Hi Marisuvic

Follow Gyuala's advice for sure - he is doing what I suggest in isolating the backem/recoil when it hits load via transformer is how I see it...I am doing it by isolating via dumping into caps and load with the timing when they are on or off in relation to the other - all the different components and events....

anyways that problem you got wtih the pos lugs and sparks and neg side doesnt (other way around?) I got that happening too - I traced it to the way transistors or mosfets always have that source lead connected to either pos or neg of circuit if NPN or PNP and you dont get that problem with solid state relays or reed swtiches or mechanical timing.....
keep going and dont stop

Hi Kone Thanks


.if you want the same amount of power and rpm as you have now, then do a cluster of pulses say 4 or 5, and pull out bemf/recoil after each one too (!) Last thing bill Muller told me is you wouldnt beleive the power you get when you do a cluster of 4 or 5 pulses...


You mean something like in this scope shot. I made this with Arduino controlled pulse motor coil driver:

Hi Gyula

For now i'll try to adapt this circuit.The secondary of transformer should go to the battery

Hi Marius,

Ok but you need to feedback to the 555 some sample from the output to make it stabil, otherwise the whole setup can slowly run away when looping.  See this link how it could be solved for the 555 by a transistor between on pin 5 and ground BUT you need to use here an opto coupler to maintain isolation the transformer would insure. The input diode in the opto coupler would be driven from the secondary coil's rectified DC ouput via a resistive divider and the output photo thransistor of the coupler would ge to pin 5 of the 555 and its ground. See this link for the principle, without the opto what you would need to adopt into the circuit: http://www.dos4ever.com/flyback/flyback.html  and go down to 1/3 of the long page "A simple boost converter high voltage supply for NIXIEs"

Good luck,

Gyula

Here is my new video after long time where I am testing the No Hall Pulse Motor Mosfet driver and BEMF CAP Charge and Discharge to load ( light bulb ) circuit Arduino controlled.

Joe, good work. See if you can drive a second driving coil from the output and measure power ratio in/out again.

Hi chalamadad


Yes this is the next step.
Today I made a little modification and I get 1,27Wats out from BEMF.
I will post new video soon and I hope to show better results.
