Analysis of Permanent Magnet Synchronous Motors in Hybrid Electric Vehicle

When designing Permanent magnet motors, cogging torque is a crucial factor, especially for high-precision applications. To improve PMM application effectiveness in Hybrid Electric Vehicle Application, Cogging torque must be reduced in PMMs. Using this research paper, I have compared two methods to reduce cogging torque: 1. The use of dummy slots in stator and the addition of flux barriers to the dummy slots, which are implemented in the PMSM as a combination of 10 pole 36 slots. Permanent Magnet Synchronous Motor Parameters like motor torque, cogging torque, cogging torque ripple, efficiency, and output power were evaluated. The study provides insights for enhancing PMM performance in high-precision applications.
