基于位置信号与非导通相电流的双凸极电磁电机位置传感器故障诊断方法

Reliable rotor position information is essential for accurate commutation control of motor drive system. Traditionally, hall sensors have been widely used to obtain rotor position information. The fault of position sensor will lead to the confusion of the commutation logic, which will reduce the output torque of the motor and even fail to operate normally. Therefore, fault diagnosis of position se...
