Magnetic Circuit Modeling and Experimental Study of Torque Motors Considering Variation of Working Air Gap Flux Leakage Ratio
摘要
Abstract
Aiming at the deficiency of the traditional magnetic circuit modeling of torque motors using fixed flux leakage ratio to describe the working air gap flux leakage,in this paper,considering the variation of the working air gap flux leakage ratio with the geometry of magnetic circuit,equaling the magnetic flux leakage to the reluctance in parallel,the magnetic flux leakage equivalent reluctance model of torque motor is established,and the relationship between the flux leakage ratio of working air gap and the length of air gap is given.The finite element analysis and experiments were carried out,and compared with the traditional model.The results show that the maximum error of the traditional model is up to 24％,and the maximum error of the magnetic flux leakage equivalent reluctance model in this study is only 6％.The magnetic flux leakage equivalent reluctance model is more accurate than the traditional model,which lays a foundation for the accurate analysis and prediction of torque motor performance.关键词
