An electrical pulse signal into angular displacement of the actuator. Its main advantages are high positioning accuracy, no cumulative error; Characteristic of the open loop operation mechanism, compared with the closed loop control system reduces the system cost, improve the reliability, has been widely used in the field of CNC. However, stepper motor in the vibration and noise during low speed running, near the natural oscillation frequency of the stepper motor runtime resonate easily, and the output torque as the stepper motor speed rise and fall, these disadvantages limit the application range of the stepper motor. Stepper motor depends largely on the performance of the drive, improves the performance of the drive, can significantly improve the performance of step motor, thus developed high-performance stepper motor drive is an issue of common concern. Typically, stepping motor drive system consists of three parts: (1) control circuit. Used to generate pulses, and steering control motor speed. (2) driving circuit. The research content of this article, by as shown in figure 1 of pulse signal distribution and power drive circuit. According to the pulse and direction of the controller input signal, provide correct stepping motor's winding current order, as well as the motor need to high voltage, large current; At the same time provide all kinds of protective measures, such as over-current, overheating, etc. (3) the stepper motor. Control signal is amplified by the drive after driving a stepper motor, drive the load. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
