作者对SR发电机进行了具有竞争力的外形尺寸、重量、最大功率和效率设计。然而，SR和IPM发电机的效率图是不同的。因此，很难进行直接比较。本文对设计的两种SR发电机和一种IPM发电机在混合动力汽车上的应用进行了能效比较。发现SR发电机的能量效率与IPM发电机的能量效率相当或更好，因为SR发电机在空转时没有铁损失，而IPM发电机存在永磁体造成的铁损失。
The SR generator has been designed with competitive outer dimensions, weight, maximum power and efficiency by the authors. However, efficiency maps of the SR and IPM generators are different. Thus, direct comparison has been difficult. In this paper, a comparison of energy efficiency among two designed SR generators and an IPM generator is carried out for the application for hybrid electric vehicles. It is found that energy efficiency of the SR generator is competitive or better than that of the IPM generator because the SR generator has no iron loss during idling although iron loss exists in IPM generators caused by permanent magnets.
