摘要
噪声是开关磁阻电机的主要缺点，准确计算定子固有频率对低噪声电机设计和噪声控制有十分重要的意义。本文基于能量法，提出了一种计算开关磁阻电机定子固有频率的方法，分析中考虑了弯曲、剪切和拉伸应变能及旋转动能和平移动能，并给出了计算结果与实验结果的比较，两者具有良好的一致性。
Acoustic noise is the major drawback of switched reluctance motors.It is very important for the design of a low noise motor and the reduction of acoustic nosie to determine natural frequencies of stators accurately.This paper presents a method of calculating the frequencies based on energy principle,taking into account bending,shear and extensional strain energies and translational and rotatory kinetic energies.Analytical results are compared with experimental results,and good agreement is obtained.
