Overview

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 500 mA at 10 V, allowing for a holding torque of 1 kg-cm (14 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:

  • Printers
  • CNC machines
  • 3D printer/prototyping machines (e.g. RepRap)
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives
