hammerFall gravity powered generator

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.

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.

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.
