This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2 A at 4.5 V, allowing for a holding torque of 14 kg-cm (190 oz-in). The motor has six color-coded wires terminated with bare leads that allow it to be controlled by both unipolar and bipolar stepper motor drivers. When used with a unipolar stepper motor driver, all six leads are used. When used with a bipolar stepper motor driver, the center-tap yellow and white wires can be left disconnected (the red-blue pair gives access to one coil and the black-green pair gives access to the other coil). We recommend using it as a bipolar stepper motor.

Specifications:
  • Size: 56.4 mm square × 76 mm, not including the shaft (NEMA 23)
  • Weight: 1 kg (35 oz)
  • Shaft diameter: 1/4″ (6.35 mm) “D”
  • Steps per revolution: 200
  • Current rating: 2 A per coil
  • Voltage rating: 4.5 V
  • Resistance: 2.25 Ohm per coil
  • Holding torque: 14 kg-cm (190 oz-in)
  • Inductance: 3.6 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. This shaft works with our 1/4″ 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
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives
