Tips: What is a stepper motor driver?

Stepper motor driver is mainly composed of ring distributor, push stage, protection circuit and sensor. The function of the circular distributor is to generate the switching waveform signal processing of the motor in different states according to the requirements of the input signal. The driving stage is to amplify the voltage and current of the switching signal to enhance the main switching circuit. The protection circuit is responsible for generating a shutdown signal to shut off the main circuit when the winding current is too large to protect the motor driver and motor windings. The sensor is responsible for real-time monitoring of the position and angle of the motor, and the generating device for returning the signal the role of.
