摘　　要：介绍一种轨道车辆牵引用永磁同步电动机转子位置的检测方法。该方法利用数字转换器AD2S1200实现旋转变压器的模拟输出信号到数字信号的转换。设计了AD2S1200与旋转变压器和TMS320F2812之间的接口电路,针对实际应用中出现的问题,重点阐述了转子位置信号的数字处理方法。试验表明,该方案能够很好地实现电机转子位置的检测,系统运行良好。A method of rotor position detection in the PMSM used for driving the rail vehicle was presented, which transformed analog signals of resolver to digital signals using the resolver digital converter（RDC） AD2S1200. The interface circuit for RDC and resolver and that for AD2S1200 and TMS320F2812 were designed. Finally methods of processing position signals were presented emphatically aimed at problems in application. Experiment results showed that methods of detection and signal processing measured the rotor position with high performance, which made the whole system go well.
