The document "Design and Implementation of Stepper Motor Control System Based on 51 Single Chip Microcomputer.pdf" introduces the design and implementation of a stepper motor control system based on the STC89C52 single-chip microcontroller. The stepper motor is a type of electromechanical component that converts electrical pulse signals into angular or linear displacement. The control system consists of a stepper controller, power amplifier, and stepper motor. By using a single-chip microcontroller for control, software replaces the traditional stepper controller, resulting in a simpler circuit, lower cost, and increased reliability. The software programming allows for flexible generation of different types of excitation sequences to control various stepper motor operation modes. In this design, the STC89C52 single-chip microcontroller is used to control the stepper motor. The timing square wave generated by IO port output serves as the control signal for the stepper motor, which is driven by the ULN2003 chip. Additionally, four buttons are used to control the motor's state, and four LED display diodes are used to indicate the motor's speed. Overall, this design showcases the effectiveness of using a single-chip microcontroller for stepper motor control, providing a cost-effective and reliable solution for various applications. The combination of hardware control and software programming allows for versatile operation and precise control of stepper motors. Key words: STC89C52, stepper motor, ULN2003 driver.
