This paper introduces the structure and the design scheme of hardware and software of three-phase AC asynchro-nous motor control system based on the dsPIC30F6010 chip using digital double closed-loop vector control strategy. The chip of dsPIC30F6010 is adopted for the CPU development board, photoelectric encoder and the three-phase AC asynchronous motor. A new vector control system for induction motor is developed through the improvement of a driving power and a level conversion board of integrated IPM for current sensor. The results show that the motor is characterized by fast starting, stable operation, wide speed range and high precision, which meets the requirements of speed control for three.phase AC asynchronous motor.
