Monitoring motor vibration: it can harm both energy and ...

However, if the vibration persists, cut off the supply to the motor: if this has the effect of stopping the vibration, then the problem is most likely an electrical unbalance within the motor. If the vibration continues as the unpowered motor winds down to a stop, then look for a mechanical unbalance.
