Study on Driving System for Electric Vehicle

In order to achieve a essential requirement for the driving system of electric vehicles, that is, starting pick-up ability, a wound-type induction motor with double-rotor structure is proposed. Slip Power Recovery system is adopted to improve the efficiency in the low speed range and to control speed of this system. Theoretical analysis and experimental results from 300[W] prototype motor is presented to verify the improvement of pick-up ability and high-efficiency driving characteristics through the wide speed range, especially under the low speed range.
