摘要
开关磁阻电机具有很强的容错能力,但这种能力也是有限的。在开关磁阻电机绕组短路的情况下对开关磁阻电机容错能力进行深入的研究。通过建模和测试,针对以下两种情况进行了理论分析和实验:一种是相极问绕组完全短路,另一种是相极间绕组部分短路。实验证明相绕组短路导致转矩减少,为了弥补转矩的减少,绕组电流就要增加;在相绕组部分短路的情况下,对输出总转矩的影响可以忽略。
The switched reluctance motor is known to the fault tolerant, but it is not fault free. An in-depth look at winding short circuits in this particular machine was taken. Modeling and testing complement a theoretical analysis, two cases need to be distinguish, one where a complete pole is shorted, and one where a few turns are shorted. Pole short circuits lead to torque reduction that can be easily compensated for with increased cur- rent. With few turns shorted, the impact on overall torque may actually be negligible.
