't exist. How do you use three-phase 50 Hz phase controllers to make three 310 Hz phases?

Rather not 3HP (three horsepower), but 3PH (three phases).

Hello, it looks like this engine is adapted to the inverter for 3 phases, but you can not connect it directly to the so-called force because you will burn it, you can not exceed the interfacial voltage of 195V, its speed is affected by frequency, brown white gray is 3 phases and two black tacho you have to wander such a transducer which from 220 V one phase will make you three, .a frequency = [revolutions] would be on the potentiometer, it's quite complicated what I write but similar power systems are used in cooling evaporator fans powered by 12 V is popularly called the fact that the converter located in the motor generates a rotating magnetic field as to the voltage it produces, it is impossible to check if the motor has open photo covers, I could send you such a converter after taking a photo. I will not be able to run it now because it has a processor and I did not copy programs from other converters, if you look for it, they are definitely separate modules

PS Oh crap, this is how 220V air conditioning compressors work and they have external inverters to change the speed [efficiency] after all, on 3 power cables there is no option to start it without a capacitor, it's a different generation

Here there is an example of a controller diagram for this type of engine.

The motor from the washing machine that is being distracted here is a regular induction motor, only at a slightly higher frequency. You show the BLDC motor driver. And this is something completely different.

It is better to look for another engine if it makes sense to try to find a regulator for it.
I saw on the Allegro speed regulators for brush or induction motors at a dozen or so zlotys. Looking at this engine, I thought it could be combined with some inexpensive solution. I had an unnecessary motor and thought to use it, but if it would cost a fortune, it would probably be better to buy a single-phase motor to connect it to the regulator.

If you had the original driver from this washing machine, maybe it could be used, although I doubt it. If not, better look for another motor, preferably a brush one. It's easiest to regulate.

Thanks for the help

Hello! Old topic, but not closed and still valid for DIY enthusiasts. They are washing machine motors, the brush motors, with a tachometric generator on the axis. Simple voltage-cutting regulators can be used for them, but the torque is very low and practically such a motor is only suitable for a fan. But by using a tacho-generator for feedback, you can even drive a wood lathe, grinder, etc. with such a motor. You cannot stop the motor axis with your hand. The regulator circuit is based on the TDA1085C integrated circuit.
In the photo I present such a regulator.

Hello Friend!

What you write makes sense and I need something like that.
Could you share the diagram of your regulator?

The controller works based on the TDA1085C system. Under the slogan Drehzahlregelung für Universalmotoren, at http://zisoft.de/elektronik/drehzahlregelung, the construction of such a ragulator is described, along with a diagram, list of elements, and a plate.
I can also sell a regulator I built. Please message by email.

The 0.4 kW LS inverter (IC5 series) can be purchased for around PLN 350. In this inverter, you can easily set the maximum motor voltage, and from a lot of other parameters. Powered from one phase, it generates 3 phases to the motor. Vector control and almost 100% of the torque from about 5Hz.

But this was not a 3-phase motor, but a universal one. Universal motors are single-phase motors that can be found in washing machines and dryers. They can be powered by direct or alternating voltage and are equipped with tachometric generators so that the rotational speed can be determined. Because these engines do not have a fixed base speed, they will accelerate to break the anchor. Speed control is therefore necessary. With a small, constant load, phase control with a simple dimmer module is sufficient. Such a simple phase control is not enough for use in a home saw, for example. The Motorola TDA1085C system has been specially designed to regulate washing machine motors.

Somehow I do not see that it is a universal engine. Three phases, 195V and 310 Hz - only inverter.
