I have an induction(?) motor that might be 30 years old. It's principal dimension is ~50mm so fairly small. It's actually the fan motor from a fan heater. It has one winding and runs off 240VAC with a DC resistance of 375Ω. There is just one simple stator winding. It's just like:-
I also have a 12VDC source of sufficient capacity. How can I get the motor to rotate using the 12V direct source? All I want is rotation. It doesn't have to do any useful work just go round. And the speed is irrelevant, any constant rate is fine. Beyond any rhyme or reason I'm assessing the feasibility of using it as an on /off indicator in a Steampunk project. Steampunk gives us licence to do stupid stuff.
Initial thoughts: some form of siney wavey generator + 12V audio amplifier chip like a LM384 (5 Watts)? Horrible impedance mismatch but might it rotate? Or is this just too stupid? Can feasibility be assessed without building it?
I though that running AC synchronous motor with DC might help but that motor is properly voltage matched and seems to be performing work.
