New Energy and Industrial Technology Development Organization (NEDO) has announced that the organization, working together with a group of School of Information Science, Hokkaido University, successfully developed a newly structured rotor segment type of axial-gap motor for use of hybrid electric vehicles (HEV).
The output performance of the new motor is comparable with the conventional rare-earth magnet motor although its magnetic material consists of ferrite magnets only without using any rare earth. A result of actual load testing under a constant torque range shows 51.5KW which is equivalent to conventional HEV battery performance.
This technology has been developed as a part of "technology development for the next generation high performance automobile battery systems ".
The new technology has strong potential to relieve auto-manufacturers from extremely competitive situation in procurement of the rare-earth material which is supposed to be essential for the next generation vehicle development.
