I have  been getting ready to build A Bedini  motor

I  thought I had a few schematics of the circuits but  could not find them
It turns  out most of the circuits I have seen are on U tube.

Is this   a workable basic Bedini circuit?

I modified  a basic JT drawing  to make this  schematic

Are the  start  dots on the coil  the same in a Bedini as in a JT?

@resonanceman,

Something like this will run your motor.

Groundloop.

Thanks  for the schamatic

It looks  very well done and  complete.


 I see I was pretty close.
You  have  a pot and a resistor where I  just had a resistor.
You drawing  also has a neon....... I was going for as simple as possible  so I left that out.

I am  amazed at how  close it is  to a JT
I have no experience with Bedinis but I imagine  alot of my  experience  with JTs will help.

Edit

I missed the grain of wheat bulb
That is something  I have not seen before.
I am guessing it is acting  like  a resistor  .

@resonanceman,

The neon bulb is there to protect the transistor
against over voltage. If you disconnect the charge
battery then there is a high risk of blowing the
transistor.

The small bulb is like a RPM regulator on the motor.
The resistance in the bulb will vary with the
transistor base current. When the rpm increase
then the base current will be higher and the bulb
will "burn" more energy and the end result is that
the base current goes down again, thus keeping
the RPM stable.

Your JT experience will help. If you motor will not run
then just reverse one of the coils. Don't use Neos
on the rotor, use ferrite magnets. All north out. Also
get the coil as close to the magnets as possible.
A good rotor is the front wheel of a bicycle. Remove
the rubber tire and glue or use strong tape to hold
the magnets onto the wheel.

Good luck with your motor.

Thanks for the advice  .......I will follow it.............well for a while  at least.

Well actually probably until I get a rotor spinning.



I  am here to experment .........I have LOTS of ideas......some of  them are things I wanted to do with a JT but  didn't have the power.


Just curious do  you know  why NEOs should not  be used?
I am thinking that they are to powerful and make it hard to not over rev  the  rotor.
If that is the case I want to  use NEOs  as soon as possible.
I was planning on  making a  rotor with N and S up.......( EDIT secondary rotor this is not the primary bedini rotor  )   and putting  a few coils  around it.,....... this  should  make  a fairly normal alternator....... It should help  limit speed  similar to the way  you described the grain of wheat bulb  limiting it.

One thing I want to avoid  is cutting the input to limit speed.
I want to limit  speed by extracting power.

I have added an attachment ... i don't remember  where I found it but  it looks interesting.........except the reed switch part........reed switches  suck when it comes to reliability......
Page 2 has a scope shot of a signal......I want to make pulses like that with no reed switch.

I also wonder  why no one is using  both poles of the magnets........other  than the over rev problem.......
I read that black iron oxide is as close  as we can get to ferrite .......I have some on the way.......my epoxy resin got here 2 days  ago.
I think it will make a better core than nails........it may take some experimenting to get the right density.
I plan on making a C core and  trying to tap  both poles.......with luck  I should come close to doubling  the power out.

I also plan on trying to make  a  large toroid for JTs.......but  ......it is  iron powder.........so  I will be lucky to make one  as good as  I could buy.........but I can make them bigger........that may have some value.

gary do you want to build a motor?

if you do i will work with you public i have a fully duplicatable design that is self running ..

and if you want to build it i will build it with you public .. 

useing a basic bedini controller but my motor is NO BEDINI LOL 

its wayyyyyyyy better ...

regards ..

just push the thing ... : )

find some old vcrs ...

you can build it for cents ..

ist

the axel in this design is stationary only the wheel spins has 4 vcr bearings in it .. verry high rpm  like 30 000 plus

with this design you can even build the rotor of wood ..

and groundloop   

HAVE YOU EVER BUILT A MOTOR WITH NEOS ..?  IF THE ANSWER IS NO WHO ARE YOU TO SAY DONT USE THEM ?

btw gl a bicycle wheel is USELESS!   I RECCOMEND A SMALL WHEEL ...   speed !  you want high volt high freq from your aux coils then rectify it .. to a cap

i say go CORELESS IF YOU HAVE ENOUGH WIRE ...

PS forget the reed switch they just blow up .. or wear out in time ..   : ) 

never mind the low voltage welding incidents you will have and suddenly weld the reed contacts ....

if done right you can do it with an aa ... a welding incident  that is ....

and if you mount the rotor vertical .. gravity is on your side ....

hummmmmmm

IST

I have seen  a bedini made with a VCR head on U tube........it was very fast.

I  have a pretty good idea  of what I want to end up  with.

I am shooting  for a fairly small  multi rotor design
I am thinking  of  using a plastic  tube for an outer housing........PVC water pipe ........or acrylic tube  if you have the money and want to show  it off.

