Product Overview

Stepper motor is an actuator that converts electric pulse into angular displacement, and controls angular displacement by controlling the number of pulses, so as to achieve accurate positioning. Under various control signals such as digital and analog communication, stepper motor is widely used in various position and speed control applications
