This is a "motor" I made using Phun 5.28. I was playing with attraction to make magnets, but it didnt work out fine. I noticed that under specific circumstances the magnets rotate around each other. When I tried to glue them together with springs the gained more and more angular momentum. Thats when I tried to make a motor out of it.
It sure is a bug in Phun, but like Neo was told: "Some rules can be bent, others can be broken" :)
The motor has 0.4 Nm torque when halted, and 1.0 Nm when running at 15 rad/s. I verify this in the video with a motored hinge that runs in the opposite direction. I assume that when the angular velocity stays constant, the power of the motored hinge is the power of my "motor".
The trick of this motor is, that the attractor must not be FIXed together. When that is done, it wont work any more.
how to make this in the real live ?

@mikrofoner Like I wrote in the description: "It sure is a bug in Phun" - so if you stick to the thermodynamic rules, you simply can't rebuild it in real life, due the fact that it would be a perpetuum mobile...
