Abstract: This paper presented an interphase coupling switched reluctance motor with short flux path structure. Its rotor is made up of cast aluminum and silicon steel 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, higher cooling capacity. The characteristic of the motor structure was analyzed. A five phase 10/8 poles SRM was analyzed for example. The performance of motor and the harmonic components of the radial force wave were verified by finite element method, which compared with normal SRM. The results show that this kind of new SRM improves the performances of average torque, power density, efficiency. This paper provided a new designing thoughts for high power density and high efficiency motor, which has theoretical and practical value.
