Basic Characteristics of a Reluctance Generator with Permanent Magnets Buried in the Stator Yoke

Abstract

A reluctance generator (RG) has various desirable features, including simple construction, high reliability, and low cost. Furthermore, it is suitable for an ultra-high-speed generator because the rotor of the RG is made of iron steel. However, the RG system is complicated, because it needs to detect the rotor position angle and requires a dc power supply for the driving circuit of the stator winding. For this reason, the RG has not been used in practical applications. In this paper, we propose a new RG with a permanent magnet in the stator yoke. The linkage flux of the stator winding from the permanent magnet changes with the salient-pole rotor. The experimental results obtained with a trial RG indicate that it has a very simple construction and high performance.
