Project Profile

Reduction and control of power loss in electrical appliances through
ultra-high efficiency soft magnetic nano-crystalline materials.

Aim of "Tohoku Innovative Materials Technology Initiatives for Reconstruction(TIMT)"

MEXT and Reconstruction Agencies aim to establish a new research hub to strengthen the universities and nano-technology industries in Tohoku region by industry-academia-government collaboration. Tohoku University plays a central role in development of advanced materials and their manufacturing technologies.

The new research hub aims to contribute to the recovery from the Great East Japan Earthquake by fostering the world's leading technologies for development of cutting-edge materials for industries in Tohoku region.

The area of "Ultra-Low Core Loss Magnetic Materials Technology" is described in the next section.

"Ultra-Low Core Loss Magnetic Materials Technology" initiatives

It is anticipated that the consumption of electrical energy in the world can be reduced significantly by the application of superior soft magnetic materials in electrical transport and various electrical appliances. The energy loss ( in the magnetic cores) in transmission and electrical appliances such as motors, transformer and so on, accounts for 3.4 % of overall electricity consumption in the world. Magnetic iron-silicon steels (96% is used in motors and transformers) are mostly used for such applications, and they are already approached to saturation in terms of their magnetic performance.

In view of the growing demand for energy, and depletion of earth's natural resources, it is necessary to develop superior soft magnetic materials for magnetic cores. High Fe-content nano-crystalline soft magnetic materials recently developed at Tohoku University have great potential for further reducing the core loss. The new materials are made from self-organized nano-hetero-amorphous alloys.

Essential design guidelines, which integrate theories of magnetism and the structure of applications are required to further advance the field of nano-crystalline soft magnetic materials. Contribution will be made in this direction.

Moreover, the multi-faceted collaboration between government, industry and academia motivated by this center could lead to the blooming of industries in Tohoku region.

Address from the Head Investigator

Our project has started since June 2012 with a financial support from Ministry of Education, Culture, Sports, Science and Technology (MEXT). We have succeeded in developing NANOMET® with excellent magnetic properties and its fabrication process. Furthermore, we also have succeeded in fabricating wide-ribbon samples and making practical-proof by assembling a motor. From now, we are planning to start collaborating with companies for motors and transformers at the latter part of the project.

To achieve this collaboration, we have moved to a new office (MaSC). With solid supports from companies, we are achieving industrialization of the project. Finally, I would like to have your further support and understanding regarding this project.
