Abstract

To enhance the operation efficiency of generators in variable wind conditions, this paper proposes an outer rotor doubly salient permanent magnet reluctance generator(ORDS-PMRG). First, the operation principles of ORDS-PMRG are presented. Then, the magnetic modulation effect of the multi-tooth structure on generator air-gap flux density is analyzed. Next, the operation modes of the proposed generator are analyzed and can be flexibly switched by changing the winding connection methods. Meanwhile, the electromagnetic characteristic analysis is developed based on the finite element model. The results indicate that the proposed ORDS-PMRG has more operation modes and higher power density compared to traditional doubly salient permanent magnet reluctance generators.
