One magnet no bearing Bedini motor

[jonnydavro]

Hi.Today i did a test using an aircore bifilar coil and a 6mm Neo sphere.The motor ran very economicaly on 1.4v@1.75mA and 2mA when lighting the led.I used a pickup coil to light an LED and i was also recovering the bemf from the relay coil and power winding.This was just a quick test to see if you could get such a small magnet to work so it's not pretty and the sphere is hard to see but it is in there spinning away and there are lots of places to make further savings starting with the elimination of the cardboard end stop which the little ball is rubbing against.I made a vid as i was suprised it drew so little current and here is a closeup pic showing the coil and cardboard endstop retaining the sphere.Regards jonny
@Retrod.Real nice job with the twin rotors.Looks like you are having fun.
@Pyrodini.Good job getting your motor going.Feels much better when you solve the problem yourself don't you think.One word of caution though,if you are using the sphere's then you shouldn't need to add small ball bearings,they will spin by themselves and you could end up hurting someone if they part company.Happy experimenting regards jonny

The ball bearings are just to keep the orientation of the magnet with the poles east to west instead of up and down, the sphere mag has a tendency to rotate the poles to line up with the core, the bbs fly off at a low speed after the coil picks up the snake egg. the egg was what almost broke the plate, it was spinning so fast it really starts to chatter, I think I will try some oil like Retrods.

It does feel good to have built it and to have a better understanding of the circuit, thanks again for your insight. also its fun to amaze friends......

Does this have a patent or something associated with it? I would hate to see somebody or some corp. reading these threads grab it up, heard an ad the other day on the radio for a "bedini charger", wonder if he gets any of that....
anyways a eternal spinning top would make a good toy and whoever made it first should get some credit ( jonnydavro?). unless this is considered free domain and anybody can use it for whatever?
Personally I don't intend to sell em or anything, just see the possibility.....

First an observation. I noticed if I have a stack (5 or more) of the 'button' style neos anywhere near the operating rotor the magnet stack will produce the same tone as listening with induction microphone & amplifier, only not nearly as loud. If you hold any neo magnet nearby you will feel the intense vibration as well.
Here is my first attempt at loading the circuit with an external coil. I used what was at hand, a very old color TV degaussing coil. Since the video was made I have added additional LED's and can light seven easily.

finally ....here's a vid of my bedini motor, you can hear the kickback from the ac coil, its a lot quieter with the ac coil bypassed but doesn't start as easy.....

I'll make one of the snake eggs later too....

Hi.I think i may have made a bit of a breakthrough with this.I have been experimenting with Neo sphere's and i wondered if i could combine the very powerful cylinder magnet with the sphere's and you can.This is what i did.
I used the cylinder magnet as the main rotor and i placed small 6mm N42 sphere neo's into seperate plastic containers with lids.I found i could get a satalite rotor to spin at a distance of 12" from the main rotor so that give's a 24" spin zone around the main rotor.I also found that i could stack them.I think you could spin as many magnets as you can get close to the main rotor.I only had 10 of the 6mm sphere's but after todays test,i have ordered another 40.I can also recover energy from the satalites witha pickup coil and i found that if you place a pickup coil between two pairs,they will share it so thats another bonus.
Here are some pics and a video.regards jonny.
