Circuit setups for pulse motors

[Nastrand2000]

Well after two continuous days of allowing the motor to run on 1.5 volts, trying to charge a 9 volt battery through a zener diode, I found little to no gain in voltage. I had been charging a 50 volt cap that would fill to around 12 volts above the battery voltage and there it would sit. So I conclude that Gyula was correct about the use of the zener ( that it would consume the excess energy). After removing just the zener about 4 hour ago the voltage has risen from 7.5 to 8 volts. I will let it run for another 24 hours with this setup (unless my wife decides to turn the experiment off without my knowledge) and see what the voltage will climb to. The motor is drawing .005 amp times 1.5 volts = .0075 watts.

After letting the experiment run for 22 hours, the battery only climbed to 8.15 volts and it reached that after 4 hours into the experiment. So I think I need to change my charging tactics. I believe if I use a capacitor of a certain micro farad and charge it to a given level, I should be able to graph how fast it gets to that level in a given amount of time. This should help to quantify my findings, and give better answers to the questions you all might have.

If you guys would like some parameters set for the following experiments, please set them forth. For instance; wattage input, voltage input, amperage input, and distance the magnet is from the coil. Any other parameters are welcome. This thread is for you guys, also if you would like me to set up a different motor (say one conforming to your own, ferrite or neo mags) I would be happy to.

well I finally got rid of having to recharge 9 volt batteries for volt meters. I wired one of the meters to a 9 volt transformer, so no more misreads from battery insufficiencies. I plan to do this for the rest of the meters in parallel with the transformer. Then I  won't have to worry about meter incompetencies due to a low battery. The transformer is 1 amp max, and 10 meters would never even reach that current flow.

nice jase.

I just finished testing my setup. With 4 coils and two halls (2 coils per hall) I am filling a 8000uf 80v cap to  over 40 v and still climbing. I unfortunately cooked one of my transistors just as I was setting up the camera, found the fault and I'll get a new transistor soon.

Jase when you charge alkaline (non rechargeable) 9v, do you charge to around 11 v, so that when it is disconnected the voltage settles around 9? Have you done any tests to see if the battery drains similar to a new 9v under load? I am going to do some tests at the old paintball field I used to work at. They have buckets of dead nine volts and I'll charge them and see how they perform in the loaders against fresh batteries. Should be interesting
