Stepper Motor NEMA 23 with Wire (8.6V 1A/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 8.6 V, allowing for a holding torque of 14 kg-cm (190 oz-in).

This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 8.6 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.

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.

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 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
