1476-POLOLU Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57×41mm, 5.7V, 1 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 1 A at 5.7 V, allowing for a holding torque of 4 kg-cm (55 oz-in).
This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 5.7 V, allowing for a holding torque of 4 kg-cm (55 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).

Dimensions
The following diagram shows the stepper motor dimensions in mm. The output shaft has a 0.25″ (6.35 mm) diameter. Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 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
