针对在装甲车辆中体积、功率受限条件下，永磁电动机提升低速转矩与拓宽弱磁工作范围难以兼顾的问题，提出了采用电动机绕组换接的方法。提出了一种切换电路的设计方案，采用电路仿真软件Muhisim分析了切换电路的动态工作过程。在此基础上，构建了一套适用于三相绕组切换的零电流切换控制系统，可通过上位机观测电路中的电流波形，并实现对绕组的串、并联结构进行切换控制。试验结果表明：该电路可快速实现绕组的串／并联切换，而且基本上不会产生电压冲击。

Under the circumstances that volume and power are limited in armored vehicles, raising low speed large torque and widening flux-weakening range become conflict inevitably in permanent magnet motors. The motor winding switching method is adopted to resolve this problem. A switching circuit design is proposed and the dynamic process of switching circuit is analyzed with Muhisim software. What' s more, a switching control system is constructed based on zero current switching to fulfill triphase winding switching and observe the current waveforms. The experimental results show that the switching between serial and parallel connection in the circuit is very rapid and the voltage impulsion is eliminated during the switching process.
