What is Torque Analysis in PM Synchronous Motors about?
The document analyzes torque production in permanent-magnet synchronous motors. It develops an analytical model to accurately predict cogging and commutation torques. The model considers the effect of skewing and can be used for surface-mounted and buried magnet rotor structures. Results show that skewing reduces cogging torque but increases commutation torque pulsation. The analytical method allows efficient evaluation of motor design parameters to minimize torque ripples.
