摘要

电气化正在汽车和建筑机械等不同领域取得进展。用于电动系统的电机要求结构紧凑、功率密度高。在这项研究中,我们通过减少应力集中,开发了一种转速为 22,000 r/min 的小型电机。每个磁极在圆周方向上有三块磁铁,磁铁呈 U 形排列。磁铁插入槽由内径一侧的膨胀磁通屏障和无导向结构组成。磁铁插槽可减少应力集中。此外,转子的外径表面有两个凹痕,外径一侧有膨胀磁通势垒。凹痕在北极(N)和南极(S)之间形状不同。这些结构减少了扭矩波纹。

Development of low-torque-ripple motor with high rotational speed to downsize electrical systems

Electrification is progressing across different fields such as automobiles and construction machinery. Motors for electric systems are required to be compact and achieve high power density. In this study, we developed a small motor with rotation speed of 22,000 r/min by reducing stress concentration. Each pole has three magnets in the circumferential direction, and the magnets are arranged in a U-shape. The magnet insert slots are comprised of expanded flux barriers on the inner diameter side and a guide-less structure. The magnet slots reduce stress concentration. Additionally, the rotor has two dents on the outer diameter surface and expanded flux barriers on the outer diameter side. The dents have different shapes between the North (N) and South (S) poles. The structures reduce the torque ripple.
