Development of dual-rotor-type permanent magnet reluctance generator adapting for car

2010年，对一台双转子永磁磁阻发电机的特性进行了有限元分析。结果是，当内外转子的相角相差180电度时，由于消除了两个转子转矩的谐波含量，齿槽转矩降低了一半。然而，输出功率并没有得到改善。2011年，为了建立由永磁同步发电机和磁力齿轮相结合的紧凑型高功率发电系统，设计了高性能磁力齿轮。结果表明，采用极各向异性粘结磁体的磁齿轮具有良好的性能。

In 2010, characteristics of a dual-rotor-type permanent magnet reluctance generator (PMRG)are examined by using finite element method (FEM). As a result, cogging torque is reduced to half since harmonic contents of torque of both rotors are canceled when inside and outside rotors have differential phase angle of 180 electrical degrees each other. However, output power was not improved. In 2011, to establish the compact and high power generation system comprising a combination of the PMRG and a magnetic gear, the high performance magnetic gear is designed. As a results, it was clear that the magnetic gear used a polar-anisotropic bonded magnet has desirable features.
