This hybrid bipolar stepping motor has a 1.8deg; step angle (200steps/revolution). Each phase draws 500mA at 10V, allowing for a holding torque of 1kg-cm (14oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.

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
