What is stepper motor

Stepper motor is a control motor that provide precise position and speed control.

Stepper motor can convert an electrical pulse signal into an angular and linear motion, no need for feedback device to sense position. Also, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation. The motor and drive constitutes a low cost control system that is simple to construct.
