电磁跷跷板Abstract
Stepper motor controlled by a pulse signal, and a pulse signal can be converted to the corresponding angular displacement or linear displacement of the digital motor. As the stepper motor has a step error does not accumulate, reliable, simple structure, small inertia, low cost, and therefore, are widely used in computer peripheral circuits, automatic control devices and other digital control devices, such as printers, watches and clocks , digital to analog conversion equipment, and other devices. With the rapid development of science and technology, the corresponding control system also produced many types of stepper motor figure can be seen in many areas. Which uses microcontroller as the control of the control system, because of its simple circuit, low cost, high reliability, etc., to meet the needs of many fields, we get a lot of use. Therefore, based on single-chip stepper motor control system has important practical significance.The design study is 51 single-chip stepper motor control system. As a control signal, the signal through the chip
ULN2003 stepper motor drive to work through the microcontroller I / O port output timing square wave. Depending on the need, through the key circuit to control the start and stop, reversing and ramp functions such as stepper motors, stepper motors in real-time display and digital working condition. In this paper, the circuit diagram of each module, and with the ISIS Proteus software for each function control system simulation, and the simulation results are given corresponding image.
