Masayuki Morimoto, Professor, PhD
Masayuki Morimoto was born in Tokyo, Japan. He received the B.S., M.S., and Ph.D. degrees all in electrical engineering from Keio University, Yokohama, Japan in 1975, 1977 and 1990, respectively.
From 1977 to 2005, He was with Mitsubishi Heavy Industries, Ltd., where he has been involved in research and development of power electronics and electric machinery.
From 1994 to 2004, he was also a Lecturer of the Department of Electrical and Computer Engineering at Nagoya Institute of Technology.
From April 2005, he has been a professor of the Department of Electrical and Electronic Engineering at Tokai University.
Dr. Morimoto is a member of the Institute of Electrical Engineers of Japan (IEEJ), Institute of electrical and Electronic Engineer(IEEE), and Institute of Electrical Installation ojf Japan (IEIEJ).

Morimoto Laboratory
Morimoto Laboratory has established in April 2005. "Electric Motor of the next generation" is a target of the laboratory. Motors has its history over hundred years, though, the motors starts their evolution recent years. "3R (Recycle, Re-use and Reduce) Motors" is the keyword of our research subject.

Research area

Motors and their control
Inductors for Power electronics
Batteries for Smart Grid
Electric and Hybrid Electric Vehicle
Wireless Transmission of Electricity
