    Just saw this,

    Interesting.

    For those not interested in investing the 7mins to watch the video, the builder used a series of magnets to create a magnetic clutch in a driveshaft.

    My take is that it would work, but I don't know that it would work well in our application. We're putting a lot more torque through the shaft than that little RC car had. We typically have a lot more room to work with, leaving more options for gearboxes and gear reduction, larger motors, etc. which would be better solutions.

    Still... very unique solution to his problem. He talked about using magnets as a shock absorber as well. That's a really cool idea, too!

    Thanks for sharing!

      Didn't watch it, but isn't Tom already doing this? He may already have worked it out, or destroyed a neighborhood with an artificial Magnetar.

        Still playing with magnets......I am open to anyone making it work and improve.
        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

          I have experimented with magnetic couplers. My design looked like a revolver spindle. Alternating positive and negative polarity around the spindle. I also made the coupler extra deep so I could stack magnets to get the proper hold with an 1/8" plex wall. Worked well with a clutching effect if running into weeds or fishing line. Never found a model to use it in though.

            Yeah, I beenere and dunnit, too, but this solution from the video was pretty unique as the magnets formed part of the driveshaft directly.
