Development of driving motor system for small electric vehicle

Driving motor system using resolver input and sinusoidal wave driving, which is used to drive the small electric vehicle, is developed. Driving motor system is consisted with permanent magnet type motor and resolver input and sinusoidal wave driving type motor driver. In this work, driving motor is designed using the electromagnetic analysis with finite element method, and motor driver is designed to generate sinusoidal waveform using the digital signal processor (DSP), and driving program is designed. From the performance test, the developed driving motor system has the performances such as rated output of 5kW, rated torque of 13.0Nm, rated velocity of 3000rpm, respectively.
