Designing electro magnetic motor skew structure and method to skew analysis using FEM

Abstract

In these days, importance of motor increase, As increasing of importance, there are many studies on increasing accuracy of controlling motor. Torque ripple is disturbance of torque control. There are many ways to reduce torque ripple and Skew analysis is widely used. This paper shows how to modeling Skew rotor and torque result of skew rotor.
