by Pololu

This NEMA 11-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution).

Each phase draws 670 mA at 3.8 V, allowing for a holding torque of 600 g-cm (8.3 oz-in).

The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.

Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft.

Dimensions

The following diagram shows the stepper motor dimensions in mm. The dimension labeled “Length” is 32 mm. The output D-shaft has a length of 20 mm and a 5 mm diameter with a section that is flattened by 0.5 mm. This shaft works with our 5 mm universal mounting hub.

Stepper Motor Applications

Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found:

Printers
CNC machines
3D printer/prototyping machines (e.g. RepRap)
Laser cutters
Pick and place machines
Linear actuators
Hard drives
