1.8deg 1.7A 4.2kg.cm 2.55v 42mm Nema17 stepper motor with pulley

Stepping motor is an actuator that converts electrical pulses into angular displacement. In layman's terms: When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (ie step angle) in the set direction. You can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, you can control the speed and acceleration of the motor rotation by controlling the pulse frequency to achieve the purpose of speed regulation.
