在排气、噪音等公害以及节能等问题已开始引人注目的今天,在未来城市的交通系统和运行控制的自动化方面,人们对电动汽车寄予很大希望。就电动汽车而言,它一方面受动力源电池的限制,另一方面它在起动和高速运行时,仍以只输出某一转矩的直流电机驱动,同时还采用无级变速之故,停车时再起动就产生动力不足的现象。 本文介绍的并不是把直流电机作为变速机,而把它作为额定转速转动的原动机。在变
Nowadays, when the problems of pollution such as exhaust gas, noise and energy saving have started to attract attention, people have great hopes for electric vehicles in the future automation of urban transportation system and operation control. On the electric car, it is limited by the power source battery on the one hand, on the other hand it is still in the start-up and high-speed operation, still only output a certain torque of the DC motor drive, but also the use of CVT, parking When the start again to produce power shortage phenomenon. This article describes the DC motor is not as a variable speed, but as the rated speed of the prime mover rotation. Changing
