摘要

轻型电动汽车(LEV)已成为我们日常生活中不可或缺的一部分。轮内无刷直流电机(BLDCM)是轻型电动车推进系统的首选。电机中使用的铁磁材料与几何设计参数一样会影响电机的输出性能。本研究的主要目的是调查振动对 LEV 驱动性能的影响及其对 BLDCM 的破坏性影响。振动效应会缩短电机的运行寿命并导致其故障。本研究分析了不同定子和转子铁磁材料在 LEV 的轮式 BLDCM 中的振动效应。结果表明,永磁体和低碳钢铁磁材料是影响 BLDCM 运行性能的因素。在 ANSYS Workbench 软件下进行了总变形谐波响应分析,以揭示特定轮内 BLDCM 的振动效应。当转子使用 SmCo5(R18) 磁体,定子使用 M22-26G 低碳钢铁磁材料时,振动影响最小,转子的最大振动为 0.086023 μm,定子的最大振动为 18.386 μm。由此得出结论,最兼容的材料可使 BLDCM 的振动值最小。

Effect of Ferromagnetic Materials on Vibration of In-wheel Brushless Direct Current Motor for Light Electric Vehicle

Effect of Ferromagnetic Materials on Vibration of In-wheel Brushless Direct Current Motor for Light Electric Vehicle

Light electric vehicles (LEV) have become an integral part of our daily lives. In-wheel Brushless Direct Current Motor (BLDCM) is mostly preferred in the propulsion systems of LEVs. Ferromagnetic materials used in electric motors affect motor output performance as much as geometric design parameters. The main objective of this study is to investigate the effects of vibration on the driving performance of LEVs and its disruptive effects on BLDCM. Vibration effect reduces the operating life of electric motors and leads to their malfunction. In this study, the vibration effects of different stator and rotor ferromagnetic materials in-wheel BLDCM of LEVs were analyzed. It has been revealed that permanent magnets and mild steel ferromagnetic materials are factors affecting the operating performance of BLDCM. Total deformation harmonic response analyses were performed under ANSYS Workbench software to reveal the vibration effects on the specified in-wheel BLDCM. The lowest vibration effect is achieved when SmCo5(R18) magnet is used in the rotor and M22-26G mild steel ferromagnetic material is used in the stator, where the maximum vibration of 0.086023 μm in rotor and 18.386 μm in stator are achieved. It was concluded that the most compatible materials result in the lowest vibration values in BLDCM.
