Magnetic Gearbox Design Improvements Are Toothless But Still Cool

Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting h…

3D Printed Strain-Wave Gearbox Turns Up The Torque

3D printers are good for a lot of things, but making parts for power transmission doesn’t seem to be one of them. Oh sure, some light-duty gears and timing belt sprockets will work just fine …

Wireless Power: Here? Now?

Outside of very small applications, Nikola Tesla’s ideas about transmitting serious power without wires have not been very practical. Sure, we can draw microwatts from radio signals in the ai…

Adding Wire Races Improves 3D-Printed Bearings

Like a lot of power transmission components, bearings have become far easier to source than they once were. It used to be hard to find exactly what you need, but now quality bearings are just a few…
