Mass production of "amorphous laminated core" for high-efficiency motors

 Next Core Technologies Co., Ltd. (Uji City, Kyoto Prefecture, Representative Director: Yuki Yamamoto), which promotes the development of next-generation high-efficiency motors, has recently announced the development of “amorphous multilayer For the first time in the world (according to our own research), we have set a target for mass production of "Core".


By using the newly developed amorphous laminated core, it has been confirmed that motor efficiency is improved by up to 10% compared to existing motors using magnetic steel sheet cores, and the world's highest level of output density in the 5kW class is 1.2kW/ kg, motor efficiency of 95% was achieved.


 In the future, it will be installed in EVs and air conditioners that require small size and high speed rotation, and it is expected that it will contribute to the realization of carbon neutrality.



In the future, we plan to seek partner companies to jointly develop next-generation high-performance motors that utilize amorphous laminated cores, in order to create killer content from Japan that can achieve carbon neutrality.
