Description

technical field [0001] The invention belongs to the technical field of inductance testing, and in particular relates to a switching reluctance motor global nonlinear inductance testing device and testing method. Background technique [0002] Due to the advantages of simple structure, convenient control, high reliability and low cost, switched reluctance motor has been valued and recognized by all walks of life. The switched reluctance motor is a kind of motor with high magnetic saturation, and its parameters are nonlinear. Especially the inductance parameters of the motor, the inductance of the motor is not only related to the rotor position of the motor, but also related to the winding current of the motor. The traditional LCR meter used to measure the inductance of the motor ignores the saturation characteristics of the motor and the non-linearity of the inductance, resulting in huge errors in the performance evaluation of the motor. Therefore, the measurement of the sat...
