6-lead, unipolar/bipolar stepper motor wires are terminated with bare leads.

6-lead, unipolar/bipolar stepper motor wiring diagram.

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). Pololu recommend using it as a bipolar stepper motor and controlling it with an appropriately powerful bipolar stepper motor driver, such as Pololu's High-Power Stepper Motor Driver 36v4, or Pololu's Tic 36v4 High-Power Stepper Motor Controller. In particular, the Tic makes control easy because it supports six different interfaces (USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder) and is configurable over USB with Pololu's free configuration utility.

NEMA 23 stepper motor (item #1475) mounted with a steel L-bracket for NEMA 23 stepper motors.

Pololu's 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 Pololu carry a NEMA 23 steel bracket for securely mounting this stepper motor to a flat surface.

More specifications are available in the datasheet (39k 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. This shaft works with Pololu's 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
