目前电动自行车的动力驱动主要是轮毂式无刷直流电动机。电动自行车控制器作为电动自行车的控制核心,是电动自行车的关键部件,与无刷直流电动机一起构成电动自行车的动力驱动系统。为了提高电动自行车的的骑行舒适性、安全性,本文对电动自行车的动力驱动系统进行了深入的研究,并简要介绍了电动自行车控制器的功能构成和软硬件设计。 At present, the main power-driven electric bike wheel hub brushless DC motor. As the control core of electric bicycle, electric bicycle controller is a key component of electric bicycle, and forms a power-driven system of electric bicycle together with brushless DC motor. In order to improve ride comfort and safety of electric bicycles, this paper deeply studies the power-driven system of electric bicycles, and briefly introduces the functional composition and hardware and software design of the electric bicycle controller.
