One magnet no bearing Bedini motor

[jonnydavro]

Hi.I was going to convert a solar garden lamp i have to a bedini motor which would just sit in my garden hopefully running for 24 hours a day so instead off winding a small coil i thought i would take a relay apart and use that coil with an extra winding wrapped on,anyway when i took the relay coil out of the relay,it had an 8mm hole where the core had been so i put the garden Bedini on hold and thought i would try it as a satellite.
At first,the 6mm neo sphere was not very stable inside the coil.It would spin around inside the hole but not smoothly and it would stop quite easy but the voltage it generated was high so I then filled the hole with water and plugged both ends.This had the effect of dampening the unwanted oscillations of the sphere in such a small hole and it then ran nice and stable.I had noticed that adding water as a damper to some other satellites i had been testing was benificial.
This satellite relay coil is producing 34volts DC.Here are some pics.
@Retrod.Hi Dave.That is a very interesting experiment you show.We should be able to think of a use for this.
@Pirate.Hi Bill.I am glad you are trying the satellites.You will have fun with these.Let us know how you get on.
@Gadget.I agree with the other guys.It is probably something like they suggest or it could be even something as simple as your pot settings.With the snake egg,I have to have my 10k pot set at zero ohms and my 1k pot at 1000 ohms to start and then all adjustment is with the 10k pot unless your running at real low volts/amps and then the 1k pot is needed.Also try it aircore.Have you got a pic of your setup?
Don't give up.You will get it going.Regards jonny.

Why dont you use a sealed relay coil as the main self starter and add relay sealed pickup coils around it to harvest electricity without the need to spin a magnet to get the process started?

@Gadget, did you try reversing one of the coils? Another thing is make sure your diode across the base/emitter junction is correct polarity and a good one. Those two things can be show stoppers. The circuit has to work, I even made it work with tubes!!!
Tonight I made an astounding discovery, ok, it's not astounding  .

I check it all . I have build over 10 bedini's . these coils and circuits will work fine on a ROTOR  ,they wont work on one magnet . there is not enuff repulsion to hold a magnet up much less keep it spinning ? I want to buy one if someone is willing to make a coil that works .I have 100's of transistors and diodes  and lots of different relay coils and have reversed the trigger and coil wires turned it upside down sideways . three different coils . I give up on it I have wasted 5 straight days trying to do what jonny is doing . There is not enuff magnetic repulsion to stand a magnet up on my coils . even a lidmotor coil . . are you all using iron cores ? i know jonny and some other are not using nothing in the core . this dosnt make any sence as i can't see why the magnetic repulsion is so strong without a core. any core i have feeding 12 volts will just move a magnet a little bit straight 12 volts without a core ??

@Gadget,
  Looks to me you've covered the basics. My coil is air core but it is unlike the others as it is a 500 ft spool of twisted pair telco frame hook-up wire (22 tin plated solid copper). Any wire jobber could provide such a coil 'pre made' so to speak. When I use my coil I have to give the magnet a good stong spin in the upright position, and then it builds up speed. My scope is out of service so I 'listen' to the circuit and coil with a small amplifier connected to an induction microphone, this is also good to use for some basic troubleshooting.

@Gadgetmall:

I used welding rods at first and then noticed that it even works without them (aircore)

What magnet are you using ? Snake egg? Spheres? Cylinders?

It is key to give it a VERY fast initial spin so your hands are flying away off the strong jerk that you give it. Start with the lowest resistance setting on the pots (i sometimes have it literally to zero)
In my circuit it needs to have enough speed at first, so that the circuit can go sustain from there.
If i spin it too slowly then the ampdraw decreases to zero and the magnet stops.
But with 12 V it was easy to get it going, it will fly off the lid at that voltage once spinning.


What kept me from having an initial success i remember was that the magnet was too close to the core and got too much attraction from the metal to actually rotate. If you increase the distance it will work fine. In fact i got this working 2 feet away from the coil.
