This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 4.5 V, allowing for a holding torque of 950 g-cm (13 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 5mm universal mounting hub can be used to mount objects on the stepper motor?s 5mm-diameter output shaft.

Specifications:

Size: 28 mm square × 45 mm, not including the shaft (NEMA 11)

Holding torque: 950 g-cm (13 oz-in)
Inductance: 4.9 mH per coil
Lead length: 30 cm (12?)
Output shaft supported by two ball bearings

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
Laser cutters
Pick and place machines
Linear actuators
Hard drives
