Three-Phase Reluctance Generator with Permanent Magnets Buried in Stator Core

In this paper, we propose a reluctance generator (RG) which has permanent magnets in the stator core. The RG has a doubly salient pole structure, and generates electric power by using magnetic saliency. First, using a finite element analysis (FEA), we compare a single-phase and three-phase RGs about power density, distribution of leakage flux, and cogging torque. We examine effects of an increasing number of poles. Next, we describe characteristics of a trial three-phase RG, which has an efficiency of more than 90%.
