Abstract:
A multiphase alternating current permanent magnet synchronous electric motor is coupled to an actuator. A sensorless electric motor drive control system controls operation of the electric motor. An initial phase angle and a rotational speed of a rotor of the electric motor are estimated. Operation of the sensorless electric motor drive control system and the electric motor are monitored using the estimated initial phase angle and the estimated rotational speed of the rotor of the electric motor. A fault in one of the sensorless electric motor drive control system and the electric motor is detected based upon the monitored operation.
