What is Mitigating Cogging Torque in PMSM about?

This paper proposes a method to mitigate slot harmonic cogging torque in permanent magnet synchronous motors (PMSM) caused by unevenly magnetized permanent magnets. It establishes the relationship between the remanence of the magnets and cogging torque, explains the generation of slot harmonic cogging torque, and introduces a new mitigation method verified through finite element analysis and experimental results. The study emphasizes the importance of addressing manufacturing errors in motor design to enhan
