Making Life Easier with a DC Motor Hollow Shaft Setup
If you've ever tried to run wires through a rotating joint without them getting tangled into a giant knot, you probably realized pretty quickly how much a dc motor hollow shaft can save your sanity. It's one of those engineering solutions that seems so simple once you see it, but before you have one, you're stuck trying to figure out how to bypass the laws of physics with slip rings or complex mechanical linkages. ...
