Bigger Servicing: The slip rings and brushes from the rotor have to have substantial upkeep, and the exterior equipment are have to have.

I have a motor I'm endeavoring to get to work. The tag on it says its a three phase asynchronous motor. 110v and I feel The present is six.9amps. After i turn it on it hums and when i spin the motor it's going to begin to go and will spin pretty slowly and gradually but as soon visit as any resistance is utilized it stops and just hums.
