Optimization procedure for the design of interior PM motors based on level-set based topology optimization is presented. The nonlinear ferromagnetic material boundary is represented by a level set function and the movement is driven to reduce the torque ripple while maintaining the target operational torque with the motor volume constraint for the wide speed range operation. The effectiveness of the...
Interior permanent magnet (IPM) motor is widely used for many industrial applications and has relatively high torque ripple generated by reluctance torque which results in noise and vibration. Since the configuration of the stator has great influence on reluctance torque, design optimization is necessary to improve the torque performance of IPM motor. In this paper, structural optimization based on...
