摘要

The flux reversal permanent magnet machine (FRPMM) has a simple structure, good fault tolerance and high efficiency, and shows good applicability in various high and low-speed operation occasions. However, the problem of large torque ripple has become a key factor restricting the further improvement of torque performance. A novel FRPMM with auxiliary teeth and permanent magnet (PM) chamfer is proposed. The auxiliary teeth structure without PMs replaces half of the stator teeth, and the PMs near the air gap side are arched to form PM chamfer. The key parameters are obtained by sensitivity analysis. Then, based on the multi-objective genetic algorithm (MOGA), the parameters are optimized by response surface method (RSM) and single parameter scanning. Finally, the electromagnetic performance of the proposed machine is compared with that of the conventional machine. The results show that the output characteristics of the machine are still significantly better than those of the conventional FRPMM under the premise of reducing the use of PMs.
