Abstract
Technique of Step-skewing of rotor (SSR) is much efficient to reduce the harmonics of Back EMF, minimize cogging torque and torque ripple. In EV & HEV applications, it can conspicuously increase the torque control precision, decrease torque ripple, thus improve the vehicle comfort. This paper analyzed the no-load and load performance of motor with step-skewed rotor and another with slot-skewed stator. Through comparing the performance of each motor, this paper revealed the advantage of step-skew technique. The conclusion is verified by FEA and experiment. Copyright form of EVS25.
