摘要
为研究8/6极开关磁阻电动机转矩输出特性,阐述了开关磁阻电动机单相励磁原理,利用Maxwell 2D有限元软件分析了电动机齿极间气隙处磁路分布,并提出了一种适用于8/6极开关磁阻电动机的新型椭圆磁路模型;在该模型基础上求解气隙磁导,得到了电动机处于平衡位置时的转矩数学模型;最后,通过有限元仿真结果证明了转矩数学模型的正确性。
To study output torque characteristics of 8/6 switched reluctance motor,the principle of single-phase excitation of switched reluctance motor was expounded,and the magnetic field distribution in air gap between motor teeth was analyzed by finite-element analysis software Maxwell 2D.A new model of elliptic magnetic paths was established which can describe the elliptic magnetic paths of 8/6switched reluctance motor.The air gap permeance was solved based on the model and the mathematic model of torque was derived when the motor stays balanced.Finally,the validity of mathematic model was certified by the results of finite-element analysis.
