Unipolar/Bipolar Stepper Motor - 57*41/56/76mm

Description:

This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). 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.

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
