Mehess Motor

[billmehess]

Stefen, I have been running a working unit for up to 8 days producing a voltage which is being stored in a capacitor. This is a physical device not a pie in the sky or cad drawing. The device works I will be able to store enough power to rewind the motor. If I was running this on my 31 day movement I would have had a running unit generating electricity for 31 days.
Frankly I see the rewind as a enginering problem only.
The core of the device has been to find a way to generate power, store that power and all of this working in a unique way in such that I do not have to draw down on that stored energy to run the unit. This is the problem that all magnetic motors have, they must generate their own energy immed. to run themselfs.
Remember time is on my side. I have as much as 31 days or 744 hours to store energy.
Yes the capacitor is a 1/2 farad capacitor- very large physically.
None of this is theory , the device is working!

Hi Bill,
okay, if you really get to around 75 Volts on the 0.5 Farad cap,
then you have an energy of around 1400 Wattseconds to rewind
the clock.
In 10 seconds you can then use a motor that uses  140 Watts
of power, that means you could use a 12 Volts motor
that draws 11,6 Amperes for the 10 seconds...

But you will also have many losses during these days inside the
0.5 Farad cap, so if you will still reach half of the energy
level inside the cap that would already be quite a lot with all the losses
from stray resistances inside the cap.

What voltage level did you reach until now in the 0.5 Farad cap
after the 8 days ?

Great info-Thank you!

Running the device for the last 96 hours (4 days) has generated 8 volts in the capacitor. The capacitor is rated for 20 volts but no more than 12-14 volts should be stored.
The high  torque window lift motor runs on 12 volts dc and draws 8-10 amps under a load. I also have a lead on a company back east that sells dc motors exactly for the purpose I am proposing they are a clock parts company. I will call them Fri am to get their specs. I live in Oregon so its to late today.
Again thank you for your help it is greatly appreciated.

Remember the stored energy in the cap in
Wattseconds can be calculated as:

E= 0.5 x C x (Voltage)^2. So if it is 10 Volts on the cap we
have 10 x 10 Volts= 100  x 0.5 Farad x 0.5 = 25 Wattseconds.
With a 12 Volts motor you can just draw 2.08 amps for just 1 second !
So still not enough energy to rewind yet and you are only at 8 Volts yet!

At 8 Volts you are just only at 16 Wattseconds energy in the cap
and that will last only 1 second on a 12 Volts motor at 1.3 amps !
Not very much to rewind the clock.

Very true BUT I will have approx 16 volts at the end of the 8 days in one capacitor. With a 31 day movement I would have approx 4 times as much in 4 capacitors. This gives me 9-10 seconds of winding time.
I'm also looking at a standard weight driven movement. There are usually 3 weights that decend and run the pendulum over a 8 day period. It would take not much of a high torque
dc motor to rewind up the weights to begin the cycle on a continuous basis.
