Mehess Motor

Hi Group
I'm still working on the device. Here is where I am at and I ask the help of the group to proceed further.
The basis of the design is to via a clock pendulum system to swing magnets through a coil to generate electricity. I use a 30 day clock pendulum. I am charging up 4700mf caps one at a time. My device will charge up the caps to 250mv in one minute. Thus in 1440 min. (one day) I would be able to charge up a series of caps to 360 volts. Of course the problem is that my total capacitance has been reduced by 1440. There in lays the problem.
Also in 30 days at 360 volts per day I could store as much as approx. 10,000 volts but agin at a greatly reduced capacitance.
The uniqueness of the device is that it needs to be able to rewind itself from the stored energy in the cap system.
I am using a car window motor (low speed high torque) that under the load of rewind the motor uses 12volts at 4.5 amps (54 watts)
It would take only 12 seconds of run time in a 30 day time period to rewind the clock to keep the device running continously.
In a 30 day time period there is 43,200 minutes obviously to charge up that number of caps individually is not really practical. One would have to charge up a smaller number and then "dump" them into another cap to charge up another sets of caps to a higher voltage rating.
Interesting enough  I have a one farad cap system composed of 214ea  4700mf caps that when charged up one at a time exhibits a voltage drain in 30 days of less than 7%.
Anyway still clunking along on this. Thanks for the interest.

Well again the total required to rewind is to be able to run the motor for 12 seconds per month. 12 seconds will rewind the 30 day movement 9 complete revolutions which will totally rewind the clcok mechinism. To do this the following is required:
I would need to be able to store 36 volts in 214 individual 4700 mf caps (214 caps=1f.)
Formula is a follows:

energy in watt seconds= capacitance(in farads) x voltage squared all divided by 2

energy in watt seconds= 1f x 1296 divided by 2 = 648
Motor draws 54 watts under the load to rewind the clock so 54 devided into 648  = 12 seconds of run time.

Again the problem is how to use all this electricity I can generate and store
to run the motor.
Also I have just completed a new  coil  system for the device that uses 9 magnets into 9 coils instead of the 2 magnets into
2 coils.  I can now generate about 1200 mv per minute.
In 30 days I can generate one hell of a lot of stored voltage. But agin the problem is that I need to work out a way to drop these individual caps into another bank fo caps to increase the stored energy (or capacitance) per capacitor. Lots of voltage though.

Hey Bill,
Good to see your still working on the idea. I'm currently working on a capacitor switching issue with a pulse motor. Once the switch is figured out, I would be happy to share it with you and all those that follow these forums. From what I've read of your new set up, you running a 12 volt motor at 4.5 amps. 12v * 4.5a = 54 watts , 54watts/60min = 0.9 watts per min, 0.9watts/60sec = 0.015 watts per sec, giving a total of 0.015 * 12 = .18 watts to run for 1 month. Quite impressive. Are you sure the motor is only drawing 4.5 amps while it is rewinding the spring, has this been measured.

I think you might be better off storing you voltage in a mechanical device such a flywheel to rewind you clock. I am currently running a motor at 30mA at 5 volts (.03amps * 5volts  = .15 watts, which is slightly less then what you are consuming with your motor. The output from the collapsing magnetic field is anywhere from 200volt (at 1 micro farad (in 3 sec))  to 17volts  (at 1.5 farad (in 240 sec)).  Here is the link to the motor. http://www.youtube.com/watch?v=UDOm7BWC0dY&mode=user&search=
I believe that our work could be combined to complete this project.  And even while I'm capturing this voltage a flywheel could be spun up to speed to rewind the clock mechanism.

I guess I'm a little confused as to what you are saying. Under the load of rewinding the 30 day coil in the clock the motor draws 4.5 amps (12 volt motor.) which is 54 watts your device is drawning .15 watts. Again my problem is that I can generate and store a lot of energy over the 30 day cycle. How do I get x number of kv down to say 36 volts per 50volt 4700 f capacitors.
In other words 214 caps each rated at 50v 4700f charged to 36 volts will rewind a motor drawing under load of 4.5 amps will run for 12 seconds. This will totally rewind the clock coil.
As I have said many times out of 2,592,000 sec. (# of seconds in 30 days) I only have to run the motor for 12 seconds to make this thing
work. That being defined as a device that will self charge under its own power. I have the voltage but not the current, possibly a converter system could be employed.
Like I said I will keep plugging away.
