@WilbyInebriated:

The 2nd magnet would have to be brought in at the exact speed and phase of the first magnet onto the 2nd core-end
or it would interfere the first magnet's push from the transistor.
I guess that is close to impossible.
Even if you would manage somehow to do that, the amp-draw would simply double, no real benefit in using two magnets hypothetically.
To understand that, i recommend watching this MIT professor explain how this magnet motor works:
http://www.youtube.com/watch?v=FGaSeSP0tCM&feature=player_embedded

The magnet and the transistor work together in sync.
hi, thanks for the reply. magnet two wouldn't be brought in. it would already be in place.

Then i dont understand your set-up.
What would start the 2nd magnet then ?
Do you expect the coil field to start up the 2nd magnet?
That might work or not, i am not sure if the 2nd magnet
would really start to move without kicking it manually a bit.
Would be worth trying it out.

yup, that's pretty much what i was thinking. i am not sure if the second magnet will start either. i'll probably try it out when i get some time, just to see. feel free to beat me to it.  ;D

Hi all.Some great things going on here with the  pick up coil tests.I have been busy also, exploring alternative ways off powering the motor and can run it quite happily of a solar garden led light which will charge two 2.7v 20f supercaps in 10 minutes.I can also charge a supercap via a dynamo torch i have modified in a about one minute.The motor will run for hours on this charge.I have made a vid so you can see what i mean.

@wilby.I have been experimenting with a slave coil, i have a vid posted of that experiment but i also set it up next to the master coil and put a lid on it and span a magnet up on the master and moved the top over to the slave and then span another magnet up on the master to supply the trigger and it showed signs of life but i think the magnets would have to be identical as they would have to syncronise and i have built quite a few multi rotored Bedini's and i know if they  are not the same,they won't sync so you may have to make custom rotors.Regards jonnydavro

thanks jonny, it was your multi rotor setups that made me think of it.
maybe spherical magnets would be easier to match?

@wilby.For it to work,i think both magnets would have to remain in a fixed positions on the lids or they would de-sync.This is a problem with the snake egg as it likes to wander and with the more stable X spinner you would have to find two with the same rotational axis so that would not be easy.Sphere's are certainly worth a try.I think if you made spinning tops you could run them in sockets on the lids so that may keep them fixed in position and you could make two the same.EL-tigre has a  spinning top version at the one magnet bedini thread on energetic forum which might give you some idea'sHope this helps but i like your thinking with the u shaped core/coil.
There is another pole there to exploit so what else can we do with it?

New Rotor Test
« Reply #96 on: May 14, 2009, 03:30:19 PM »
Hi.I have some N42 20mm x 20mm with 6mm hole  Diametricly magnetised cylinder magnets which i have got for another motor i am working on and i wondered if i could adapt them to work on the one mag bedini and i have and it spins fast.Is what i did was i placed an 8mm ball bearing in the hole as a pivot and it is very easy to start and it triggers the transistor from 8 inches above the coil but it gets even better.I can run multiple rotors at the same time and current draw does not seem to be affected.In the video i am running a snake egg and the N42 cylinder at the same time.I have another N42 and will try and get the 2 N42's going but i thought i would let you know what i have for now.Here are some pics and a vid.Regards Jonnydavro

Hi all

A new video of the ball magnet reaching high speeds

http://www.youtube.com/watch?v=HQzpdcQf-Wk&feature=channel_page

Translation of alfacentauro1111 info from video

"Motor magnetico funcionando sin rotor , doble bobina una de señal de trigger y otra de pulso para impulsar el iman bola en su polo creando asi una aceleración, el circuito que se utilizo es el conocido bedini"

"Motor function without magnetic rotor, a double coil trigger signal and a pulse to drive the ball into his magnet pole creating an acceleration, the circuit used is known Bedini"

Regards,
Paul

Great job Jonnydavro,

I haven't had time to try to get multiple spinners yet. I did try the eggs and can get really close.

I did try a round mag with a top type setup but could not get it to spin up to speed. Will give it a go again soon.

Jonny:

Great new video you posted today!!!  I don't understand how those are running that far off to the side of the coil but, it is really cool.  It looks like you have enough space to run 2 more set-ups for a total of 4 rotors from one coil!!!!  This just keeps getting better and better!  Fantastic work!

@Brownsville.Thanks.Stick at it and you will get them going.
@Pirate.Thanks Bill.The setup i am using here is an air core power coil and these magnets are so strong that they trigger the transistor from miles away.This also means that they can be effected by the coils magnetic field from a distance so this is why i can run them like that.Regarding adding another two.you read my mind. ;)DRegards jonny

Hi.I subscibe to smw1998a on utube and thought you may be interested in his work.He makes some great bedini motors amongst other things and he has replicated the snake egg Bedini and put it on a scope.In his first vid he clocks it at 24000rpm and in his second 33600rpm.Here are links to his vids.Regards jonny

Hi.Some people who want to try the cylinder rotor are finding it hard to find diametricaly magnetised N42 cylinder mags with a hole so this is where i get mine from and i think they ship international.

Thanks for posting that link.  How did you know I was going to ask you that?