I am  thinking  if  the rotors are well made and on a keyed shaft....... I only need one  trigger rotor.......... I can add as many power rotors as I  need.........of course I will need  a alternator rotor or 2 ( to keep the speed in check ) ........ I am thinking  there will probably be a set ratio of power rotors to alternator  rotors........
The  fan motor mods showed me that  you can  use separate coils .


going  coreless is an interesting idea........ it seems with a Newman motor   the idea is to mostly  make big  coils..... what about  one  magnet on a rotor........and  one coil on each side of the rotor?
The magnet would have to have N on one rotor face and S on the other.......but I was planning on doing that anyway.......for many reasons.
If  the coils  were about 3/4 of the  size of the rotor .........but one side  of each placed near the  Axel  it might  just  work like a Newman...... the coils could be pretty thick
The  coils could also  be closer to the rotor than with a normal Newman.

I am thinking that a coil that goes around the shaft.......then just past the outer edge of he rotor  disk  would be ideal.... squeezing the coil  into a line ....... then  putting a line  of magnets from the center of the rotor disk out to  the edge....... 




I  agree on the higher speed thing............but I don't have any VCRs laying around.........and I don't plan on  anything like 30000 RPM
In  general a small disk  turns  faster  without  flying  apart....... I was thinking 6 in dia max........4 in may be better.
It depends on what parts I find to make it.

play with it see what ya get .. 

i just released my self running unit today ..

: )

it is also a neo zap switcher/ ampliflyer too 

lol

has 0 transistors ...  just push it ...

lmfao!

ist

look at this super basic toy ..  lol

http://www.youtube.com/watch?v=wf3MH1Bb3uU

: )

notice the sound of my motor toward the end of the demo ......  listen hard to the sound ...

i just love that video lol

i show how to make your motor accelerate ...   while under load .. hummmmm

the load can be the motor its self ...  hummm  it climbs in rpm while makeing a sparkie sound ..  hummm  it is feeding back after the transistor ...  HUMMMM A GAIN ....

via burnt out 33 ohm .. wich i made glow red hot in the demo b4 that one : )

IST where  is this 0 transistor thing?

Your bedini does go very fast .........personally  I would not  trust any kind of tape for holding  a motor together......It might work great for  proof  of concept but it  will eventually come apart........at 30,000 RPM that is not a good thing.

After  watching  your video I am thinking that my design should  be able to  hit speeds like that..... if I  go for the 4 inch dia  rotor
With  a bigger  rotor  it would be harder to reach those speeds and more dangerous.

I saw  you had  another video  with that same motor  describing a self running motor.  I did not  see a video with  the completed  motor....... did you make it?
If  you did  any work on it  I would like to hear about it.
What you described was alot like my plans.


```````````````````````````````````

No response about why NEOs should not  be used for bedinis.

Does this mean that no one here knows ?


gary

that video you watched GOES WITH A HOLE SERRIES  THE IST MINI POWERSTACK

YES I HAVE FULLY EXPLAINED MY DEVICES !

MY DEVICES ......

IT IS ASWELL MY DESIGN AS PER A LONG TIME AGO .. I POSTED A PICTURE OF THE DESIGN ... QUITE SOME TIME AGO ...

NONE THE LESS   

my powerstack  has quite A FEW TECKS IN IT ...

btw it is best you do your own thing ...

: )

the rest of my unit wont be public for some time ... : )

perhaps you should try things b4 you run your mouth ...

my tape works well

: P

william

I started to play with that motor yesterday ..  with coils i have LAYING AROUND ...
it is built with the switcher disc on the back of it now ...  it does not wobble ...  anyway .. as per yesterdays expairments ..  so far useing coils i had .. it will not run on 2vdc ...

hence a freqcon so i pulled in a big old tv  for parts ...

: ) 

Dn't know where to post, so write it here. For 3 years long watching at OU site, I'm asking self and others: Did anyone never try to build the device for household needs? All I could see here are only some models of BS. But it's well known that Bedini use the generator, one produce 10kw for his lab.

Well, the device itself has been built. It is called the "Bedini 10 coiler".
You can Google and You-tube with this string to find out how people
are coming along. I would much rather build a two stage battery pack based
on the biggest deep cycle acid/lead storage batteries one could find and
carefully buffer that output into a modern electric automobile LmNh battery of
26KWh. A line interactive 100KW instantaneous AC inverter and switch would
finish up the system. Only 1.5KW continuous power is require for the average
household current electrical needs. Because the battery pack has a high cost
currently, but is dropping rapidly, I doubt many folk have gone all the way yet.
The acid/lead storage battery needs to be only a couple KWh so it would
be economically replacable since that is where the power most likely is generated.
