Abstract： 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 waveform 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.
