永磁直流无刷轮毂电机控制设计开发与应用研究
Research on Control Design Development and Application of Permanent Magnet DC Brushless Hub Motor

气候变暖、能源危机已成为21世纪人类所面临的共同挑战，而研究具有节能环保特点的电动自行车成为解决这些问题的重要途径。作为电动自行车核心的轮毂电动机，其性能的好坏对整车功能的实现有决定性作用。轻型电动自行车，其动力源以永磁直流无刷电机为主，本文设计一款24 V，430 W的永磁直流无刷电机，首先设定规格需求，并说明设计的方法及程序，依此进行电机设计及电磁场分析，分析工作完成后，再进行机械设计与制作，最后，通过一种动力测试设备并完成测试及验证的工作。
Climate warming and energy crisis have become common challenges facing mankind in the 21st century, and research on electric bicycles with energy-saving and environmentally friendly characteristics has become an important way to solve these problems. As the core of the electric bicycle, the performance of the hub motor has a decisive effect on the realization of the function of the whole vehicle. Light-duty electric bicycles are mainly powered by permanent magnet brushless DC motors. This article designs a 24 V, 430 W permanent magnet brushless DC motor. First, set the specifications and requirements, and explain the design methods and procedures, and then proceed with the motor design and electromagnetic field analysis. After the analysis is completed, mechanical design and production are carried out. Finally, the power test equipment is constructed and the test and verification work is completed.
