Comparative study on switched reluctance and flux-switching machines with segmental rotors

Switched reluctance machine (SRM) and flux-switching machine (FSM) with segmental rotors are different in winding patterns and control strategies. The electromagnetic characteristics of the two machines, including magnetic field, static torque, torque ripple, iron loss and efficiency, are compared by means of analytical calculation and finite element method in this paper. The analytical results of this paper provide a theoretical guidance for choosing between the two types of machines in specific applications.
