| Abstract: | The step motor was used widely in the digital control field.There is numerous kind of Stepper Motor Drivers in the market,but still can not meet the requirements of precision instruments perfectly in some special occasion.The principle of constant current division driving and constant torque control strategy was presented in this paper.A novel stepper motor control system was introduced in this paper,which takes a AT89C52 as the core controller,combined with double 8 bit D/A converter,stepper motor controll... |
