Abstract :
This paper describes the better shape design of the permanent magnet to reduce the torque ripple in interior permanent magnet synchronous motors (IPMSMs) without deteriorating other performances. We make various motor models to analyze the cogging torque and the torque ripple. Using the two-dimensional finite element method, these motor models are discussed under the same condition. As a result, we have found the better shape of the permanent magnet.
