摘要：
To propose the methods for cogging torque reduction in permanent magnet machines, theoretical reasons of cogging torque are studied in this paper and the qualitative analysis is performed before quantitative calculation with finite-element method. And the effects of slot opening widths, unequal thickness magnets as well as pole-arc factors on cogging torque in PM machines are then analyzed with finite-element method. Finally, the methods to reduce cogging torque in PM machines are summarized, which demonstrate that with proper methods the cogging torque can be significantly decreased.
