基于非气隙侧调制的永磁电机绕组因数提升机理
Mechanism of Winding Factor Enhancement Permanent Magnet Motor Based on Non-air-gap Side Modulation
摘要
Abstract
Magnetic field modulation motors have attracted widespread attention due to their high torque density.In this article,a 12-slot,19-pair pole conventional magnetic field modulation motor is first studied.The influence of modular stators on the winding factor is discussed.The results indicate that placing the flux gaps on the winding teeth leads to a change in the original magnetic motive force of the winding,thereby leading to variation in the wingding factor.By deducing the variation of modular angle on the pitch factor of working harmonics,a winding-factor-enhanced modular motor is proposed.Second,based on the energy method,the harmonic contributions of the winding-factor-enhancing motor and conventional motor are analyzed,compared,and verified by finite element analysis.Results have shown that the winding-factor-enhanced motor improved the winding factor of working harmonics,resulting in an increase in torque.Finally,a prototype is built and the reasonableness of analytical calculation and finite element simulation is verified though experiments.关键词
