why AC current directly into a DC motor would hurt it?

Question

And does it eventually break it completely?

In: Engineering

Answer 1

Ac motors accept “pulsing” or on/off current by orienting magnets that get energized according to the alternating current. In the simplest terms possible, a direct current (dc) would just put constant current into the nearest magnet in the motor and instead of turning the motor it would expend its energy into heat without expelling any energy spinning the motor.
