This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 3.2 V, allowing for a holding torque of 18.9 kg-cm (260 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.
Specifications:
  • Size: 56.4 mm square × 76 mm, not including the shaft (NEMA 23)
  • Weight: 1 kg (35 oz)
  • Shaft diameter: 1/4? (6.3 mm) “D”
  • Steps per revolution: 200
  • Current rating: 2.8 A per coil
  • Voltage rating: 3.2 V
  • Resistance: 1.13 Ohm per coil
  • Holding torque: 18.9 kg-cm (260 oz-in)
  • Inductance: 3.6 mH per coil
  • Lead length: 12 in
More specifications are available in the datasheet (49k pdf).
Dimensions:
The following diagram shows the stepper motor dimensions in mm. The output shaft has a 0.25? (6.3 mm) diameter. Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 mm.

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
