The Control System of Step Motor Based on AT89S52 |

| Abstract: | In this design, step motor is controller by AT89S52 single-chip which output three-way control signals： the direction of the signal, enable signal and PWM wave. It realizes data communications between PC and single-chip microcomputer by using RS232. Using TA8435H chip to achieve the step motor-driven, motor speed can be controlled by adjusting the PWM duty cycle. The performance of the system has a certain reference value to the design of movement control system of the precision workstations. |
