Hitachi Develops High-efficiency Motor Without Using Neodymium

By Shinya Saeki – Hitachi Ltd and Hitachi Industrial Equipment Systems Co Ltd co-developed a permanent magnet synchronous motor with an efficiency of 93% without using a neodymium (Nd-Fe-B) magnet, which contains a rare-earth material.

With the new technologies, it is possible to realize an industrial motor whose performance is equivalent to that of a neodymium magnet-based motor at...
