Abstract
The invention discloses an exciting-winding self-inductance type modeling method of a three-phase doubly salient electro-magnetic motor. The method is characterized in that on the basis of the property that the motor exciting-winding self-inductance value, at a position where rotor teeth are aligned to stator teeth, of the doubly salient electro-magnetic motor, is determined by armature current on the stator teeth, difference between the exciting-winding self-inductance value when the armature current under the phase is not zero and the exciting-winding self-inductance value when the armature current is zero is obtained from the position where the rotor teeth are aligned to the stator teeth, and then the relation between the armature current under the phase and the exciting-winding self-inductance value can be fit; then the exciting-winding self-inductance value at the position where three rotor teeth and the stator teeth are aligned under one electric cycle through the three-phase pivot current is determined, so as to fit a relation curve of the exciting-winding self-inductance value and a rotor position angle. According to the method, the inductance parameter modeling can be finished by simply fitting the relation between the armature current of one phase and the exciting-winding self-inductance value, so that the method is a doubly-salient electro-magnetic motor modeling method which is simple, convenient, easy to perform, and high in accuracy.
