Abstract

It is significant to balances torque and vibration performance for the surface-mounted permanent magnet (PM) machines. This paper proposes a functional magnet structure to suppress the vibration response of integral-slot surface-mounted PM machines. At the same time, the torque ripple is also greatly reduced without sacrificing the average torque. Firstly, taking the 48-slot/8-pole PM machine as an example, the main sources of the air-gap radial force are analyzed based on the Maxwell stress equation. Thereby, the main PM flux density harmonic components that contribute to the radial force are pointed out. Secondly, the design method of different functional magnet structure is investigated. Then, the effects of different magnet shapes on the torque and vibration performances are compared. The result shows that the proposed sinusoidal+3rd-order harmonic injection functional magnet structure can effectively improve the vibration performance without sacrificing the average torque. Finally, the prototype of the 48-slot/8-pole PM with functional magnet structure is manufactured, and the experiments are carried out for validation.

利用功能磁体结构分析和减少整体槽永磁机的电磁振动

平衡表面贴装永磁（PM）机器的扭矩和振动性能意义重大。本文提出了一种功能性磁体结构，用于抑制整体槽表面贴装式永磁电机的振动响应。同时，在不牺牲平均转矩的情况下，还大大降低了转矩纹波。首先，以 48 槽/8 极永磁机为例，根据麦克斯韦应力方程分析了气隙径向力的主要来源。由此，指出了造成径向力的主要永磁磁通密度谐波成分。其次，研究了不同功能磁体结构的设计方法。然后，比较了不同磁体形状对扭矩和振动性能的影响。结果表明，所提出的正弦+3 次谐波注入功能磁体结构可以在不牺牲平均扭矩的情况下有效改善振动性能。最后，制造了带有功能磁体结构的 48 槽/8 极永磁发电机原型，并进行了实验验证。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
