Hi all,
I am trying to make a generator out of an old motor I have. It is a GE 208-230v, 1/4 hp, single phase, 980 RPM motor. Based on the wiring diagram, I’ve hooked up a capacitor (7.5 mf/370v).
I’m spinning the rotor of the motor via a bicycle, and I’ve figured out the gear ratio so I know how fast I have to pedal to (hypothetically) generate electricity (that is, generate positive slip).
The problem is that I can’t seem to generate more than 0.7 v or so (AC). This is seemingly due to the electromagnets being not energized and hence not creating a magnetic field. I’ve tried a few things, so as flashing the motor with 12v DC current for a moment to try and energize the magnetic field.
My question is: how could I hook up this motor so that I can generate electricity via spinning the rotor?
As an aside, the motor works in the sense that I can connect it to 120 v AC power and the rotor spins. I only run it for a second or so though as I don’t want the low voltage to damage the motor.
