Gravity Motor Patent 7/10/08

[mondrasek]

Okay.  At work right now.

I finished assembling 4 more mass switch modules for my set up and mounted them this morning.  My wheel now has eight total.  I could notice a big difference in that it took much longer to slow down since the weight imbalance in now larger and closer to the wall force need to overcome for the Gravity Motor to work with perminent magnet stators.

My mass switch magnets were firing way harder than needed, all the way to the top of the 8 1/2 inch long guide tubes on ones where the tube has the least amount of resistance due to my whistle slots having burrs and other irregularities due to my hand built tubes and latches.  So I tried lowering the stators to decrease the wall and only kick the switch magnets up high enough to latch.  The results were fantastic!  I believe it is possible to make a unit run with just these 8 mass switches if the tube and latch designs were low enough friction.  Having the ability to adjust the height of the stator magnets would make it very easy to dial in.  Unfortuantely my build is not easy to adjust (I have everything screwed together with wood screws and have to move things by relocating those).

MO when you get it dialed in, try to shoot some video of it with whatever you have. Between Aaron and I we can convert/encode it into some usable format. Even my digital camera can shoot digital video if you need to borrow. I have a cheapie digital video cam you could use as well didnt think of that, we got tripods and everything you prob need.

I build them myself, generally because nobody will believe me when I tell them their ideas won't work. So I try to get around the objections of improper materials, inaccurate builds, and overenthusiastic designers who only see what they want to see, by building one myself to the designer's specifications or with obvious improvements or buildability mods. Unfortunately, even when these things are done correctly, the devices still won't work...
Except for one time, when this technique backfired on me...but that's another story altogether.

Please, do tell... You're not hiding something from us are ya mate?

This represents about 4 1/2 hours work (I don't use CNC, it's all by hand) and about a quart of WD-40.

Really nice work TinselKoala

Think you will find using a old Bridgeport mill, and doing it by hand takes a lot more skill than using a CNC machine, well done.

I thought of using an external magnet or magnet pair, rigidly mounted outside the sliding magnet's tube, to act as the latch. IF done properly it should return the energy taken to drive the slider into the latch field.

Now that is weird I was thinking this while driving up to work this morning.
At first I thought magnets and then my mind drifted to using steel plates on the end of tubes and rubber stops between to make the flux less.

Then it is just making sure the stator is strong enough to push it away.

TinselKoala , is this AL?
