One magnet no bearing Bedini motor

[Mark]

Good idea with the slave coil Jonny. Does anyone have a tach to check the speed on one of these snake rocket spinners? Have you tried to put your pickup coils in series to boost the charge rate?

@Mark:
Actually a parallel setup seems to charge the cap faster than a serial setup surprisingly.
There must be very little current coming from the coils in fact.

Running it on super caps

I got this running stable enough to go to the next step. I have it running on super capacitors. I found that a capacitor will charge up better on the back end than the NiMh batteries I'm using so I decided to just put super caps front and back and see what happened. It worked. I don't think that my SEC is going to run this wirelessly but it can charge up a capacitor wirelessly. When that capacitor gets enough energy in it, then it could be used to run this Bedini.
I also found out that a Joule Thief will run very nicely off the air core pickup coil-- even from several inches away from the magnet.
Here is a video of the the latest.

Lidmotor that's sweet. Have you tried to make it self run yet?

That really surprises me. Whould it make any difference if all the coils were in series and then had just one bridge rectifier?

[Vortex]

If a Self-starting (self spinning) with enough power could be obtained,
then it would be easy to use two magnets, one above and one below the bifilar coil.
The above and below magnets would spin in sync with each other.
A short stack of washers, a small ball bearing in the hole and two or four magnets
on the outer edge of the washers might self start easier.
Height of magnet over the coil is probably an issue, too close to the coil and it might not spin.
Height might prevent a sphere magnet from working.
See video to see magnet configuration.

Hi Vortex

Just watched your video and I'm not sure whats going on. I see all the magnets spinning on the bowls but whats powering them, sound? I dont see any coils.

@Lidmotor.Thats Blown me away. I did not realise supercaps behave like that and don't just dump there charge.What happens when you swap caps from charge to run and how does the charge rate compare with the discharge rate of the two caps?regards jonnydavro

SEC linked to the Bedini---wirelessly

It's late and I just had time to take a quick video before the wife gets home and all fun stops.
I got the SEC to link wirelessly by using a Joule Thief and super capacitors. It's pretty cool. It doesn't quite run it but it is close.

@Lidmotor.You have done so much in a short time to move this project along.Thanks
@ALL.Today i tested Comwarrior69's idea of using a darlington transistor instead of an npn and the results were quite interesting.I could get the magnet to maintain rotation on 3mA at 2.9V which is the lowest current draw i have had on a bedini to date.I also found that i could not get as high rpms as i can with an npn so i have asked Comwarrior if he has any suggestions on that.
The transistor i used for this test was a TIP 120.
Here is a vid of the test.Regards jonnydavro.

Idea

@Jonnydavro: This experiment doesnt stop to amaze me and your flood of cool ideas to improve this

I just had an idea that you might wanna try out.
Since a darlington pair is nothing else than this connection of transistors :



i see the possibility to insert another relay coil in the base feed of the 2nd transistor in the case that you just use two 3055s to realize the darlington pair.

The amp-draw might stay low but maybe it will speed the rotation up just like in the case of using the relay coil with just one transistor.
Just an idea.

Keep up the good work

The Darlington Pair

I learned about this when I was working on the "Aromaz" project. We were pairing a 2n2222 with 2n3055s. Initially Aromaz's design had the base on the 2n2222 completely open and it was paired with a bunch of 2n3055s. We were running an ignition coil that was driving FLs. I kept burning out 2n3055s and started reducing the circuit down as I ran out of parts until it was down to just the two transistors. I actually made one circuit that was just two 2n2222s paired. I "tickled" the base of first transistor with a loop of wire around the ignition coil. It ran on low voltage and drove a CFL at dim light. I called it my " Table Candle". I ran it for days on a pack of AAs.
This Bedini design should run nicely on this Darlington pair. Havn't tried it yet but will. Today I took the energy coming off the third winding of my coil, ran it through a bridge rectifier, and sent it straight back to the source battery (0ne AA). I expected it to just kill things but it didn't.

Jonny ----Your motor just continues to amaze me!!!

snake magnet..

Question,

Could one not make one "Bigger" would like to see a large neo like this spinning ... Was wondering if you could custom make one of these magenets..

[jonnydavro]

Hi. Comwarrior has been in touch and suggested i try using 2 2SC4106 transistors so i have ordered some and will see if that speeds things up.
I would like to try 2 mpsao6 as Lid got some strange scopeshots using one so if we use two?I can't source them in the uk so may be Lid can check that out.
@Xenomorph.That suggestion could be genious.Thats what i like about this forum i mean who would of thought of trying that?.Nice one
@Lidmotor.Sounds like you have got your motor running real nice.One AA battery,Sweet. and feeding back to source,WOW.I think i am going to wind my coils trifilar in the future as your third winding does not seem to effect current draw to much as you have it running on 10mA or less.I think there may be plenty more suprises yet to be discovered and you may have made one today.

I would think so, theremart.
Standing the snake magnet on end, the north/south poles are in the middle and point to the left/right if I understand it correctly.
I don't see why one or two, etc, neo magnet(s) could not be placed into a plastic easter egg, ending up with a similar shape and magnetic field?
I am still thinking distance is a factor. The magnet being too close to he coil would not result in spinning.
If distance is a factor, a sphere would have to be higher up off the coil than the snake egg to spin..

Just ideas and
Randy
