摘　　要：齿槽转矩是引起永磁步进电机振动、噪声甚至影响其安全运行的主要因素.在描述该种电机结构的基础上,研究了供电方式对电磁转矩的影响,分析了削弱永磁步进电机齿槽转矩的不同设计措施,给出了其齿槽转矩的数学表述.以一台永磁步进电机样机为例,用有限元法计算了几种不同设计措施对电机齿槽转矩的影响,并进行了对比研究,从而为该种电机的设计提供了可以借鉴的理论依据.图8,表1,参8.The cogging torque was the main factor that causes a PM stepping motor to be vibrated,noisy and even influences its safe operation.After introducing this kind of motor structure,the effect of the power mode on the electromagnetism torque was studied,different measures of reducing the cogging torque of PM stepping motor was analyzed,the mathematics description of cogging torque was given out.The calculation and comparison of several different design techniques for reducing the cogging torque were finished by the finite-element methods.Theoretic reference for designing this kind of motor is offered.8figs.,1tab.,8refs.
