Bedini / Davro no bearing motor re-visited with spiral wound coil

I made this to experiment with a compact spiral wound coil. The design is very simple using an empty tape reel and two rolls of copper foil tape. Makes for an easily controlled build, also easy to stack. Have fun and be safe.

The magnet's skiding along it's side. You need to stand the spiral coil on end to get the sphere to spin on it's axis.

Yes, it does help. I just posted a video with the coil vertical.

Thanks

Handsome coil, that ribbon should be able to handle quite high power levels I think!

Try a cylinder neorotor with a shaft and bearings, and crank it up to 12 volts then 20 volts and you could generate quite a bit of torque, power, back-spikes, etc. Thanks

The coil is capable of spinning the magnet at great speeds. A stable magnet is a must to be safe.

Thanks
