Stepper motor is widely used, is one of the most critical products of mechatronics; With the development of science and technology, the use of stepper motor drivers is increasingly important.
    The biggest feature of the stepper motor that differs from other control motors is that the stepper driver is controlled by the input pulse signal, that is, the total rotation Angle of the motor is determined by the number of input pulses, and the speed of the motor is determined by the pulse signal frequency. If you send a control pulse to the stepper motor, it will turn one step, and send another pulse, it will turn another step. The shorter the interval between the two pulses, the faster the stepper motor will turn. Adjusting the pulse frequency sent by the single chip microcomputer can speed regulate the stepper motor. It can make the motor run smoothly at low speed, almost no vibration and noise, and the torque of the stepper driver is much higher than that of the two-phase and five-phase hybrid stepper motor at high speed. Positioning accuracy up to 60,000 steps/revolution. And we confirm that the amplification of the control signal is the core work of the driver.
    Stepper motor must have a driver and controller to work properly. The function of the stepper driver is to distribute the control pulse in a ring and amplify the power, so that the winding of the stepper motor is electrified in a certain sequence and the rotation of the stepper motor is controlled.
