PMM Concept, does that work?
« on: February 07, 2014, 03:42:03 AM »
Inspired by vineet_kiran's topic, I had a very simple yet interesting idea for a pm motor. I'd surprised if this is new, but just for in case, I declare it public domain.  8)


There is a disc, the rotor, with a pm at the edge, north facing in the direction of the rotation. Then at the stator there is a pendulum with  a pm, north facing towards the orbit of the rotors pm. So, if the pendulum is swinging towards the disc, it may push the rotors pm and make the disc rotate.


Now what is really important is the disc as well as the pendulum needs some weight, and the length of the pendulum should be adjustable, in order to obtain mechanical _resonance_ between the disc rotation speed and the pendulum speed.


As the disc rotates, the rotors pm is getting closer to the push-away-point, but the pendulum is still far away from the disc. Then, when the rotors pm reaches the p.a.p., the pendulum just bounced back to the disc. Now the following happens: The clash of masses is divided by two, the pendulum gets a little push and will keep on swinging, the disc also gets a push and will keep on rotating. Synching them, so the pendulum will not be pushed back until it reached almost it's dead point on the disc side, would be important.


so, all you naysayers, tell me why this wouldn't work please.


BTW. if it doesn't work, then forget the name thing  :)

Ok, that would have been too easy. It might work when the rotor pm is reaching the p.a.p. when the pendulum already started to swing back. Othetwise it will just reduce the swinging of the pendulum. Too bad the rotor magnet would have to go trough the entire magnetfield of the pendulum, including opposing forces. Well maybe there's an other way.

Thinking about it, maybe it wasn't wrong:


The pendulum has it's gravity based force requirement. By stopping the pendulum prematurly when it swings to the rotor (in order to push the rotor pm), we confront it with an opposing force. If that magnetfield based force is higher than 2 times the original remaining pendulum force, the pendulum can stay in motion. Interesting is, the magnetfield can be much higher that the pendulums gravity-based needs. Nevertheless, the weight of the disc must be high enough / just right.


Also, parallel shielding is needed to prevent losses due to non-parallel magnet interaction. And the pendulum needs to swing precisely on one axis, it may not swing in circles due to flexible materials.

is there a pict/digram for your idea?
it's will more easy to understand      :)

Not yet, I probably gonna make one later, if I still think it would work..
Of course it violates the 2nd law of termodynamics... I love that  :)

Ok, here's a picture. It's really simple.

the problems, 
step 3- 4-5, pendulum will swing shorter each cycle,
because when pendulum push disc ( with magnet ) mean pendulum wiil loose some of it energy,
(pendulum energy is moved to the disc), at the end pendulum will stop. here, we ignore friction of pendulum 

next problem, we know  "perfect pendulum that run forever is difficult to achieved"
i did't see the "magic" here.

next, how to maintenance both pendulum and disc always at perfect position in every cycle 
as there was no connection of them except magnetic field.

You're right. Well at least I have the ballls to confess that I was wrong.  :-\

No, thank you. I'm a naysayer too, usually. I just forgot what I know about pms for a moment.

 Don't give up so fast for there are many approaches that may prove otherwise. I myself have been learning more about making videos and I am going to start teaching videos of what you have to overcome and what designs to avoid and other things of interest from the gravity wheel point of view. they will be on my youtube station later on this year. At least that is the plan. 8)

Have a good one

 Here is a video for a little uplifting about wheel work.   http://youtu.be/Ny7O7bAn2uU

Several of my wheels didn't work either and I am not giving up. 8)

You're right, persistence is one of the keys. If Edison would have given up so quickly, we would still run trough the night with torches... No wait, Tesla already had those electrified neon clouds  8)
