摘　　要：针对8/6极开关磁阻电机的一种新型双极性励磁方式进行了仿真研究,给出了与传统励磁方式下的磁场分布的对比,表明双极性励磁的特点是开关磁阻电机的转矩脉动更小、效率更高。搭建了以TMS320F2812为控制器的8/6极开关磁阻电机实验装置,通过实验验证了8/6极开关磁阻电机双极性励磁策略的可行性。A new bipolar excitation of 8/6 pole switched reluctance machines （SRNI） is simulated. The magnetic pattern of bipolar excitation is compared with conventional excitation. The result shows that 8/6 switched reluctance machines with bipolar excitation has less torque pulsation and higher e^ciency. Hardware of controller is built based on TMS320F2812 and the experiment verifies bipolar excitation is feasible.
