Abstract Torque quality of Interior Permanent Magnet Synchronous Motor IPMSM is very sensitiveto some of rotor parameters and dimensions These sensitivities can be exploited to reduce thecogging torque and torque pulsation This thesis presents a new analytical approach to mitigatethe cogging torque using a simplified magnetic circuit model The method results in a newair bridge shape with very low cogging torque The Finite Element Method FEM resultsshow that the presented design not only mitigates the cogging torque but also significantlyreduces the total torque pulsation Finally the optimal design is presented based on torquequality of the motor at rated load and steady state conditions and using magneto staticanalysis Compared to other methods this method is very affective in suppressing the torquepulsation
