Welcome to JUST ANSWER small engines, let me try to help you !! Make and model number? If this is power washer, or pump, the armature is stuck, With it unplugged, you need to get to the fan and see if you can manually turn the shaft. If you can get it to turn, the motor likely will start. If you can't turn it, then it will need to be dis-assembled to repair the motor.

it is a air compressor

OK, is the air pressure released? Same problem, see if you can turn the motor by hand.

Probably a bad motor, if the compressor end was locked, the motor would not have ran.
