This high-torque hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 2.5 V, allowing for a holding torque of 13 kg-cm (180 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 6.35mm universal mounting hub can be used to mount objects on the stepper motor’s 6.35mm-diameter output shaft.

Specifications:
  • Size: 56.4 mm square × 56 mm, not including the shaft (NEMA 23)
  • Weight: 0.7 kg (25 oz)
  • Shaft diameter: 1/4″ (6.35 mm) “D”
  • Steps per revolution: 200
  • Current rating: 2.8 A per coil
  • Voltage rating: 2.5 V
  • Resistance: 0.9 Ohm per coil
  • Holding torque: 13 kg-cm (180 oz-in)
  • Inductance: 2.5 mH per coil
  • Lead length: 30cm

Dimensions:

The following diagram shows the stepper motor dimensions in mm. The output D-shaft has a 0.25″ (6.35 mm) diameter with a section that is flattened by 0.5 mm (note: the diagram below incorrectly lists this flattened width as 6 mm when it is really 5.85 mm). This shaft works with our 1/4″ universal mounting hub.
