The Research on an Inter-phase Coupling Switched Reluctance Motor With Short Flux Path

This paper presents an inter-phase coupling switched reluctance motor with short flux path structure. Its rotor is made up of cast aluminum and silicon steel U-shape core, in order to ensure the flux closed with a shortest path. This structure could provide higher power density, lower iron loss and manufacturing cost, lighter weight and higher cooling capacity. A five-phase 10/8 poles SFP SRM is analyzed in this paper. The performance of torque and the harmonic components of the radial force wave are verified by finite element method, which compared with normal SRM. This paper provides a new designing thought for high power density and high efficiency motor, which has theoretical and practical value.
