I was given a heavy old bench grinder 110v ac motor with shaft for a wheel on each side. The motor plate is missing so I dont know anything about the motor.
Its plug was missing so I shoved the bare wires into an outlet to test and it powered on fine.
I put a plug onto it and it powered on but sounded different and then started smoking and made a pop sound. I unplugged it and waited an hour and plugged it back in and its just making a buzzing sound.
The only thing under the hood is a switch and this part in the pictures below. Is the polarity important on this setup?
