电动汽车系统中电机驱动的优势与劣势的对比

基于电动汽车的特点，对所采用的电机也有较高的要求。为了提升最高时速，电机应有较高的瞬时功率和功率密度(W/kg)；为了增加1次充电行驶距离，电机应有较高的效率；而且电动汽车是变速工作的，所以电机应有较高的高低速综合效率；此外有很强的过载能力、大的启动转矩、转矩响应要快。电动车起动和爬坡时速度较低，但要求力矩较大；正常运行时需要的力矩较小，而速度很高。低速时为恒转矩特性，高速时为恒功率特性，且电动...[详细]
氙气灯和卤素灯的区别

　　氙气灯与卤素灯的区别主要如下：　　1、氙气灯是靠高压电弧放电来照明的，所以氙气灯需要在灯泡之外配备额外的电子控制启动装置，俗称安定器，因为点亮氙气灯需要2.3万伏的启动电压，而普通车用卤素灯只需要12伏的工作电压安定器作为灯泡之外的一个独立部件，对整套氙气灯的可靠性产生重要影响，此外，安定器作为一种高压电器装置，其自身的安全性也非常重要。　　2、如果只改装氙气灯泡却不相应地更换灯具，则并...[详细]
