Problem of starting motor washing machine

[tnerual]

Hello, I recovered a washing machine engine to make a potter's wheel.
Connected with the control of the machine, it works, but according to the programs, therefore impossible to regulate the speed.
I tried to connect it live, but I can not do it.

Based on my research, it would be a universal driver.
On the other hand, without counting the two speed regulation wires, there are 5 wires, 2 connected to the coals, 3 on the stators, through two kinds of small plastic boxes.
The current flows between the two wires connected to the coal, likewise between the other three wires.
I tried serial connection, parallel, but nothing.

The references on the motor plate are:
MCA 52 / 64-148 / VES2
12000rpm 2 A 380 W
220 / 240 V 50 / 60 Hz clF / F

If anyone has a solution, thank you in advance.

Why do not you use a simple motor with pulleys and belts as a reducer?

the engines of older washing machines over 30 years were simpler, to see to the breakage.
the boxes must be capacitors and there must be several motors actually wound in the stator washing, spinning, with motor windings out of phase by the capacitors.

I made a recycling of this kind a few years ago, like you I did not know what were the wires to connect to run in small and high speed.

Everything happened on a connector to (7 or 8 son?), So I connected the ground wire to the motor and tried with the other two wires from the mains socket by touching the connector contacts. To see who was doing what and run the engine (no load).

Quickly and after a few tests and a few small flash of bad contact, I have nothing toasted and succeeds in doing test / error to find the 2 speeds.

With a small oscilloscope (and even a multimeter) you can better identify yourself by measuring the motor running on the machine.
Reflecting on the capacitors we also find ..

Now more and more machines are equipped with electronic dimmers. It's not clear that there are still capacitors.
A priori it is not an asynchronous motor ...

That's what I want to do, in fact I'm trying to do with a recovery engine. But it's more complicated than expected.

I also tested all possible combinations without success, except for a big spark on a connection.
I hope I have not done anything.

I got inspired but without success.
That said the two circuits that power the rotor and the stator are independent so I do not see how the current can pass.
Unless you bridge a stator input with a rotor input and feed as on the shema ????
