摘　　要：开关磁阻电机(Switched reluctance machine,SRM)凭借结构简单、可靠性高、起动转矩大、起动电流小等内在优势,正得到越来越广泛的关注。另一方面,随着能源危机与环境问题的加剧,采用电能作为动力的交通工具是各国的研究热点。而在中国,研究适合国情,且具有高性价比的纯电动自行车具有巨大的现实意义与示范价值。本文研究了一种应用于电动自行车的三相12/16开关磁阻轮毂电机系统,经过理论分析确定电机结构,进一步利用有限元软件完成样机设计,详细叙述了电机的设计方法,讨论了绕组方案对电机性能的影响,最终试制了样机。利用基于ARM芯片制作的专用控制器完成了对该电机性能的初步验证。The switched reluctance machine （SRM） has attracted increasing attentions in recent years due to its inherent simplicity, robustness, reliability and high starting torque. Meanwhile, with the aggra- vation of the energy dilemma and environment contamination, the research on electric vehicles is becom- ing the focus in a large number of counties. In China, the study on electric bicycle, which possesses high performance-price ratio and suits characteristic conditions, absolutely contains remarkable values. Here, an in-wheel three-phase 12/16 SRM-based drive system is investigated for electric bicycle. Firstly, the structure of the SRM is discussed and the prototype is designed based on finite element analysis. Then, the detailed design process of SRM is described. Also, the influence of winding configuration on the electromagnetic performance is discussed. Finally, mental test is conducted based on an ARM-based a 350 W prototype is manufactured and the experi- controller. The measured results verify the perform-ance of the SRM.
