Abstract
In this paper, the problem of the ripple torque experienced with permanent magnet synchronous motors (PMSM) is discussed and solved by adopting advanced simulation tools. The two pulsating torque components are identified: the cogging (detent) torque and the slot harmonics caused ripple. Simulated results are verified by using finite element method (FEM), taking into account the nonlinearity of magnetic material and secondary effects. The results are than proved on the experimental setup. Simplified model for the torque disturbance is proposed, suitable for designing active and passive compensating measures
