在设计表面安装永磁电机时，可以采用几种技术来减小齿槽转矩。本文介绍了各种经典和创新的技术，给他们每个人的理论依据。为此，一个简单的原始模型的齿槽转矩机制和傅立叶分析。因此，需要强调的是，有些技术并不总是可利用的，其中一些甚至可能是不可取的，如果不正确使用。此外，还讨论了齿槽转矩消除对电机反电动势的影响。
Several techniques may be adopted in designing surface-mounted permanent-magnet motors in order to reduce the cogging torque. This paper describes various classical and innovative techniques, giving a theoretical justification for each of them. To this aim, a simple original model of the cogging torque mechanism and a Fourier analysis are introduced. As a result, it is highlighted that some techniques are not always utilizable, and some of them may even be deprecatory when not used correctly. In addition, effects of cogging torque elimination on back electromotive force are discussed.
