42mm Hollow Shaft Stepper Motor

1.8deg 2.8v 1.68A 0.49N.m Nema17 42mm hollow shaft stepper motor

     Stepper motors enable accurate positioning with ease. They are used in various types of equipment for accurate rotation angle and speed control using pulse signals. Stepper motors generate high torque with a compact body, and are ideal for quick acceleration and response. Stepper motors also hold their position at stop, due to their mechanical design. Stepper motor solutions consist of a driver (takes pulse signals in and converts them to motor motion) and a stepper motor.
