Accelerating motor-generator selfcharging capacitors without any batteries

[DreamThinkBuild]

Great find Stefan,

Is this the basics so far(minus control circuitry)? I wasn't sure of the caps or how the generator feeds the caps, feel free to fix/notify if this is in error.

- 5x 1F(?), 2.5vdc caps

- 1x 20mF, 16vdc caps

- Prime mover is his modified "Stargate" DC motor, running off three 1F, 2.5vdc, 7.5vdc total

- Generator is a low rpm axial flux generator for/from wind turbine being fed back into entire cap bank?

Hi Tinu,

I have the same question, about the charging of the top cap. It's going to charge quick, so is he just measuring the quick charging of the small F cap added to the slow discharge of the higher F caps? The real test would be with a load to see if the top cap is really just inflating the reading.

What I do find most interesting with this setup though is the speed increase, which is hard to get with any kind of self generated feedback loop.

I think the 16 volt cap is a 120,000uf.  Also, the star-gate motor is assisted by a built-in Wankel style magnet motor with a single coil pulsing once or twice per revolution.  The Wankel is built around the outside of the axial style generator that is located in the center of the generator box.  With just the Wankel running the generator, he  says that it will run for an hour or two.  The strange thing is that it speeds up after he manually starts it, but then it runs out of juice in an hour.  That does not make good sense to me.

Yeah, i think the wankel motor Does the major spin of the rotor and the pulsing coil assist only to reset the rotors starting position...


What do you think if he put more caps in the rail, would it spin longer or maybe will not stop?

Hi DreamThinkBuild,

You don’t need another test. It’s already done in the video: the voltage clearly drops (albeit slowly) due to the very small load attached (the internal resistance of the DMM, probably 10MOhm).

On the second issue, imho it is not really a “self generated feedback loop”. The feedback current quickly goes to zero (due to the rapid charging of the terminal cap) hence rapidly decreasing counter-torque, hence acceleration. Meanwhile, the other 3 much larger caps of 1/3F at 4V or so have enough energy to temporarily sustain the motor.

Best regards,
Tinu

Hi Tinu,

Thank you very much for the informative reply. The increase in speed makes sense now.

Hi Liberty,

Thanks for the update on the cap.

I think I see why he is losing charge over an hour or two from Tinu's explanation.

Once the top cap is full the feedback current is near zero, the motor will still be drawing from the three motor caps though.

As the three caps slowly lose charge the fast charging cap is acting as counter balance to the lost charge on the three motor caps.

Once a point is reached the top caps will not be able to sustain the current draw from the motor and lost charge from the three motor caps then it stops.
