Originally designed for control of HVAC vanes and similar low-demand equipment, these stepper-motor gearboxes have lots of hacking potential. This is the higher-torque / lower speed 64:1 version.


Description [Hide]

We had some of these drop on our desk a while back with a "You gotta find more of these!" message taped to it. What it turned out to be is a pretty cool, inexpensive geared stepper motor, ideal for a bunch of low-torque applications.

This 28BYJ-48 is a 5V unipolar geared stepper motor, manufacted by the boatload for the HVAC control industry, where you'll find these little units as actuators for airflow control in ducts and vanes. It features a 5mm "Double-D" shaft, mounting lugs, and nice 5-conductor 0.1" pitch connector. The gearing isn't the beefiest or most precise we've ever seen, but it's adequate for reasonable loads.

This version is the 16:1 reduction version (16.032:1, actually), so it's faster and less torquey than it's 64:1 brother.

Being a stepper motor, you'll need a motor driver circuit. There's many ways to drive a stepper, but this ULN2003 driver board is specifically designed to drive these 5V stepper gearmotors.

Specifications:

  • 64:1 (63.68395:1) gearing
  • Solarbotics Tested
  • Torque @5V:
    • FULL Step mode: 821gmf*cm (11.4in*oz) @ 200mA draw
    • HALF Step mode: 598gmf*cm (8.3in*oz) @ 256mA draw
  • 2038 steps per revolution
  • 4-phase unipolar stepper wiring through 23cm (9") long cable to 5-pin connector (0.1" pitch)
  • 5V nominal voltage
  • ~35 ohms coil resistance
  • Basic dimension:
    • 28mm diameter
    • 20mm tall (excluding shaft)
    • 5mm dia. "double-D" shaft, 9mm long
  • 37g

Thanks to Graham Wideman for his additional in-depth analysis on these gearmotors.

35STH40 NEMA-14 Bipolar 40mm Stepper - Dual Shaft

This motor is about half as small as our NEMA-17 Stepper and as a result only needs about half the power. Compared to the other NEMA-14 stepper we carry, it's a little longer but has the option to mount an encoder to the rear shaft!
