One magnet no bearing Bedini motor
« on: March 28, 2009, 09:21:55 PM »
Hi.I saw a video on utube recently off a Bedini motor that only used 1 magnet and found it interesting so here is my version.
It is a standard Bedini circuit with a bifilar coil and core.The coil sits upright and i place a platic lid from a coffee jar on top.For a rotor i use one off those crazy magnets which are usually sold in pairs and make a loud noise when they attract each other.I have had the motor running today on 3 depleated 1,5v batteries which gave me 4.2v and once its going you can knock it down to 2 batteries.The combined voltage off my 2 batteries was 2.6v and it will start on 2 good ones.It will use 30mA on 3 batteries and and 17mA on 2.
This motor spins really fast at this low voltage and i have also run it off my joule thief and small solar panel and i even tried it on a 12v car battery and it sounded like a jet engine so i am going to stay with low voltage for the moment.
It will charge batteries but i have no imformation for you on this yet as i have been playing with it all day and having fun,it would make a really neat toy. ;D
Here are some pictures off it and a video. Regards jonnydavro.

Never seen a dancing Bedini, very cool thinking ;D

Hi, just an update.I have added a couple off pickup coils to recover some energy.I have some more coils so i will try adding them aswell.I just wanted to see if the spinning magnet would maintain it steady position in the presence off the pickup coils and it does.One other thing. Some thing i found interesting is i have quite a few off these crazy magnets and most off them have a slightly angular rotation around the vertical but i have one which spins completly upright.Out off the two,the angular rotation ones seem better for use with the pickup coils also this motor will run on a 1.5v battery at 6mA.This seems very low consumption.Does any one know off a really small solar cell that would power this?I have a 2.4 watt but that is overkill,there must be tiny ones which i could use hopefully. Anyway here is a vid off my motor with pickup's.Regards jonnydavro. ;D

Hi jonnydavro,

It reminds me of Tesla's Columbus egg more than Bedini's motor. Nicely done, thanks for sharing.

Take care,

Michel

Hi.Here is a replication from Xenomorph.
http://www.youtube.com/watch?v=s18_kZBIOp0
I took some pics which show the crazy magnets pole orientation and a test i was doing with 8 pickup core's and a concave nonmagnetic lid.
@michelinho.Hi. ;DThe similarities between this and tesla's egg are only visual.The tesla egg is using 4 coils and lots off ac current.This uses 1 coil and dc.

Great find Johnny!

Have you tried the same set up over your joule thief coil yet?

Really interested to find out the generated current and voltage coming from the pickup coils.

How many winds are in your Bidini Coil?

Would a coil like Lidmotors coil that went into self ossilation work as well?

I really have enjoyed all of your videos and am looking forward to more.

I happen to have an extra 2" ferrite torroid core and was wondering if using that as the core for a Bidini type wound coil would produce the same effect?

Great work.

I have some of those magnets, can we have some circuit and coil details please?

I`d build one just because it would look cool...

Thanks.

@Brownsville.Hi and thanks.The pickup coils seem to be working quite well.In the small tests i have done so far each pickup coil should pickup at least 1v and i am planning on using 8.If i use one individualy it can pickup 3v,more if the magnet bumps into it.I am just deciding which type off magnet will produce the most consistent output..I don't know if you are aware i have one magnet which spins vertically like a balerina and another which spins at a slight angle to the verticle.The verticle one ,moves about a bit and the later one is very stable.I will have to do some more tests later in the week to see which way i am going to go.
My coil is 1:1.It is made from two 250gram spools of 26swg enamel wire.There is 170 meters off wire per 250grams and is wound bifilar.I think lidmotors coil would be fine for this.
Regarding your ferrite.I don't know is the answer.I would try it and see.
Thanks for your interest regards jonnydavro
 @Lakes.This motor is very easy to build.If you build a standard bedini circuit  and coil and add a 10k variable resistor and a  6v or 12v relay coil to the trigger circuit next to the 1k pot and then upend your coil.put a lid on it and give your magnet a spin.If you are not clear with out a circuit diagram,i will put one up later in the week if you need it.Regards jonnydavro

Thanks Jonny, I`ve not built one of these before, so a circuit diagram and details on the Bifilar winding would be appreciated.

Hi.Here is the circuit i am using.The relay i am using can be seen in the picture 2 posts above this one and if you look closely i am only using the relays coil.The way i made my coil was i bought two rolls of 26swg wire.each one had 250grams off wire on and was 170 meters long.I wound these onto a spool i got which had speaker wire on it.I made it like this as it is easy if you start off with the same lengh off wire for each winding and it seems to work good.The standard Bedini coil and lidmotors coil should work just as well as other people have replicated with different coils.It is important to put both variable resistors in.I have the 1k one turned right up to 1k and i just leave it alone and adjust the speed with the 10k pot so i could replace that with afixed resistor but your circuits may behave differently so you want this as a tuning option.Another benefit of adding the relay coil apart from reducing the amp draw is that you can recover bemf from it with a diode and cap.Hope this helps regards jonnydavro.

Hi.I forgot to put the bemf recovery from the relay coil in so here is the updated circuit.
                                                                                                             regards jonnydavro.

@Xenomorph  what is going on in your last vid?

is the magnet needed at all or is the generation coming from the Bedini coil????

@jonnydavro thank you for the skematics and data....I am making an MK jt and will see if this coil can do the same thing with these magnets.
on the first video you picked up the top with the magnet spinning can the system be expanded vertically?

maybe a glass with another magnet above the first.

@Brownsville.That is an interesting idea.I will try it and let you know.Keep us posted if you have some results with the mkjt coil.
I don,t know if Xenomorph is a member off this forum.I will ask him or you could ask your questions on his utube vids.He is doing lots of  great work on this and his latest video's are very impressive.Here is are links to his latest video,s.

Thanks for the diagram, whats the value of the relay coil caps?
