混合励磁磁通切换电机等效磁路模型
Equivalent Magnetic Circuit Model of Flux-switching Hybrid Excitation Machine
摘要
Abstract
Flux-switching hybrid excitation machine（FSHM） was an interesting brushless machine with magnets in the stator,which offered the advantages of bipolar flux linkage,simple and robust rotor structure and high power density.Adjustment and control of the PM air gap magnetic field could be achieved by means of controlling the field winding current,and magnetic bridge amplified the effect of field flux on PM flux.This paper took equivalent magnetic circuit model（EMCM） of maximum phase flux-linkage position as point of penetration,deduced the equation of peak magnetic flux,and explored a method for estimating the relative permeability of magnetic bridge.The characteristic relation between the thickness of magnetic bridge and initial air gap flux density,magnetic bridge flux density,regulating capacity of air gap magnetic field,and magnetic lines transfer were studied combined with finite element analysis（FEA）.The estimation results based on EMCM agreed well with the FEA and experiment data,which confirmed the correctness of modeling method and theoretical analysis.It provided reference for FSHM design and performance analysis.关键词
