Abstract

In motor electromagnetic noise analysis, the main focus is the radial electromagnetic force and other electromagnetic force components are ignored, which causes the analysis to be inaccurate. The electromagnetic simulation was conducted aiming at the problem to analyze the magnetic field and electromagnetic force distribution of 8-pole 24-slot permanent magnet synchronous drive motor. Radial electromagnetic force alone and radial, tangential and axial electromagnetic forces were respectively applied on the stator model of the motor in order to analyze the electromagnetic noise. The electromagnetic noise of the motor was calculated by the boundary element method, and the accuracy of the simulation analysis was verified by experiments. The parameterized structural model of the motor was established, and the influence of different stator slot widths and magnet fillet radii on radial, and tangential electromagnetic force and electromagnetic noise was analyzed. The results show that the tangential electromagnetic force has a certain effect on the electromagnetic noise, and the motor stator model loaded with radial, tangential and axial electromagnetic forces is more reliable. Reasonable reduction of stator slot width and magnet fillet radius can effectively reduce electromagnetic noise of the motor.

Key words： permanent magnet synchronous motor electromagnetic force electromagnetic noise stator slot width magnet fillet radius

基于多向电磁力的永磁同步电机电磁噪声分析

针对电机电磁噪声分析中主要关注径向电磁力而忽略电磁力分量，造成分析精度不准确的问题，对某8极24槽车用永磁同步驱动电机进行电磁仿真分析，得到电机磁场以及电磁力分布. 在电机定子模型上分别单独加载径向电磁力和综合加载径向、切向及轴向三向电磁力，对比分析电磁噪声. 采用边界元法计算电机电磁噪声，通过试验验证仿真分析的准确性. 建立电机参数化结构模型，分析不同定子槽口宽度和磁体圆角半径对径向和切向电磁力以及电磁噪声的影响. 结果表明，切向电磁力对电磁噪声有一定程度的影响，且加载径向、切向及轴向电磁力的电机定子模型更加真实可靠；合理减小定子槽宽和磁铁圆角半径可以有效降低电机电磁噪声.
