Rare-earth PM Brushless DC Motor Servo System

The measure using simple hardware to realize self-adaptation control in electric servo-drive system is presented in this paper. The control idea is described and the complicated control method is realized by 80C196KC with the simple hardware circuit, the motor in this system is rare earth permanent magnet brushless DC motor driving by square wave, having HALL as position sensor without speed sensor. The result of experiment shows that the system is simple, reliable, high precision in orientation and track, quickly responds to speed, widely speed regulation, good stability of motor speed, small torque ripple in low speed.
