Performance Comparison of Wound Field Flux Switching Machines

A flux switching machine (FSM) with a segmented rotor and non-overlap windings is an attractive alternative for driving high torque density applications. However, a rotor with segments makes the motor less robust as well as difficult to be assembled, whilst, FSMs with salient rotor and overlap windings inherit high copper losses and less efficiency due to high coil volume. In this paper, performance analysis of a novel structure of FSM with non-overlap windings and salient rotor are compared with 10Slot-8Pole segmental and salient rotors FSM. Deterministic optimization is adopted to enhance the characteristics of proposed machine. Using two-Dimensional Finite Element analysis, the proposed optimized machine are found to exhibit high torque and power than 10Slot-8Pole segmental and salient rotors FSM.
