摘要

径向力对开关磁阻电机的振动和噪声有独特的影响，限制了开关磁阻电机的应用。定子顶部的矩形槽可以减小径向力，将原有的单向径向磁通密度分量分解为径向和切向磁通密度分量。本文将开槽前后的气隙磁场划分为4个区域，其中磁场线分别采用抛物线型和直线模拟。采用理论计算和有限元分析相结合的方法，分析了定子槽对SRM径向力、转矩脉动和平均转矩的影响。结果表明，槽形结构能有效抑制径向力，且抑制程度受槽形宽度的影响，平均转矩随定子顶部开槽而略有减小。

Inhibitory Effect of Radial Force to Switched Reluctance Motor with Stator Pole Slot

The radial force has a unique impact on vibration and noise to Switched Reluctance Motor (SRM) which limit its application. The rectangular slot on the top of stator can decrease the radial force where the original unidirectional radial flux density component is decomposed into radial and tangential ones. The air-gap magnetic field is divided 4 regions before and after slotting in this paper, where magnetic field line is simulated with the parabola type and straight line. The influence of the stator slot on radial force, torque ripple and average torque of SRM is analyzed by means of theoretical calculation and the Finite Element Method (FEM). It is proved that the slotted structure can effectively suppress radial force and that the degree of inhibition is affected by the slot width while the average torque slightly decreases with slot on the top of stator.
