由于电机设计是电动汽车 (EV) 和混合动力电动汽车 (HEV) 开发的关键，因此它最近已成为人们广泛关注的主题。内置式永磁 (IPM) 电机受益于永磁 (PM) 扭矩和磁阻扭矩，具有高扭矩密度和高效率等优点。然而，IPM电机的一个明显缺点是高速运行时难以实现所需的弱磁能力和低振动。本研究的重点是优化电动汽车 IPM 电机的弱磁性能并减少振动。首先，基于数学模型对弱磁能力、齿槽转矩、转矩脉动和径向振动力进行了分析。其次，通过遗传算法对三种电机进行优化和分析，直观地了解不同转子结构对扭矩特性、效率和扩展速度范围的贡献。第三，提出了开槽转子结构以减少扭矩脉动和径向振动力。讨论了磁通密度分布，解释了转子开槽和定子斜槽电机具有较小的转矩脉动和径向振动力的原理。最后，通过实验验证了设计和优化结果。
As motor design is key to the development of electric vehicles (EVs) and hybrid EVs (HEVs), it has recently become the subject of considerable interest. Interior permanent magnet (IPM) motors offer advantages such as high torque density and high efficiency, benefiting from both permanent magnet (PM) torque and reluctance torque. However an obvious disadvantage of IPM motors is that operation at high speed involves difficulties in achieving the required flux-weakening capability and low vibration. This study focuses on optimizing the flux-weakening performance and reducing the vibration of an IPM motor for EVs. Firstly, flux-weakening capability, cogging torque, torque ripple, and radical vibration force are analyzed based on the mathematical model. Secondly, three kinds of motors are optimized by the genetic algorithm and analyzed, providing visible insights into the contribution of different rotor structures to the torque characteristics, efficiency, and extended speed range. Thirdly, a slotted rotor configuration is proposed to reduce the torque ripple and radical vibration force. The flux density distributions are discussed, explaining the principle that motors with slotted rotors and stator skew slots have smaller torque ripple and radical vibration force. Lastly, the design and optimization results have been validated against experiments.
