Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

looks like a have a playlist for tonight

Hey Luc

Nice setup.  Try something here....

Use a full wave bridge rectifier for the flyback.   At first it might seem odd to do because that would mean that the input to the coil would be transferred to the bemf cap.  But once charged the caps voltage is mostly higher than the input. Supposedly this is what Bedini did and that was the explanation I understood.

It may help ease up on all that oscillation after switch off also.  There may be an oscillation in the coils after shutoff that are messing with the transistor circuits.

But when you get it back together, try the bridge and see what happens.  It may help get more into the cap and possibly help kill off the oscillations.

Here is the first part of the bucking field motor test bench build.
Sorry about the small product review lol.

Great job mate!

Keeping the two inductors identical is important. Good to have isolated flyback coils also.

Believe it or not, I had the same idea to use two identical dc motors as bearings generators to supports for the rotor if I was to build v.3

I have not demonstrated the direction the I cores are in my v.2 build. It's 180 degrees from v.1
The I core have more then twice the attraction pull then from v.1

See attached drawing I made for you.

Get rid of all steel

That would leave only air coils in the stator and a ferrite in the rotor.

So the residual inductance as Luc measured was changing roughly between 1.2 mH and 2.4 mH as it moves in the gap between the ON and OFF moments. 

That's only 1:2 inductance ratio between these "ON and OFF moments".

With air coils, that  inductance ratio would be ~100x larger.
Indeed, that would be very good for efficiency.

Humm ... that is interesting. Too bad there's nothing left to test

I'm not rebuilding this v.2,  it served its purpose of observing an even power input.

Thanks for sharing the idea.
