| Abstract: | This paper analyzes the influence of stator skewed-slot on PM synchronous motor from two aspects of cogging torque and electromagnetic torque. PM synchronous motor with straight slot is compared with skewed slot by 2D finite-element subsection method. The influence of various skewed-slot structures on tooth harmonic, starting performance and pulsating torque of PM synchronous motor are analyzed also. |
