What's the stepper motor?
Stepper motor is a kind of motor that converts electric pulse signal into corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates by an angle or advances one step. The angular displacement or linear displacement of the output is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. Therefore, stepping motor is also called pulse motor. Based on the most basic principle of electromagnet, the stepping motor is a kind of electromagnet that can rotate freely. Its action principle is to generate electromagnetic torque by the change of air gap permeability.
