The article designs a new drive controller for micro-step motor, which modifies speed, rotation angle and coefficient of segmentation of the micro-step motor through host computer interface. In the program STM32F103TSU6 is used as the master controller and the drive device of micro-step motor is A4988. Man-machine interface is serial port PC interface. In the article, the principle of the drive device of micro-step motor, interface circuit as well as the design solution of the controller is detaileal analyzed. The production achieves the following functions： the control of micro-step motor＇s speed, any angle of positive inversion and coefficient of segmentation. The control of any angle of positive inversion is achieved by means of pulse number of micro-step motor. The level .of precision of positive inversion＇s angle is up to 0.1125 degree.
