Unipolar to Bipolar: 28BYJ-48 Stepper Motor Upgrade with explanation

Follow
Paul Chase

This is the longwinded method to turn your Unipolar 28BYJ48 stepper motors from unipolar to bipolar by cutting out the center coil.

I'll post a shorter, tothepoint video later, but the idea here is to cover the why, not just the how.

The Datasheet for these motors is here:

This is a precursor to using a cheap pancake motor to control your 3D printer or other precision device with improved and even silent stepping depending on your driver.

Thanks!
