分数槽永磁同步电机电磁振动的分析与抑制
Electromagnetic Vibration Analysis and Suppression of Permanent Magnet Synchronous Motor With Fractional Slot Combination
摘要
Abstract
In the permanent magnet synchronous motors with fractional slot combination, the electromagnetic vibration is generally larger than that of integer slot combination motors, because its force harmonic with the lowest mode number have a major impact on electromagnetic vibration. In the paper, a method, eliminating the harmonic with the lowest mode number, was proposed for suppressing electromagnetic vibration. The 2D finite element method was adopted to analyze electromagnetic force distribution and electromagnetic vibration of two motors with 12-slot 8-pole and 24-slot 8-pole respectively. It was illustrated that the proposed method was suitable to the fractional slot motor while not to the integer slot motor. A rig for the 12-slot 8-pole motor was built for test. The validity of the proposed method is confirmed by both simulated and experimental results.关键词
