In this talk, 25 years research results of EEPEL led by Prof. Seung-Ki Sul will be introduced. Especially, the motor drive for traction application such as electric vehicle, crane, elevator, excavator, and ship will be discussed. Some examples for real industry application will be introduced with its energy saving record. Also, the control principle and application of the sensorless drive of AC motor, especially Interior Permanent Magnet Motor, will be addressed. The merit and issues of the sensorless drive will be discussed briefly.
Seung-Ki Sul received the B.S., M.S., and Ph.D. degrees in electrical engineering from Seoul National University, Seoul, Korea, in 1980, 1983, and 1986, respectively.
