开关磁阻电机（SRM）已被开发为无稀土电动机的可能候选者之一。一台样机已被制造并进行了测试。就混合动力电动汽车（2003年丰田普锐斯）中所使用的50千瓦内置式永磁同步电机而言，它在尺寸、转矩、功率和效率方面具有竞争力。研究发现，达到了50千瓦额定功率的竞争力以及95%的效率。样机提供了目标转矩的85%。除了最大转矩外，测试的开关磁阻电机覆盖了大部分的转速 - 转矩区域。对测量和计算的转矩值存在差异的原因进行了检查。尝试了一种改进设计，并设计制造了一台新的实验用开关磁阻电机用于测试。本文给出了相关结果。
A switched reluctance motor (SRM) has been developed as one of the possible candidates of rare-earth-free electric motors. A prototype machine has been built and tested. It has competitive dimensions, torque, power, and efficiency with respect to the 50-kW interior permanent magnet synchronous motor employed in the hybrid electric vehicles (Toyota Prius 2003). It is found that competitive power of 50-kW rating and efficiency of 95% are achieved. The prototype motor provided 85% of the target torque. Except the maximum torque, the most speed-torque region is found to be covered by the test SRM. The cause of discrepancy in the measured and calculated torque values is examined. An improved design is attempted, and a new experimental switched reluctance machine is designed and built for testing. The results are given in this paper.
