Description

Technical field

[0001] The invention relates to a method for detecting whether the position signal of a switched reluctance motor is abnormal, in particular to detecting whether the position signal of the switched reluctance motor is abnormal or not under the normal operation state of the switched reluctance motor to make the switched reluctance motor drive more stably method. Background technique

[0002] Generally, a switch reluctance motor must have a position signal when driving, and the position sensor can accurately grasp the starting point of the change of the forward / reverse rotation of the motor, and can control the forward / reverse rotation of the switched reluctance motor. For the N-phase switched reluctance motor, N position sensors are used to master and control the forward / reverse rotation of the switched reluctance motor. Generally, in order to save costs, a three-phase switched reluctance motor uses only one position sensor. The switched reluctance motor tracks and...
