| Research Abstract |
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.
