This one has been on my project to do list for a while! Check out this video if you're interested in finding out how magnetic gears work and how my quest to building a magnetic gear transmission using my 3D printer turned out.

How do you use a motor in an environment which a typical motor just isn't designed for? Say submerged in sea water or in an ultra-high vacuum? Or when you need to completely physically separate an assembly, tool or pump from the motor driving it?

If you've come across this problem before, then magnetic gears may be the answer. This type of non contact transmission relies on teeth that mesh using magnetism and can be physically separated from another by a wall or even a hull.

In this video, I'll be designing, building and testing a magnetic gear transmission using 3D printing. I'll also show you some engineering tricks for how to get more power out of the magnetic transmission.
