Abstract :
A simple analytical method is developed for determining the optimal combination of stator pole and rotor pole numbers for maximum torque from a multi-tooth flux-switching permanent magnet (FSPM) machine. In addition, the rotor pole width and split ratio are optimized by finite element analysis. The optimized multi-tooth FSPM machine exhibits a significantly larger torque capability and requires a significantly lower volume of magnet material than a conventional FSPM machine. The performance of the proposed multi-tooth FSPM machine is validated experimentally.
