High Performance Ferrite Magnet Motor Developed - No Rare-Earth Required

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.
