This NEMA 14-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 2.7 V, allowing for a holding torque of 1.4 kg-cm (20 oz-in).
This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 2.7 V, allowing for a holding torque of 1.4 kg-cm (20 oz-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:
- CNC machines
- 3D printer/prototyping machines (e.g. RepRap)
- Laser cutters
- Pick and place machines
- Linear actuators
- Hard drives
