Laboratory Overview
Human and environment-friendly electric motor technologies
In my laboratory, we work on improvement of conventional motors’ performance, and development of novel motors with high efficiency. And the development of control method of their motors is also one of our research themes. It is said that more than 100 years has passed since the birth of the motor. However, the motor technology still supports people’s lives in modern society.
Laboratory Character We have developed the motors for electric cars (Hybrid EV, Pure-EV) and some linear motors, and have proposed various novel ideas, such as application of vernier configuration to a traction motor for EV and to a linear motor and proposal of an integrated configuration of a radial flux rotor and dual axial flux rotor. My students have made a presentation on the research results at international academic conferences.
