Stepping drive superior mechanical control drawing step motor running must have a electronic device driver, this device is the stepper motor drive, it will control system of the pulse signal amplifier to drive the stepper motor. Stepper motor speed is proportional to the pulse signal frequency, control stepper pulse signal frequency can be precise speed control of motor, and the number of control step pulse can accurate positioning on the motor. Stepper motor drive control system is mainly composed of the following three parts: the step controller, drive and stepper motor. Stepping controller by single chip microcomputer, drive will microcontroller output pulse amplification, to drive the stepper motor. General single chip microcomputer control stepping motor system block diagram as shown. Can't use dc or ac power frequency direct drive stepper motor, must use dedicated step electric circuit, or use the special circuit, composed of discrete components. According to the flow of the motor starting current driver circuit is divided into single polarity driving circuit and bipolar drive circuit. Single polarity driving circuit to ensure motor winding current to flow along a direction, and is suitable for the reactive stepper motor; By controlling the bipolar drive circuit, can make the motor winding current is/reverse flow, applicable to the permanent magnet and hybrid stepping motor. 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.
