fundamental characteristics of a ferrite permanent magnet axial gap motor with segmented rotor structure for the hybrid electric vehicle
Energy Conversion Congress and Exposition, 2011Co-Authors: Shinji Chino, Satoshi Ogasawara, Takahiko Miura, Akira Chiba, Masatsugu Takemoto, Nobukazu HoshiAbstract:In newest hybrid electric vehicle (HEV) propulsion systems, permanent magnet synchronous motors (PMSMs) using high-performance rare-earth permanent magnets play an important role. However, rare earth materials employed in the high-performance rare-earth permanent magnets have problems such as price rise and Export Restriction. Thus, it is necessary to develop a rare-earth-free motor for the HEVs. In this paper, a novel ferrite permanent magnet axial gap motor with segmented rotor structure is introduced. In order to obtain the fundamental characteristics of this motor, a prototype is fabricated and tested. The experiment results of the prototype are shown in detail. It can be confirmed with the experiment results of the prototype that the proposed motor with the segmented rotor structure has the possibility of the development of the rare-earth-free motor enough.

a ferrite permanent magnet axial gap motor with segmented rotor structure for the next generation hybrid vehicle
International Conference on Electrical Machines, 2010Co-Authors: Takahiko Miura, Shinji Chino, Satoshi Ogasawara, Akira Chiba, Masatsugu Takemoto, Nobukazu HoshiAbstract:Permanent magnet synchronous motors (PMSMs) are a key part of the current hybrid electric vehicle (HEV) drive system, and the sophisticated performance such as small size, high power density, and high efficiency is required to the PMSMs in the HEV drive system. Therefore, rare earth permanent magnet is generally employed in the PMSMs in order to satisfy those demands. However, rare earth materials contained in the rare earth permanent magnet have several concerns caused by uneven distribution, because the rare earth materials such as neodymium and dysprosium depend on China for 90% or more of the world share. Accordingly, the rare earth materials have the undeniable possibility of sudden rise of price or reinforcement of Export Restriction. On the other hand, the HEVs tend to be promoted rapidly because of growing concern about environmental problems. Therefore, it is very important to develop rare-earth-free motors for the next generation HEV drive system. This paper proposes a ferrite permanent magnet axial gap motor without the rare earth materials for the HEVs. In addition, the proposed motor structure and the analytical results with the 3D-FEA are introduced.
