摘要

本文对变速感应电动机的电磁力进行了研究。首先分析了异步电动机在非正弦电源下的电磁力。提出的径向电磁力数学模型考虑了电压源逆变电源的高时间谐波。然后在分析电磁力谱含量的基础上，提出了感应电机驱动的磁场定向控制方案。该方案的一个显著特点是通过转子磁链优化使任意工作点的径向电磁力最小化。通过Matlab仿真对该方案进行了实验验证，结果表明与传统的磁场定向控制相比，径向电磁力有所降低。

Magnetic noise reduction in field oriented controlled induction machine

This paper presents electromagnetic forces investigation of variable speed induction motor. Initially electromagnetic forces of induction motor at nonsinusoidal power supply are analyzed. Proposed radial electromagnetic forces math model allows to take into account higher time harmonics of voltage source inverter supply. Then based on analysis of electromagnetic forces spectral content field oriented control scheme of induction motor drive is proposed. A distinctive feature of this scheme is radial electromagnetic forces minimization at any operating point by rotor flux optimization. Experimental examination of proposed scheme by emulating in Matlab shows reducing of radial electromagnetic forces versus conventional field oriented control.
