Is this the right way to wire an old, one capacitor washing machine motor ? Answered
I actually have an old Brandt 556T washing machine, and I'm trying to replace the internal mechanical program with an arduino some electronics. Actually I'm trying to directly run the motor at it's both speeds, and both directions. So, the motor is a Selni V689, and I also have another motor laying around. It's a Selni V604. The two of them seems to be using the same wiring. So, for the moment I'm using the older one (the V604) to experiment.
After some googling, I understood this kind of motor uses a single capacitor to select the direction of the rotor, and it enables the motor to start without help. We can wire it without the capacitor, and spin it manually to start it, or use the capacitor to start it properly.
So, I ended up with the schema linked here.
It seems to be working, except for the old V604 which, in second speed, runs faster in one direction that the other... But for the V689, it seems to be okay.
I need to ensure that my wiring schema is really ok, then I'll try to use as few relays as possible to be able to fully control this motor with 3.3/5V logic.
If anyone can help me confirm that, I'll really appreciate it ! Thank you guys !
NB: I firstly thought there was a problem with the power consumpsion of those motors, but I was wrong, it's fine.
