I've been given a bench grinder (rated for 150W @ 230V), which uses a (psc motor?), just an induction motor with start/run capacitor/winding (it has no centrifugal switch whatsoever).
I always wanted to use an atmega to make a 3 phase inverter for motor control, but the high voltages and currents involved at mains have always set me back.
So I thought that being useless as a grinder, because it bogs down as you try to sharpen anything (besides that I already have one three times as powerful), I could try rewinding it for 12 volts three-phase and use a pc power-supply to play around with it.
That way I'd save the mains-filtering and rectification part of the inverter, and yet have 5 volt supply for the micro out of the box.
However, been looking for a while on the internet and found nothing related, so just wanted to ask, would it be worth the effort?
I still have to count motor's number of poles to check it can be three-phase, but the fact nobody has ever done this before leads me to ask.
