摘要	To increase the measurement precision of dynamic detection for an optical encoder in the steady speed, a turntable drive system with a brushless DC motor was designed. The influence of the speed fluctuation of dynamic detection equipement on the angle errors of the encoder was analyzed. A model of winding torque composition with space-vector was set up to make the torque's value to be a constant. Finally, the PI controller was added to this system, and the drive circuit was designed with a DSP+CPLD. The experiment shows that the drive system of dynamic detection equipment for the encoder can mantian the output torque stable in all the speeds. The steady speed precision of the system is better, and the steady error is less than 1 ()/s. The stable drive system effectively reduces the effect of speed fluctuation on the detection error and satisfies the dynamic detection requirement of photoelectric encoders.
