PMM Concept, does that work?

[dieter]

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. 


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
