Due to an expansion of electrical motor drive system application for transportation means such as a car, a ship, and an airplane, its high efficient and downsizing technology required more and more. Nowadays, when studies of power semiconductor material as GaN and SiC are going ahead, and 80% of electrical energy is expected to be used through power electronics technology in 2030 such as a realization of distributed power supply system from mW level to GW level, it is said to be that the bottleneck technology has become magnetic material in a viewpoint of downsizing, cost, and efficiency. So a new magnetic material for high power and high frequency is required strongly. One of the solutions for the requirement is thought to be a mutual consideration of magnetic material and power semiconductor. Then, future trend of electrical motor is considered to be motor physics as microscopic direction as well as motor integration as macroscopic direction.
