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.

Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft.

Specifications

  • Size: 35 mm square × 28 mm, not including the shaft (NEMA 14)
  • Weight: 140 g (5 oz)
  • Shaft diameter: 5 mm “D”
  • Steps per revolution: 200
  • Current rating: 500 mA per coil
  • Voltage rating: 10 V
  • Resistance: 20 Ω per coil
  • Holding torque: 1 kg-cm (14 oz-in)
  • Inductance: 13.5 mH per coil

More specifications are available in the datasheet (185k pdf).

Dimensions

The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 28 mm. The output D-shaft has a length of 21 mm and a 5 mm diameter with a section that is flattened by 0.5 mm. This shaft works with our 5 mm universal mounting hub.

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
