1473-POLOLU Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57×56mm, 3.6V, 2 A/Phase

This NEMA 23-size hybrid stepping motor can be used as a unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps/revolution). Each phase draws 2 A at 3.6 V, allowing for a holding torque of 9 kg-cm (125 oz-in).

Overview

This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2 A at 3.6 V, allowing for a holding torque of 9 kg-cm (125 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.

Our 1/4″ universal mounting hub and 1/4″ scooter wheel adapter can be used to mount objects on the stepper motor’s 1/4″-diameter output shaft, and we carry a NEMA 23 steel bracket for securely mounting this stepper motor to a flat surface (the picture above shows this bracket being used with a taller NEMA 23 stepper motor).

Specifications

  • Size: 56.4 mm square × 56 mm, not including the shaft (NEMA 23)
  • Weight: 0.7 kg (25 oz)
  • Shaft diameter: 6.35 mm (0.25″) “D”
  • Steps per revolution: 200
  • Current rating: 2 A per coil
  • Voltage rating: 3.6 V
  • Resistance: 1.8 Ω per coil
  • Holding torque: 9 kg-cm (125 oz-in)
  • Inductance: 2.5 mH per coil
  • Lead length: 30 cm (12″)
  • Output shaft supported by two ball bearings

More specifications are available in the datasheet (49k pdf).

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 and 1/4″ scooter wheel adapter.

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
