Torque Ripple Minimization in PM Synchronous Motors Using Tooth Shape Optimization

Several approaches are available to reduce pulsating torque components in permanent magnet motors. One of the known techniques is stator tooth shape modifications. This paper presents an integrated algorithm applicable for tooth shape optimization of permanent magnet motors. This method focuses on the reduced basis technique, finite element analysis and Taguchi method and is conducted on tooth shape optimization of a 3-phases radial flux PMSM motor.
