Magnetic Materials
Research Dept.

We, the Magnetic Materials Research Dept. of Advanced Components & Materials Research Laboratory, research and develop higher performance permanent magnets to materialize smaller, higher power, fewer energy consumption motors. We were established in 2006, inheriting the technical know-how that invented the highest energy rare earth permanent magnet, NEOMAX^®, in 1982. We moved to Kumagaya area in 2018, in order to have a closer collaboration with our production factory.
We will fulfill our expected rolls as the pioneer of the permanent magnet development, utilizing our powder metallurgy material technology, magnetic circuit design and analyze technology.

Permanent magnets are utilized within a broad range of applications like automobile, industrial infrastructure, electronics and so on, as the critical component of the motors that determine motor's performance.
Because of the increased environmental concern, tighter CO₂ emission and fuel efficiency restriction, xEV^* production volume is expected to grow rapidly all over the world. We shall increase our production capacity to fulfill the vigorous demand, and more than that, we shall develop the way to reduce the resource consumption.
Nd-Fe-B magnets used in automotive application, like xEV, contain heavy rare earth elements (HREs) such as Dy(dysprosium) or Tb(terbium) in order to achieve required high temperature resistance. However, HREs are literally extremely rare resources, with very limited production. We, the Magnetic Materials Research Laboratory, are focusing our R&D resource onto less HREs or HREs free magnets, in order to resolve the problem. Also, we conduct R&D for higher performance ferrite magnet, using our experience, being the pioneer in the new ferrite material development. We are also collaborating with Global Research & Innovation Technology center (GRIT), the corporate research laboratory, to develop the next generation permanent magnet.
