What is a stepper motor stepper motor is a kind of special accurate control for position and speed of the motor. The biggest characteristic of stepping motor is a "digital", for each controller sending a pulse signal, step motor driven by the drive running a fixed Angle (referred to as "step"), as shown in the figure below. Such as received a bunch of pulse stepper motor will run continuously a appropriate distance. But by controlling the pulse frequency at the same time, directly to control the motor speed. Due to the working principle of the stepping motor to learn and easy to use, low cost (relative to the servo), motor and drive is not easy to damage, is very suitable for microcomputer and single chip microcomputer control, thus in control equipment from all walks of life in recent years got more and more widely used. Stepper motor ?
