Circuit setups for pulse motors

Also, my motors only capture back about 50% of the expended energy used to drive them without costing any torque to the shaft.

Well I took Runningbare's challenge of running the motor and capacitor hookup he described. I discharged the car battery to 1.75 volts and started the motor. The cap refilling the battery stays at around 13+ volts with a zenor diode inline. the battery doesn't lose voltage and the motor continues to run. I do think that the battery chemistry will keep it running for days if not weeks. With a new battery, I'm pretty sure I could run my motor for years without recapture of back pulse. However, this was one of my dead batteries from a car. It will only keep a charge of 8 volts, no matter what I do to try and recharge it. Thats why I figured it would be a great battery to test. I guess we will see how long it will run.

PS
If not recharging the battery, the cap will top out at 43 volts.

here is the video with this test setup. http://www.youtube.com/watch?v=yqEuYfpiT1A&mode=user&search=

Just to second guess any questions, this won't run on caps alone. It does take the battery chemistry to keep it going. So no free energy here. But the mA gauge is reading true. It is from the power input added to the recaptured amperage.

one last vid for the night, it seems to be running at the same input voltage of 1.75 at zero to .0015 amps from the battery. The chargeback has seemed to stop any more drainage, but this could be due to the lead acid chemistry going on in the battery. http://www.youtube.com/watch?v=aYIYevBajsc&mode=user&search=
