Abstract

Doubly excited brushless reluctance machine (DEBRM) has gained much attention in the area of variable-speed constant-frequency generating systems and adjustable speed drives. Two types of reluctance rotor structure, axially laminated and simple salient rotors, are suggested in the DEBRM development. Due to the unconventional pole number combination of the stator and rotor, performance evaluation of the DEBRM with different rotor structures is difficult. A comparison study of two rotor structures of the DEBRM is presented in this paper by finite element analysis. It is shown that by calculating selfand mutual-flux linkage of the dual stator windings as the function of rotor positions, performance of the complicated DEBRM can be evaluated conveniently. Various advantages and disadvantages of the DEBRM associated with the two rotor structures are also discussed
