开关磁阻电机在蓄电池电机车上的应用

Application of Switched Reluctance Motors in Battery Electric Vehicles

针对目前矿用蓄电池电机车牵引动力的弊端,以四相8/6极开关磁阻电机(SRM)为研究对象,设计了一种基于TMS320F2812的蓄电池电机车SRM控制系统。介绍了SRM的原理和特点,并且设计了硬件电路。利用双闭环控制进行调速,并进行了实验。实验结果表明,SRM控制系统能使电机车运行可靠,节能效果明显。

For the drawbacks of battery electric vehicle’s traction power,four-phase 8/6 pole switched reluctance motor（SRM） is regarded as the research object,battery electric vehicle SRM control system is presented based on TMS320F2812.The principles and characteristics of SRM are described,and the hardware circuits are designed.The speed is controlled by double-loop control,then the experiment is carried out.The results show that SRM control system makes battery electric vehicles running smoothly,and the effect of energy saving is evident.
