【Abstract】 In this paper,based on the use of switching control,analysis of the current problems in stepper motor driver is made,a solation is given by making use of high and low voltage drive and improved freewheeling loop to enhance stepper motor output torque.Field experimental results show that the program makes the output current lower and the torque higher,and it’s a very good improvement of the stepper motor drive performance.更多还原
