Hello everyone,
I have finally built the bedini motor with the circuit diagram the Daftman e-mailed me.
I must have wired something wrong because my coil gets very hot and my rotor refuses to spin.
I watched the video again and will recheck my wiring and magnets for north face out.
Sorry no video or picture yet.
I an using four magnets and a 12 volt car battery for my run and a 6 volt for my charge battery.
Anyone have any suggestions?
I worked very hard on this project, and I'm a little frustrated.
I will post a picture as soon as I figure out how to do that on my wife's lap top......my computer is in the shop.
Thank you for your time.
Eddie

Do you have an air core coil or iron/metal of some kind?
Insert metal core then apply power.
If that does not help try a larger variable resistor in the trigger circuit . If you are using a 5k pot then try a 10 k pot.
If that does not help ... the transistor could be dead ( shorted ) emitter collector junction. check with a meter.

| Eddie--- I had a heating problem on the last motor I built and found out that I had connected up my coil wrong. The start and finish ends of the coil need to be hooked up a certain way. The Daftman explains this in one of his videos. I should have paid more attention---it cost me a nice transistor. |

Hi Guys,
Thanks for the reply's.
I have a copper coated weld rod core.
I am posotive I have my coil wired correctly, i checked it over and over.
I am using a 1 k pot, I just bought a 2k today and will try switching it out.
Also I will trade out my 2n3055 transistor.
I didn't realize I could use a 5 or 10 k pot.
I watched Daftmans video several times and triple checked all my connections and verified north face out.
Good suggestions guys!
I must have shorted out the pot or transistor......
When I tap the positive wire on my run batt, it does kick the magnet away........butt the neon does not light when the charge batt is disconnected.
I have tried regular weak ceramics and stronger neo's and both together...still no spin...just funky wobbling.
Thanks for your help guys!!!
Talk to you all soon.

Firstly sorry for my absents from the forum been working a way from home and I didn’t have my pass ward with me. A shot in the dark, please check that you have the transistors B,C,E, are correct. Can you do video of your set up so we can have a look maybe we can see the problem.
Eddie would you mind if I moved this posting to
Technical help and Questions.

Hello Daftman,
Yes you can move this topic.
I have been working a lot of hours, so forgive me if my replies are several days apart.
I just found the cd with my camera software, so I should be able to post a video sometime this week.
I am using a 2n 3055 transistor,"the old style".
I've built the bedini circuit before, and I was very carefull about B,C,E butt I will recheck everything.
Thanks for being here for me guys, it's nice to have smart friends to ask for advice.

Hello Lidmotor,
I swear i have my coil hooked up correctly, but i may have damaged my transistor or pot with my beginner type soldering skills.
I did my best, but I do have a slightly large lumps of solder on all three connections.
I'm sorry guys, my camera software is not compatable with windows vista.
I'm really bummed out, I wanted so badly to post a video showing my motor set up.
I did a good job, I think the Daftman would have been proud of me.
I will post a message when I replace the pot & transistor.
I have my fingers crossed, I hope it will fix the problem.
Thanks for all the good advice everyone!
Eddie

| Eddie, Sorry to hear that you are having so much trouble. I did to. Soldering delicate parts I found out can be helped by using an aligator ("crocodile") clip to hold the part and helps dissipate the heat. Also use a low watt soldering iron. I have windows vista on one of my computers also and I hate it. I use an old notebook running Windows XP to do the videos. Somebody here should be able to help you with Vista to get it work the camera software. The pots that I started with all burned out quickly. They were Radio Shack carbon types. I later found out that they couldn't handle the current and switched to a wire wound rheostate type. These Bedini things are fun once you get em to run. Keep trying. Besure that the drive coil and magnet arrangement works by just using a reed switch as a last resort. This is just a pulse motor with fancy electronics. |

Eddie if you are having problems with transistor circuit try using a relay just for now, this will give you the chance to test your coils are ok.

Thank you Lidmotor and Daftman!
Again I apologize for my posts being so far apart, unfortunately I have to work for a living.
Thanks for all the great advice!
I have good news, .....I FIXED IT!! IT WORKS!!! HAPPY DAY!!!
O.k. had to get that out.
Here's what went wrong.
I am using the old style 2n3055 transistor with the two pins as the base and emitter.
I drilled two holes in an aluminum heat sink for the B&E and attached the transistor to it.
Long story short, my holes were too small and the B&E were shorting out or connected to each other.
I drilled bigger holes and "voila", the circuit works like dream.
I have built a very cool pulse motor, lidmotor check it out.
I cant tell you guys how happy I am that I fixed it.
I'm so very proud of my motor, I cant wait for you all to see it.
Soon I will begin testing and let you all know the results.
I did read 24 AC Volts comming from my coil!...could that be right?
Sorry for the links....I cant wait to figure out how to do video's again.
Eddie

| Congratulations on getting your motor to run!! I would have never guessed that the problem was a short in the heat sink. Now the real fun begins----figuring out what the heck is going on and what to do about it. That higher voltage that you are seeing was one of the first things that I also noticed. I stuck it in a great big capacitor right away and watched it go up to over 100 volts (watch your fingers)! It can make you dance around the room whether you want to or not. |

