摘　　要：针对传统力矩马达磁路建模以定漏磁系数描述工作气隙漏磁的不足,考虑工作气隙漏磁系数随磁路几何形状变化,将磁路漏磁等效为并联磁阻,建立了力矩马达磁路漏磁等效磁阻模型,并得到了工作气隙漏磁系数随气隙长度变化关系式。开展有限元仿真与试验验证,并与传统模型对比求解,结果表明:传统模型最大求解误差为24%,漏磁等效磁阻模型最大求解误差仅为6%,漏磁等效磁阻模型具有更高的准确度,为开展力矩马达性能精确分析与预测奠定了基础。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.
