Considerable vibration and acoustic noise limit the further application of Switched Reluctance Machine (SRM) due to its structural characteristics and working principle. An improved SRM model with double auxiliary slots (DAS) was proposed, in which the direction of the magnetic line of force was adjusted, and the radial magnetic density in the air gap was reduced by changing the local tooth profiles of the stator and the rotor. The effects of initial rotor position and turn-on angle and turn-off angle on radial Electromagnetic Force (EMF) and maximum torque were investigated. The results indicate the radial EMF and torque increase significantly with the advancement of the turn-on angle or the delay of the turn-off angle. In the orthogonal experimental design, initial rotor position, turn-on angle, and turn-off angle were taken as the factors, and the optimal set of parameters that minimized radial EMF was determined according to a greater output torque. In contrast to conventional SRM, the radial EMF of the SRM with DAS significantly reduces when the optimal set is applied.

一种改进的双辅助槽开关磁阻电机振动性能的数值研究

由于其结构特点和工作原理，相当大的振动和噪声限制了开关磁阻电机（SRM）的进一步应用。提出了一种改进的双辅助槽（DAS）SRM模型，通过调整磁力线方向，通过改变定转子局部齿廓来降低气隙中的径向磁密度. 研究了初始转子位置和开启角度和关闭角度对径向电磁力 (EMF) 和最大扭矩的影响。结果表明，径向电动势和扭矩随着开启角的提前或关闭角的延迟而显着增加。在正交实验设计中，以转子初始位置、开启角度和关闭角度为因素，最小化径向电动势的最佳参数集是根据更大的输出扭矩确定的。与传统的 SRM 相比，采用 DAS 的 SRM 的径向 EMF 在应用最优组时显着降低。
