just finished my first bedini energizer and already problems :(

just finished my first bedini energizer and already problems

1. VCR Motor bearings, 3 inch wheel diameter.
2. CD player lence magnets. total 6 magnets. Easy to obtain and much power full in small size, 7mm X 7mm X 1mm
3. 32 turns coil.
4. single Ferrite core. 8 mm core diameter.
5. Power supply 12V and 5V 5Amps.
6. Transistor TIP122.
7. Diode 1N4007 also tried with 1N4148.

1. How much turns require to start the motor ?
2. Darlington paire transistor is suitable?
3. Pulse pick up coil gives only 0.01V AC max when rotor is rotated. I think less voltage becouse of less number of turns.
    is this the reason motor is not rotating?
4. Ferrite core is suitable ? ?

Tried with reed relay, it is burned (by mistake), and it requires very close distance to operate.

hi there

2. Are the CD Player magnets neodym, ceramic....?
3. 32 turns? That's too little I think, my bifilar coil has around 1000 windings.
4. Not sure about ferrite core, I have thin welding rods packed together.
5. I use 12V, when I first used 6V it was not enough. And ye 5 amps that's more then enough for a small setup I think.
6. Not sure about the TIP122 transistor, I use 2N3055
7. I use only 1N4007 diodes in my setup.

1. You mean how hard do you need to spin it? My rotor needs a light spin and it starts to pick up speed by itself.
2. I'm not sure if a Darlington is needed in this simple setup.
3. By looking at your pictures I see that your coil is not installed, what is the distance between the core of the coil and the magnets ?
4. I'm not sure.

Another thing I found today about stan mayer electrolysis, CFL Coating, Conditioning of tubes

"Another variation on existing CFL technologies are bulbs with an external nano-particle coating of "titanium dioxide".
Titanium dioxide is a photocatalyst, becoming ionized when exposed to UV light produced by the CFL.
It is thereby capable of converting oxygen to ozone and water to hydroxyl radicals,
which neutralize odors and kill bacteria, viruses, and mold spores."



2. Are the CD Player magnets neodym, ceramic....? 
Dont Know, But it satisfy this condition  Neodymium magnets are very strong in comparison to their mass, but are also mechanically fragile. Some steel kind of coting is there on outside and inside very very fragile. black,gray color.

3. 32 turns? That's too little I think, my bifilar coil has around 1000 windings.
I will try this soon

4. Not sure about ferrite core, I have thin welding rods packed together.
  When I have pulsed coil by hands wheel spins, current is too much...

1. You mean how hard do you need to spin it? My rotor needs a light spin and it starts to pick up speed by itself.    Without coil once weel is spin it rotatels at least 50 time, bearings are somooth

3. By looking at your pictures I see that your coil is not installed, what is the distance between the core of the coil and the magnets ?  I am holding coil in hands, first trial run, distance can be adjested..

I think that's the main problem. I have not seen any SSG with less than 450 windings. Most people recommend more than 850 windings.

Hey, seems about right time to chime in...

What kind of wire are you guys using for the coil?

I tried to make an electromagnet (to just get my first motor to spin) and I used 26awg (27swg) enameled copper wire , 350' onto a ferrite core.  The resistance I measured was 20ohms.  But when I run 12V through this , there is no magnetic field.  The copper wire just gets hot.  Any ideas?

Here is a picture of my elektromagnet:


Thanks
