Outline

Pioneering fusion technologies(from materials to applications) for electromagnetic equipment, with focus placed on research of electromagnetic fields

We conduct research on electromagnetic energy applications such as linear motor cars and electromagnetic processing, and integrated research on electromagnetic fields such as electromagnetic actuators which make use of material roperties in order to establish technologies for reducing environmental impact.
We aim to develop a broad scope of research activities from basic theoretical studies, prototyping/evaluation, to commercialization in collaboration with companies.

Research Themes

Research on power electronics for motor-driven systems, such as electric vehicles
Research on applications of electromagnetic energy systems for linear motor cars and material processing
Research on the interaction between electromagnetic energy and substances
Research on technologies for reducing environmental impacts by employing electromagnetic energy systems which make use of material properties
