Some basics of stepper motors:

   Stepper motor is a kind of electrical pulse into angular displacement of the actuator. In Layman's terms: When the stepper driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (and stepper angle) in a set direction. You can control the number of pulses from the upper control system to control the angular displacement, so as to achieve accurate positioning, and you can control the speed and acceleration of the motor by controlling the pulse frequency, in order to achieve the goal of speed. Based on these advantages, stepping motor can be used in automatic industry and can be located accurately.
