摘要
本文对一种绕组按N,S交替排列的开关磁阻电动机原型进行了四个典型的物理模型的有限元分析;提供了11种不同定、转子相对位置的磁链φ与电流i之关系图及等矢量磁位线分布图,给出了给定激磁电流条件下的转矩T与转子位置θ的变化曲线T=f(θ)及电,感L与电流i、转子位置θ的变化曲线L=f(i,θ)。文中还进行了计算与实验结果的对比。
The results of two-dimensional finite-element analysis of the field distribution of a doubly salient switched reluctance motor are reported. The stator winding is connected to the N-S polarity arranged alternately along the inner periphery of the stator.Four models have been chosen for the calculation and magnetic field distribution in 11 different but typical cases with various current excitations of the stator windings and in different rotor positions as well as the flux linkage of the winding, the terminal inductance per phase, are calculated. The average torque developed is also calculated under forced current feed conditions.Calculated results are found to agree well with those obtained by measurement.
