Abstract
An apparatus and method for determining an operational state of a motor are described. The apparatus includes a sensor or detecting vibration and a processor coupled to the sensor. The processor converts sensed vibration signals into the frequency domain to produce a vibration characteristic, and determines a current operational state of the motor based on the vibration characteristic, wherein the current operation state is determined from at least two different operational states including at least one idle state and at least one working state.
