This paper treats method for improving torque performance in Interior Permanent Magnet Synchronous Motor
(IPMSM). IPMSM is widely used for traction motor of electric vehicle. This type of motor produce high torque performance
and wide range of operation. On the other hand, IPMSM has several disadvantages which are cogging torque and torque ripple.
Those can be the causes of noise and vibration. In this paper, we design optimal shape of motor stator for improving torque
performance of traction motor for electric vehicle. Notch design is applied to stator and the effects are verified by Finite
Element Analysis (FEA).
