Hi, due to the limitations and expense of the large Neo magnets and electromagnets to push the pendulum used on the Gram project I am changing the input configuration, that is similar to a water powered triphammer configuration. I will use 5 balance beams with 25 pound weights. One beam will re-set as the rest are falling.
https://youtu.be/Dskcjq-N_5w
using 6 balance beams, it should create a condition of 125 pounds will always be falling
If I'm understanding your device correctly 100 lbs. will be falling only on first half cycle. On the second half of the cycle it will be lifting 100 lbs. As I see it once the first weight reaches the bottom it would have to be returned all the way to the top before the other 4 levers bottom out. Which means it would have to go up at a faster rate than it went down. But maybe I'm missing something.
Hi, only one 25 weight resets at a time, maybe the example videos will help.

All the parts are fabricated I should have more to report in a few days. Cheers
Ok, one other point that your probably already aware of. It will take some amount of weight just to balance those levers. This will subtract from your expected 25 lbs. i believe. You may have to go with 30 lbs. or more to offset this loss. Unless you think you can live with it.
Hi, thanks for the help.

Your getting there slowly but surely. You say that your going with a PMA. Is that what you guys find works best for low speed applications. I see on some wind generator sites they speak highly of servo motors as generators. Have you any experience with them you could share.
Hi I will be test two PMAs. A hoverboard motor and a F&P washing machine motor. Both are three phase. At 600 RPM the hoverboard will produce about 10 amps at 12 volts and the F&P will produce about 50 watts at about 180 RPM. I will use a PWM circuit to limit the back EMF, copper loss, (I squared R) loss. Thanks for another option.
And thanks for the hover board option. I recently bought a 1 hp. 180 vdc brushed motor for my generator flywheel project.

Would be nice if that cinder block were to able to slide back and forth across the top of your lever. It's own weight would reset your lever. I imagine the amount of energy to move it would be the same. But would it be more efficient than the paddle wheel? Just a idea. But not a well thought out idea.
Or should I say a more efficient mechanism to move it.

Wiper motor with reduction gear, lifting 10 pounds easy. Thanks for the suggestion.
Very impressive project. It seems somewhat similar to a pump jack on oil wells.
https://youtu.be/Ll5tyKz0SbQ
gears
At 18:1 would it not just be 100 lbs. divided by 18. Which gives you 5.5 lbs. output force. As long as the resistance in system is zero. Not and expert but that's the way I see it. Or I'm am misunderstanding your question.
It may be to your benefit to just get a larger generator that can output some amount of power at lower rpm. You would then get rid of most if not all the parasitic resistances of your gear system.
Hi, thanks for the help. This is all new to me. Thanks again.
https://youtu.be/OCkeoOmQM1E
hi, this device is with no load, the challenge will be to find if there is a gear combination that will work 100 pounds falling force to over come the parasitic load of the gear train and still have enough power to produce more electricity than the wiper motor is using to lift the 25 pound weight. Thanks again. I will be adding more weights and then reduce the gears to see if there a combination that will produce more than 30 watts.

showing some improvement ??? starting to fabricate the cap dump circuit for testing
You are building a very impressive machine!
If you are doing a full disclosure, you could film your machine from some distance in order to give your fans a complete overview.
Do you plan to run your machine (once it is finished) only from capacitors between output (from some dynamo) and input (to the drive motor)? This would be a good way to show over unity (in case it is a self runner) and would free you from all measuring problems. Some batteries during startup would be acceptable.
I am looking forward to your results.
Greetings, Conrad
hi, thanks for the suggestion.
I just realized I can remove one gear set and replace the transmission braking load with the load created when generating electricity. :)
You will come to realize many things in the end. Have fun and looking forward to your next update.
Is the spread on your paddles still 60 degrees. If so do you see a problem with going to 30 degrees spread. If I'm thinking correctly this should give a 1 thru 6 on first half revolution. Then start back to 1 thru 6 on second half of revolution. This should allow you to keep both paddles. In my mind it would look like two half spirals. But I'm not sure how this will effect the stroke on your lever arms. You may have to lengthen the levers and cut down the length of your paddles to allow for the shorter stroke. Not sure.
https://youtu.be/E4xBtwM_F4Y
It would also allow you to place your weight further out on end of levers because of the gain in mechanical advantage on your shorter paddles.
Hi, interesting suggestions, thanks, nice to have options. Before I do anymore changes I should test it under load. Thanks again
Conservation of energy maybe a reason why this project could fail.

I am sure that many people have told you, that your machine can not be self runner because of "conservation of energy". And conventional physics teaches exactly that.
But you built it anyway and it looks like you have fun building the machine. The merit is in trying it in spite of the big hurdle to overcome. And if you can afford the build and if you do not become obsessed, no harm will com from it.

Hi, thanks for the input
conservation of energy applies to a isolated system, this configuration could be two isolated systems, continuing to test
How are those guides for your rack gear working out? In one your videos it looked a rack was sticking a little on way up.
I have to watch your videos several times before I actually hear what your saying. My eyes are to busy studying the different parts. In your last video you asked about optimizing flywheel. One thing to consider is shape. The bolts and holes in your flywheel will create more air resistance. At lower rpm it may not be significant but it's still robbing power. In one of my projects I have a 10" spoked flywheel. At 1800 rpm it was more like a centrifugal fan than a flywheel. I was able to shave20 watts off just by placing a steel plate close to the sides of the flywheel but not touching. So long story short a smooth flywheel would be a plus.
Hi, the guides are working ok, everything could be better. Thanks for the info about flywheel.
There is slop between the gearing of the rack and pinion. There is no sticking at this time.
I'm not sure why you want to swap the small blue gear and large gear around. Do you not have the room to move pma shaft over and have blue gear driven directly from large pinion gear.
Hi, everything fits. I can test at 1 to 9, swap the gears and test at 1 to 6. This is just version 1. Thanks for the help.

Just to clarify, you are lifting a weight with some acceleration a, and dropping it with the acceleration g. The hammer force difference is when g > a?
And a can be minimized using the flywheel in this case.
This is an interesting idea, if I understood it correctly.
Hi, this is just a basic idea. I have to measure how much electricity I can generate when the weights fall. Then I can replace the wiper motor with a pulse motor.
Unable to view your last video for some reason.

Hi, it seems to be working now. It needs improvement.
Are you making any headway with your project. Have been running back and forth offshore past few days. Don't have service 30 miles out, and too busy to post when around the dock.
Hi, it has been raining, waiting for dry weather.

Fabricated another manual PMA.

When you get back to your project you might consider changing wiper motor. It might make life easier to have a more powerful motor for cogwheel. Having the ability to change rpm across a wider range should speed up the tuning process.
I also believe that you will need to draw power from the pma at a constant rate. If you are charging caps and then discharging you will have a constantly changing load. This will make it impossible to maintain the timing of your cogwheel. As you know in order to get the max potential you will need all 5 weights falling while lifting 1. With a changing load you will have to increase and decrease rpm of wiper motor in order to maintain proper timing.

If your not already familiar with the formula this may be of help.
