One magnet no bearing Bedini motor

Retrod:

Nice job on your replication!  Very quiet too.  I didn't know we could use twisted pairs spools of wire for out Bedini's.  A lot easier to wind than the way I have been doing it.

Great work.

@Retrod.What a great idea using the twisted pair and the marble.I wonder how your coil design compares with a standard mag wire bifilar?From what i could see,pretty well.I think you have set the new record  for building a Bedini,10 minutes WOW!
I am going to test your coil design as you may have just made everything a lot simpler.Thanks for your innovative replication and i hope you continue to experiment with it.Nice work Dave.Regards jonny

Thanks Bill & Jonny. I posted a follow-up. The coil is simply 500ft 2/c #24 with a twist. I did not re-spool, it's as it was right off the shelf :-). A true 'lazy man's' replication, Lol!

Hey retrod Cool vid, took me a lot longer than ten min though
got mine working good last night  will post vid later, didn't need the relay/ac motor coil after all, i think pirate was right it just needed a good spin, the ac motor coil did help though, it seems to start easier and at a lower rotation speed. the relay/ac motor coil seems like its giving some back emf and slows down everything...

fun stuff...

I used  the sphere shaped snake egg with two steel bbs on the poles so i could get it going the right way (one of the poles kept turning down to the core when i spun it) the bbs at one point flew off the egg and that thing took off almost broke the plate I had it on

anybody ever heard of beyblades.... like to put a magnet in one of those....

might have to put a steel cage around them though......death by spinning top does not sound like a cool way to go....
