电动车作为日本铁道车辆的代表之一,通过外部集电获取的电能来驱动电动机实现走行。1990年以后制造的电动车以制动时的电力再生功能为标准装备。为了控制车辆的速度,调整电动机上的电压和电流,使作用在车轮上的驱动力产生变化,进行加速减速。随着时代的发展,根据电动机的种类和性质,控制力和速度的方法以及电动车控制技术的装备均发生了一些变化。 Electric cars as one of the representatives of the Japanese railway vehicles, through the external power harvesting to drive the motor to achieve the move. Electric cars manufactured after 1990 are equipped with the power regeneration function when braking. In order to control the speed of the vehicle, the voltage and the current on the motor are adjusted so that the driving force acting on the wheel changes and the deceleration is accelerated. With the development of the times, some changes have taken place in the methods of control and speed and the control technology of electric vehicles according to the type and nature of the motor.
