Research On Double Salient Electro-Magnetic Motor Speed Control System By Full-Bridge Converter

Double-salient motor is a new type of AC motor appeared at 1990s. Presently, domestic and international researches are mainly concentrated on permanent-magnetic double-salient motor. Embedded researches about electro-magnetic double-salient motor have not gone on yet.This paper first briefly introduced the structure and basic operation principle of the new electro-magnetic double-salient motor. Then, according to the characters of the motor, dynamic mathematic model are set up, based on which simulation is carried out using the software MATLAB. All kinds of trouble states of the motor are analysed, meanwhile simulation and experiments are done to prove the exactness. At last, this paper introduced the design of hardware of the electro-magnetic double-salient motor speed-controlling system by full-bridge converter. The result of the debugging on the system show that the system possesses excellent running performance and prove the theoretic analysis and simulation to be right.
