Stepper Motor: Bipolar, 200 Steps/Rev, 28x32mm, 3.8V, 670mA

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 3.5 V, allowing for a holding torque of 600 g-cm (8.3 oz-in).

5mm Pololu universal aluminum mounting hub on a stepper motor with a 5mm output shaft.

Overview

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 3.5 V, allowing for a holding torque of 600 g-cm (8.3 oz-in). The motor has four color-coded wires terminated with bare leads. Our 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5mm-diameter output shaft.

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
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives
