Bedini DC Motor Hybrid

Update

Hi.I have had another look at my DC Bedini hybrid motor and updated it slightly resulting in very low current consumption and extended duty cycle at no expense to the battery.I now route only the bemf through the DC motor.This motor now runs using 3.5mA @12v.It will run on a lot less voltage as i have also run it with my joule thief and cap combo.
Here is a video and updated circuit.

Hi.
Mind, to try to to add 3 Diodes and a Transistior from left Schematic here ?
The 2 Diodes are add at the TriggerSide? Still not sure,, wich Coil is what, lol.
One Time i did break with selfmade Reedswitch, but it worked with a 2033 too, when i connect the Base to the Coil L1 directly for the Impuls.
At the Base of the other Transistor the Signal seems been weak or delayed.
And with the 3rd you can lead it back to the '+' or C

Hi joit,have you built this circuit and are you recovering bemf from the trigger coil?If so with what results.Regards jonnydavro

[Joit]

Yes,
But you cant really see it at the Scope it goes back into the Coil.
Since i did connect it, even, i control it with a Reedswitch at the Rotor,
the Motor speeds up, and i still can adjust it with the Pot very well.

It is a good idea to try and get something back from the trigger coil.Funny,i have come across this idea twice today,your version and comwarrior 69 on utube.He has a modified Bedini circuit which feeds back to the battery from the trigger coil.I will post the link for his video in the Bedini thread now thanks for sharing and your suggestions.

Hi,
Well, i put the Circuit in at 02-04, his Vid is from 02-08.
Seems he got something . But glad, that he did it.
My Thread is here
#1 & #47.
The first one is the basically Idea of it.
And i could improve few Coils with it.
I could even gain some more from a Coil what i keep beside a spinning Disc with Magnets, when i had it at like in the Circuit.
I only dont have Time right now, to play more around with it.

But i am sure, you can do more with this Combination.
Just need to switch the Diodes and the place from the Switch anyhow, that it fires at the right Point.
Or else, it will make a short at firing, or just dont work.
But i didnt burn anything while playing around, Mostly it only dont works.

[Joit]

Err. no, i am kinda wrong.
He did set it up some different, the Diodes looks serial and delayed with the Caps.
Just interesting, if he can gain Energy at the Batt, or if it is only for the Circuit.
I didnt watch it till the End lol.

[Joit]

I wonder about, that he lead it through the Caps.
I didnt have good experiences with that, mostly it sucked it out.
Do you think it is possible, to gain the Bemf through the Cap?
Well. maybe you can collect them there .. ?

[jonnydavro]

@Joit yes i think so.I will try to replicate when i have time as he says it works.Its worth a try
