Hi all,

If I flip my top coils (wires only) I get less voltage and current but the unit accelerates under load.

If I put them back to normal I get more voltage but I feel it acts like a normal
generator and slows under load

Is the power amount the same ? I understand voltage drops, and it should be logical that power drops also. But who said we are seeking a logical effect ?

Hi Romero,

I love my pinball machines

My coils are 35mm x 28mm with 12mm core size The winding is single 27g x 1300 turns
My core are ferrite tubes 20mm x 12mm with hole 5mm
the magnets are 25mm x 5 mm N35

Speed etc I will post tomorrow.

What is most interesting is the scope shot with ref to DC ground when I flip the top coils.
It looks like a DC Pulse train (square ware). I'll post pic tomorrow

Regards, Penno

Thank you Penno!

Ofc that is what he is saying . No really we should make a new thread and try to extract the basic and very short facts this huge thread has gathered.
If you study diodes you will understand that they are not all the same and putting them in parallel will logarithmically reduce their resistance

If fact this is a known effect to any doped silicon electrical component. The doping is not perfect, the impurities that separate + and - side can vary a bit from each component.

are you claiming that 0.8V volt drop across device A is somehow 'better' than 0.8V volt drop across device B?!?

what i ment is that by putting parallel diodes in the bridge rectifier the drop should slowly decrease (not liniary ). I thought you wrote 0.8 2 times by mistake. I have a feeling you wanted to ask something else
