摘要

感应电机铁心电磁应力主要来源于硅钢片的磁致伸缩以及定转子间麦克斯韦电磁应力,在正弦及谐波激励下,硅钢片均具有较强的磁各向异性。因此,为了准确计算电机铁心电磁应力,在该文首先对无取向硅钢片在正弦及谐波激励下的磁化和磁致伸缩特性曲线进行测试;然后,建立考虑磁化及磁致伸缩特性各向异性的感应电机电磁-机械耦合振动模型,并计算电机铁心电磁应力分布;最后,通过对比有无考虑磁各向异性的电机模型计算结果,分析电机铁心的应力分布的各向异性,同时,计算了5次谐波和7次谐波注入下电机定子铁心电磁应力曲线及频谱,发现在100 Hz和200 Hz频率时,谐波对应力幅值的影响较大。

Abstract：

Induction motor cores generate large vibration and noise because of the Maxwell electromagnetic stress between the stator and the rotor as well as the magnetostrictive stress of silicon steel. The non-oriented silicon steels in motor cores show remarkably anisotropic magnetic and magnetostrictive properties under sinusoidal and harmonic excitations. Thus, in order to compute motor stress accurately, this paper tests the anisotropic magnetic and magnetostrictive properties of silicon steel under sinusoidal and harmonic excitations. Then, an electromagneto-mechanical coupled model for motors considering anisotropic magnetic and magnetostrictive properties is proposed and stress distribution of motor cores is calculated. Finally, by comparing the model with and without considering the magnetic anisotropy, the stress distribution of anisotropy is analyzed. From the stress curve and spectrum under the harmonic excitation, it can be seen that the influence of harmonic on stress is obvious at 100 Hz and 200 Hz.