Hey Dodeca,
You got it right, !
My transistor was shorted out on the heat sink.
Good call.
Thanks for the advice, do you think a 10 k pot will give me better response as far as low speed vs higher speed?
Right now I'm using a 1k pot, and there is very little difference at 9VDC.
at 12 VDC it is much more noticeable.
Thanks.
Eddie

Hey lidmotor,
Thats hilarious!
Funny you should mention that, I recently purchased a 250 Volt 2900uf capacitor and I plan on charging it up and messing around with different ideas.
Sounds like I need to be careful and discharge it with a screwdriver instead of my fingers
Do I need to use a bridge rectifier before the cap or after or both?
In one of Daftman's circuits he uses the cap to drive a second motor, and or a light bulb.
I believe there in lies the secret to a self runner.
Thanks for all your help.

| Hi Eddie, I'm playing around with different kinds of capacitors now. Take a look at some of my Youtube videos. The big metal cap is 300v 30,000uf. The little blue ones are 2.5v 20F super caps. Each one does different things. The big one is the most fun. It makes the sparky sparky stuff. What comes off the back end of a Bedini is pulsed dc not ac so you don't need a rectifier. I have put these capacitors in every position you can think of and what I found out is that they don't "make" electricity. They just hold onto it in different ways. They work well with the different kinds of power sources but alone they just sit there and look nice. |

Ok if you want to test your cap’s use the BEMF from your Bedini motor then use that cap to run a second Bedini motor. If you get the right cap you will find you can run the second Bedini motor very successfully from the BEMF of your first Bedini motor.

| Thanks Daftman for the tip about using one Bedini motor to run another. Now that I have two good Bedini setups I think I'll try that. Months ago I did try using my first Bedini to run my old reed switch triggered pulse motor and it worked. I used an AM radio tuned to a null station to listen to the resonance and balance the two motors. It sounded good. I was trying to feed energy from the back end of the second motor back into the first one. As I recall the motor marriage was not good and it ended in divorce. Each one wanted more than the other one wanted to give. Everything ran great as long as the first one was having an affair with a sweet battery but once you seperated them then everything ground to a halt. |

The thing to look for is when you connect the second motor to the BEMF that the currant drain on the battery running the first motor doesn’t go up. And the capacitor stays charged at all times.

| Thanks for the great idea. It worked!!! I posted a video on my Youtube channel of the setup. I damaged my little voltage regulator by not watching the capacitor voltage. You are right about the current draw on the first motor to. One has to be careful that it doesn't get to high and spoil the whole idea. |

Nice video and replication of your work building one is good duplicating ones work brilliant.
Now going back to what i commented on in one of my videos.
This is where I don’t believe in the BEMF because if the BEMF was just that, it should not effect the power supply and it obviously does because when you drop a load on to the collected BEMF the current draw on the power supply goes up. Now in saying that, I am coming round to the BEMF thing but not yet convinced but in my experiments if you have very large capacitor array you can collect the BEMF from your first motor and run the second one with out draw on the power supply. I know if you get it all set up just right things will work as Bedini states, but for me there will always be a trade off.
This is the way I did my experiment.
I started the first motor collected the BEMF in to my capacitor array 2 47000 uf at about 300v. When the voltage in the capacitor was just above what I needed to run the second motor (12v) I switched the second motor on. It all ran fantastic with no extra drain on the power supply and the capacitor array was at about 13v. So my motor was running on the back BEMF from my first motor. Now what can I do with the BEMF from the second motor well I ran a small bulb but anything I connected just added an extra drain on the power supply running the first motor so I was back to square one.
Now both my pulse coils was driving the same rotor, so when my first coil fired the BEMF from that charged the capacitor 1 then the second coil fired using the power from the capacitor, then the BEMF from that coil charged capacitor 2 to run a small bulb. It would be interesting to find out if one could run a third coil on the same rotor from the capacitor 2 and so on. Anyway that’s my rambling for today.
A1 video. Please post for all to see on the forum.

I went ahead and posted the video here as a new topic. I hope that is ok. It took me 45 minutes before I figured out how to do it and still didn't get the picture to follow the link. I think that you are right about the BEMF. I'm not convinced that it tells the whole story. The way I see it, the BEMF and the high spike fly back voltage are two different things that somehow work together in this circuit to provide the back end energy. As I watched the two motors working and noticed the current draw it looked strange. I listened to it on my little radio and it sounded strange also. At one point the resonance syncronized and the speed of the second motor went up without the current going up. Then my voltage regulator died and all the fun was over for the day.
Here is a video that I posted on Youtube of one Bedini SSG motor using it's captured energy to run an almost identical Bedini motor. Daftman suggested that those of us with a working Bedini try this and it really works.

You did just fine you got the link up that’s all I needed.
I would like to move or copy your post into this thread for continuity, if that would be ok with you.
If you or anyone wants to post anything on the forum just post it with any links and I will sort it out for you.

| Thanks for sorting out that posting for me. Go ahead and move it over here if like. By the way, I really thought alot about what happened in this experiment. I don't think that the current draw should have gone up at all if the second motor was running strickly off of the back end energy of the first motor. It makes me wonder about the whole Bedini theory. |

Well you’re up to speed with the Bedini BEMT thing. That’s what I was trying to say in my video. BEMT seems to be a bit of a con to me but maybe we have not hit the right formula yet.
Just completed my new and last diagram for my new Newman motor, I will see if it works or not with this one and post the results.

Help! hot coil and no spin.
