Current Superimposition Variable Flux Reluctance Motor Using the 5th-Order Magnetic Flux

Abstract

　We have developed a current superimposition variable flux reluctance motor that has 10 salient poles in the rotor and 12 slots in the stator. However, iron losses of this motor in the high rotation speed is high because the number of poles is large. In this paper, we propose a current superimposition variable flux reluctance motor that has 8 salient poles and 12 slots. The characteristics of the 10-pole-12-slot and 8-pole-12-slot current superimposition variable flux reluctance motors are compared using finite element analysis under control.
