Yes Romero I tried this yours circuit and it works great. I just wanted to make something similar with N channel Mosfet.
The main question from your experience is, what is better for driving pulse motor and BEMF recovery, transistor or Mosfet ?

JoeFR

Hi JoeFR,

if we are going to recover back to the same battery then mosfet is better but for best recovery we should use normal transistors and another battery and swap them or use a circuit to switch them automatically.
have a look at the picture below and try it, works great. if you have many batteries use them in series replacing Battery 2.
Before you start measure the voltage in both of the  batteries and calculate total voltage combined then after a period of time measure again and make the total again, you should have a greater total than the initial one.

Regards,
Romero

Hi Romero

Thanks for diagram. Today I was testing both No Hall driver circuits, yours with PNP transistor and modified with N channel Mosfet.
The main difference is that with yours driver I get BEMF spikes 150V, but with Mosfet driver I get 270V from drive coil.
I am now testing your diagram and charging battery from BEMF spikes.

Here is the modified circuit of No Hall Mosfet driver which now works very good and it is easy to tune:

Hi,
 I will try your circuit tommorow.
I think that D1 diode should be reversed, not to affect the input when charging batteries.

Hi Romero

Here are the scope shots from yours PNP transistor driver and N Channel mosfet driver.
With yours PNP driver I get negative spikes of 135V
With mosfet driver I get positive spikes of 270V so is D1 orientation correct then?

Experience is a hard teacher, it gives the test first and the lesson afterward.

Recent work.

The circuit posted by JoeFR works very well, anyway it needs more testing .

Hi Romero

I am glad that circuit works good for you too. Just one tip from my testing. Start the rotor with potentiometer P1 in middle position. When rotor gets to max speed you turn P1 potentiometer to zero ohms. The rotor will speed up again and then you use potentiometer P2 for fine tuning the speed and consumption. This is the behavior I get from this circuit.

I see you working on Caduceus coil.

Hi,
I am always readjusting after the rotor got maximum rpm. It works fine, no problems but I have not spent too much time with it as I am busy with other experiments.
I am testing caduceus coil comparing it with another coil, identical lenght of wire but wound in tesla bifilar style. So far I don't see much difference, actually bifilar works better so far.Caduceus might work better in different conditions, anyway playing with them I get to understand more how to use them for the Kapanadze project.
Very interesting is that if the primary got more mass (thicker wire or copper pipe) I get better results. Looks that the mass is very important in capturing envirnoment energy.

Best regards,
Romero

Yes Tesla always said it was the mass of copper that counted.

Test with a DC motor and coils powering the generator.Good results so far...

Hi Rom,

Good luck with the RG1.

Do you think you may ever reveal the makeup of the coil used in the speed up under load experiment.

I am still keenly trying to progress with this experiment.

Thanks, Garry

HI Romero,

How is the different between driving by DC motor and the drive coils ?

Thanks and Regards,

@garrym
there is nothing special about that experiment, with the right inductance and the right speed everyone should have that effect.Using one of the circuits presented before the speed up effect can be obtain at almost any rpm, the only thing that might be different is the value of the capacitor, depending on your coil output.
I might make another video with more details.

@M.E
there is not much difference having the motor but I need to see if it can be done without the driving coils, circuits...
Everyone will prefer having the simplest setup.
The belt used is not the best option, I will also try direct drive, having the DC motor shaft connected direct to the generator shaft.

@romero and everyone Would you please expand on what sort of results you got from this comment please . "Test with a DC motor and coils powering the generator.Good results so far..."
 Would like to see a video of speed up under load at all speeds as you mentioned to garry with more details thanks very muchly ron
 
would love to see more videos of you just experimenting with different ideas. thanks again ron
