self charging electric car (prototype 1)

@dreamyear: besides the circuit diagram problems, the motor is not on all the time. This will make it weaker (less torque).

u can do this with realy but i prefer this way

Very interesting experiment, keep up the good work! Cheers

Hi dreamyear,

I would like to show you a schematic which could be used and you may wish to hook up your DC motor as shown here:
http://jnaudin.free.fr/ossiemotor/images/ossiemotorv13.gif   from Naudin site: http://jnaudin.free.fr/ossiemotor/indexen.htm

Your DC motor would connect to the right hand side to replace the seriesly connected air core coils and your two mechanical switches would be modified in timing: BOTH would be needed to switch ON at the same time and then OFF also at the same time. In the simplest case you may wish to position the rotary prongs at 180° of each other (like when a clock shows 6 o'clock for instance: the minute-hand and the hour-hand form a straight line and at their ends they touch the stationary contacts).  In the original schematic Naudin and Ossie used reed switches that were triggered by control magnets simultenously ON or OFF.

This way all the spikes right after the switch-off of the two switches can immediately go back into the battery via the fast diodes which are permanently hooked up, they form a full wave diode bridge.

As conradelektro noticed for your setup, your DC motor has a smaller torque and this will be so with this suggested setup too BUT for the test purposes this does not matter, once you are able to measure the power taken out of the battery and to measure the real torque.  OR if you have an oscilloscope, you could see the current pulses going out of the battery and going back into it (this latter is seen when the switches are just switched OFF) as I described in my previous post above so that comparing the two pulses we could estimate power levels.

If you build this setup, try to use it first without the puffer capacitor shown in parallel with the battery and later connect it. Of course you do not need to use the series 22 Ohm resistors either.

I'm sorry, I just tried your circuit and the capacitor is charged by the battery and no L1 (motor) flyback goes to capacitor.

i'm sorry... use bride rectifier instead  single diode.............are u serious?.. i get  50v back emf  with 24v dc mtor

Hi dreamyear,

Do you happen to have an oscilloscope?  If yes, please check the current waveform across a 0.1 Ohm power resistor, just insert the resistor in series with the negative pole of the battery and show the waveform across it.  I indicated in your schematic where I think the resistor.

Thanks, Gyula

sorry   i do not have   oscilloscope
