just finished my first bedini energizer and already problems :(

[prometei]

Hey every1, I've been reading this forum for a while now and finally have decided to post.

Today I glued the magnets to the skate wheel on my bedini energizer, hooked everthing up but it did not spin or anything.







When I hooked up the primary or the secondary battery (don't remember which one first) for the first time to the circuit, the neon bulb had flashed. I gave the wheel a spin and nothing happened, I checked all the connections again, reconnected everything, (neon bulb did not flash this time) tried again and still nothing. Then I just took the battery and hooked it up directly to the power coil with a switch in between and the neon bulb to the trigger coil.



When I was pressing the switch the wheel was turning 45-90 degrees, so the magnetic fields were OK, as I was releasing the switch the kickback spark was lighting the neon bulb trough the trigger coil, so bassically it is not a problem of the coils or wrong magnetic polarity, or at least it looks like that to me.

Maybe I fried the transistor 2n3055 when I was soldering one end of the neon bulb to the collector, it did not want to stick so I had to keep the soldering iron longer on the end of the neon bulb and the collector then I probably should have.



I'm also using a IN4007 diode instead of a IN4001.

The power coil is wound with 0.6mm copper wire, the trigger coil with 0.4mm copper wire, approximately 1000 turns on a 8 cm long 1 cm wide PVC pipe with four thick welding rods inside.
I tried the set up with two 6 volt and two 12 volt lead acid batteries.

I'm linking pics of my energizer and the schematic on which it is based (i omitted the small 25ma bulb).



Thanks for any help !

p.s. I'm going to order some magnetite powder (Fe3O4) and some regular iron powder to use instead of the welding rods.

Hi!  Nice looking motor!

Okay, so the first thing I would do is try to get the thing working in "standard motor" form.  Just use one of your coils, and use this schematic.

If you can get the thing to spin, then the problem is in your Bedini circuit. If it doesn't spin, its your coil or your motor.   Btw, One thing I noticed with the skate bearings is that they are not nearly as good as ceramic bearings, even ABEC-9 skate bearings.  But ymmv.  Also your power transistor might be bad, could be a good idea to test that as well.

Hi prometei

Looks cool !

3 things;

1 - ALWAYS have your secondary battery connected. If you don't and your neon flashes you will damage your 2n3055 transistor. If you bought the transistors on Ebay there is are chance they are fake and will damage even quicker 
2 - Check your potentiometer resistance. It looks like your using a 1/2 watt pot. I have blown two 2watt pots in the past using exactly the same circuit and winding wire diameters.
3 - Completely fill your core with welding rods. In picture 2 it looks like you have some large gaps. Any copper coated mild steel welding rods will do for learning

Here is my first youtube vid, you will recognise the circuit diagram http://uk.youtube.com/watch?v=yenJtDzogiE

One other thing, It is better to have magnets that, at least, are the width of your coil.

Other than that, chin up old bean. You have just started down a VERY exciting path.

BOURNE thanks for the video  I'm very Impressed   Chet

thats a sweet vid , im very tempted to build one my self.
