Abstract: For the higher precession of step motor, with high speed and performance microprocessor C8051F005 as the kernel, combining with blending step motor driving chip L297/298, the driving control system of step motor of switchmode and constant current was designed. The experiment shows that the control system runs stably with the merit of little stepping angle unvaried torque and low power consumption and has the higher precision in the running of step motor.
Key words: blending step motor; C8051F005; fine driving; L297/298
