Abstract

This research is carried out related to the winding design of a BLDC motor for electric bicycles. Using a Bafang BLDC hub motor as a reference motor, which has 18 slot-20 pole configurations, a reverse-engineering process is carried out to obtain a more optimal design. An analysis is done related to the effect of each winding parameter on motor performance. Based on this analysis and the criteria for e-bike BLDC, a winding design is proposed. The design criteria for electric bicycles BLDC are determined by the needs of the rider, government regulations, and physical limitations. The proposed design is compared with the reference design regarding its performance. Finally, an analysis of the magnetic flux distribution was carried out for the proposed design. Based on the experiment, it was found that the proposed design has better performance than the reference design. It was found that the proposed design has the ability to generate 250 watts of constant power for a wider speed range and has higher efficiency.

城市电动自行车用250瓦外转子无刷直流电机性能分析与设计

本文针对电动自行车用无刷直流电机的绕组设计进行了研究。以巴方无刷直流轮毂电机为参考电机，采用18槽-20极配置，进行逆向工程，得到更优的设计方案。分析了各绕组参数对电机性能的影响。在此基础上，结合电动自行车无刷直流电机的设计准则，提出了一种绕组设计方法。电动自行车BLDC的设计标准由骑行者的需求、政府法规和物理限制决定。并与参考设计进行了性能比较。最后，对所提出的设计进行了磁通分布分析。实验结果表明，本文提出的设计方案比参考设计方案具有更好的性能。结果表明，所提出的设计能够在更宽的速度范围内产生250瓦的恒定功率，并且具有更高的效率。
