Starting Electrolux Washing Machine Motor Without Programmer: Cable Configuration?

Question

Hello, I have a problem with controlling the inverter with the motor removed from the Electrolux washing machine. Namely, 5 cables for the programmer come out of it, the question is how can I start the engine without the programmer connected using only these cables?

Examine connections at programmer and inverter. Determine mass and then the remaining signals. Measure. Something may become clear.

Maybe it is possible to open this inverter's housing. Sometimes derived (lead-in) terminals and control signals are described on the PCB. Maybe based on the components used, e.g. integrated circuits, it will be possible to determine how this inverter is controlled.

I support. Most likely it is a BLDC motor. It cannot be started without the matching power supply. Giving power to 3f it will be burned. To be sure, look for information on the manufacturer's website. And the easiest way is to open it. If the rotor is a strong magnet, then BLDC.

It would be useful to have some information about the engine itself, its type. Some photo. Possibly information about the model of the washing machine it comes from. The fact that the motor has several cables led out does not necessarily mean that an inverter is needed to start it.

Here are the photos, the parts come from the electrolux washing machine production year 2008/9, as to the type of engine from the construction site, it is concluded that it is three-phase.

This motor cannot be connected directly to the 230 mains. Note that the motor nameplate contains information that it is adapted to be supplied with a slightly reduced voltage of 195V. You would need to make an appropriate inverter, maybe you could use elements from the original programmer. In practice, it may turn out that the amount of work put into recovery of this engine exceeds the real benefits resulting from its reuse.

The inverter itself is a white box next to it, 230V is connected to it, but the motor is controlled using 5 cables going to the programmer and here is the layout and what can be connected to to move the motor shaft

I will open it and let you know what came out

As for the old woman, the cubes have not been cut, so the only thing left is to control the system

Added after 13 [minutes]:

disassembled very easily, the rotor looks like in the picture the winding too

jack63 · Answer

It looks like an ordinary induction motor. There is something (?) Inside the stator that could be a rotor position sensor. You did not answer the question about a possible magnet in the rotor.

darkavvenger · Answer

I wrote that he took out without a problem, which meant that there is no magnet there, as if it were without a problem, I would not get it out.

Hello, I have a problem with connecting the washing machine motor from disassembly under 230. The only thing I know is the motor from the washing machine whirlpool, I do not know the model, spinning probably 1100 rpm. 9 cables come out of the engine, the last two go to the rear of the engine, I know. My question, does anyone know how to connect it with high speed and where (which cables to connect) the capacitor?

jorgetemp · Answer

@darkavvenger have you had any luck controlling the original inverter, so it can run the motor? I managed to identify the 4 wires that send signal to the inverter from the main board, but different from GE and other 3Phase inverters I have seen on the Internet that use 5v communication, the Electrolux inverter seems to have GND, SIGNAL (some protocol I don't know), and the 2 other wires have 7 and 18 volts. Would be great to control this motor with the original inverter and not having to buy a VFD.
