Recently, as automotive tends to be electricized and leisure space, traction motor of automotive become more important. In addition to price of rare earth magnet is flexible. So nonrare earth magnet traction motor should be studied. This paper presents a design strategy of Wound Field Synchronous Motor(WFSM). The design strategy is that confirm main factors which have an major effect on torque and torque ripple through design of experiments. Then, confirm change tendency of torque, torque ripple and induced voltage through main design factors which are pole arc, thickness of rotor and stator, and eccentricity using response surface methodology. With this strategy, this paper presents an improved model for torque ripple reduction and induced voltage compared to initial model.
