28BYJ-48 Stepper Motor

Description

This is a CAD model of popular 28BYJ-48 Unipolar Stepper Motor. The gears are not modelled as correct involute profile, though all other parts are as accurate as I can practically measure. These motors can be converted to be used as bipolar stepper motors: <iframe width="560" height="315" src="https://www.youtube.com/embed/lLF9_rc9G3I?si=OcvXs6Iis3fjL_os" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
