What determines RPM speed of Electric motor?
From my research its the windings in the motor and voltage.
So my question is, can you keep increasing the speed of the motor by constantly increasing the voltage BUT lowering the amps?
So say running a small toy 12v dc motor with a car ignition coil? Coil has lot of volts but not much amps.
I would start the motor with 12v so that it gets to its 12,000rpm its operating speed, then once upto top RPMs, I would disconnect the 12v and connect the 30,000v from the coil to power the motor.
What would happen?
1. Motor would continue to speed up past 12,000 rpm?
2. Or slow down because there isn't enough amps from the coil?
(please ignore that the windings in the motor would spark from lack of insulation, this question is theoretical)
