本文介绍的这种电力驱动自行车,能减少环境污染,对电力来源方便的我国城市和地区,有它的现实意义。从文章内容来看,这种电机结构新颖、紧凑,它的无电刷换向原理,在其他产品中也值得借鉴。从制造成本来看,可能偏高,但大批量生产时,成本完全可以大幅度下降。文中对电气控制部分虽未详细介绍,想来不外是一套双稳态电路,由可调脉冲发生器,控制电机转速。本刊发表此文,目的是引起我国自行车制造业的注意,并希进一步作技术经济分析,来判断究竟是电动两用车还是摩托两用车更能符合国情。
The power-driven bicycle described in this paper can reduce the environmental pollution and has its practical significance for cities and areas in our country where power sources are convenient. From the article content point of view, this new motor structure, compact, brushless commutation principle, also worth learning from other products. From the manufacturing cost point of view, may be high, but the high-volume production, the cost can be substantially reduced. The text of the electrical control section, although not described in detail, wanted nothing but a bistable circuit, adjustable pulse generator, motor speed control. The publication of this article, the purpose is to arouse the attention of China’s bicycle manufacturing industry, and hope that further technical and economic analysis to determine whether it is electric dual-purpose car or motorcycle better meet the national conditions.
