为了减小齿槽转矩，在表面贴装永磁电机的电机设计中可采用多种技术。本文描述了各种技术（包括经典技术和创新技术），并对每种技术进行了理论论证。为此，介绍了齿槽转矩机构的简单原始模型和傅里叶分析。因此，它强调了一些技术并不总是可用的，一些众所周知的技术如果使用不当甚至可能贬值。此外，还讨论了反电动势的影响。
Several techniques may be adopted in motor design of surface-mounted permanent magnet motors in order to reduce the cogging torque. This paper describes the various techniques, (both classical and innovative techniques), giving for each of them a theoretical justification. 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 the well known ones may be even depreciatory when not used correctly. In addition, effects on back EMF are discussed.
