基于变极绕组的异步起动永磁同步电动机起动性能研究
Research on Starting Performance of Line-Start Permanent Magnet Synchronous Motor Based on Pole Changing Winding
摘要
Abstract
Line-start permanent magnet synchronous motors (LSPMSMs) have superior performance with respect to induction motors in many applications due to their high efficiency,improved power factor and enhanced torque density.But poor starting torque and synchronization capability,which restrict the motors' applications,are the two serious shortcomings of these LSPMSMs.This paper presented a pole changing LSPMSM with a novel 6/8 pole changing stator winding.The operating principle of the 6/8 pole changing LSPMSM was analyzed and compared to the conventional 8-pole LSPMSM.Then the comparisons of braking torque,pulsating torque,no-load back electromotive force (EMF),and locked torque between the proposed motor and conventional LSPMSM were studied by using two-dimensional finite element method (FEM).The simulation and experimental results show that the braking and pulsating torques are suppressed fundamentally by using the 6/8 pole changing starting method,and meanwhile,the starting capability gets improved effectively.关键词
