摘　　要：为提高汽车发电机的绕组性能,以96槽16极爪极电机定子绕组为例,分析和设计了一种由两组三相波绕组构成的定子绕组。通过Ansoft有限元分析软件,对该绕组通入三相对称电流产生的气隙磁场和总谐波畸变率值(THD)进行了计算分析,并与传统三相波绕组的整距和短距接法的结果进行了比较。分析比较结果表明,采用该方法生成的三相定子绕组产生的磁场波形和谐波含量都满足设计要求。按该设计方案生产的汽车发电机绕组实物图验证了该设计方法能满足大功率和结构紧凑的要求。In order to improve the properties of automotive generator, a design method of automotive generator stator windings -96 slots and 16 poles claw generator, for example, was analyzed. With finite element analysis software Ansoft, the flux density waveform generated by three-phase symmetrical current in the stator windings and its total harmonic distortion（THD） value were calculated. Compared with the traditional full-pitch windings and short-pitch windings, the analysis results show that the magnetic field wavefonn and harmonic content can meet the design requirement. The prototype of an automotive generator windings was also given to verify that the design method can achieve the high power and compact structure requirements.
