Use a DC motor. If it's ac, it will vibrate. If it's DC, it will just spin normally.
Just make sure the voltage of the motor is matching the source of power.

If it's just a transformer with nothing else, then the output will be ac. You need diodes or rectifiers to change ac to dc.

Post a link to the transformer.
