© 2018 IEEE. In this paper, the skew angle of the permanent magnet synchronous motor (PMSM) for electric vehicles (EVs) is studied. The stability of the output torque of the driving motor is important for the EVs. The influence of skew angle on the Back-electromotive force, cogging torque, and output torque are studied by finite element analysis. The optimum skew angle of the stator slot is analyzed for the prototype. The results show that the proposed PMSM has better comprehensive performance after the optimization of the skew angle.
