An Overview of Rotor Pole Optimization Techniques for Permanent Magnet Synchronous Machines
摘要
Abstract
The electromagnetic performance of permanent magnet synchronous machines (PMSM), such as the electromagnetic torque, the torque ripple, and the noise and vibration, is related to the waveform of the airgap flux density. Reducing harmonic contents of the airgap flux density can effectively mitigate the cogging torque, suppress the torque ripple, and decrease the noise and vibration level of the machine. For the surface-mounted permanent magnet (SPM) and interior permanent magnet (IPM) synchronous machines, the harmonic contents in the airgap flux density can be reduced by optimizing the permanent magnet on the rotor or by optimizing the rotor core shape (rotor pole optimization techniques), respectively. This paper overviewed and summarized domestic and abroad research of the rotor pole optimization techniques of the PM machines in recent years. Finally, the future developments of the rotor pole optimization techniques were discussed.关键词
