BEMF pulser

[Earl]

Hi Bob, hi Tao, hi All,

Just before going to bed, I took another look at the circuit and I think I see a simple way to get things to fly as we desire.  I want to take another look at it today with a clear head before posting my schematic.  If my analysis is correct, it will help understanding of at least two inventions.

Earl, that is excellent news. I'm intrigued about the understanding of two other inventions.

I unfortunately don't have access to my workbench during the week when I'm working at clients,
so I can't refer to my experiments until the weekend.
I think I may have been tapping in on the other side of the coil but I'm fairly sure I was connecting back to the +ve of the battery. The circuit may have been something like this...

Bob, I see you're trying to recycle the BEMF spikes TO THE SAME BATTERY.  We played around with a lot of circuits as part of the Bedini Motor.   I came to the conclusion that a transformer is the best way to go.

In your circuit once the MOSFET is turned off the inductor spikes in voltage realy high since it needs to drive the current and the other inductor can't just increase in current so quick.  But once they both carry the same current, the energy will dissipate in the closed loop formed by these two.

What I already had working was the BEMF of one coil being redirected into another coil. Unfortunately my notes on what I was doing, which are condensed into the original schematic, are infact wrong! What I thought I was doing is not what I was really doing. I'm away from my workbench so can't redo the experiment until next weekend or the next. I did this experiment a couple of weeks ago and had moved onto using capacitors as the resulting end point rather than the battery because I felt this would lend itself to be used in an oscillating manner.

Your comment has highlighted that a different battery could be the final destination for the BEMF - interesting idea. I like the transformer idea too.
