Hybrid Mini Nema8 High Speed Stepper Motor 20mm*20mm*30mm High Torque 180g.cm 2.5oz.in 0.6A
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.
