Permanent magnet motor

Great, Jim36.

I have a strange phenomenon too, in my experiment. But in fact it is not a strange phenomenon, it it induction, the way it is known to happen, just has not been used properly. When a small current starts in a coil, then this induces an increasing magnetic field, and this induces voltage. And how great this voltage is, depends on how fast the current is switched on. Very low current may induce quite high voltage, it's as simple as that. But this is not about permanent magnet motors.

Good luck with your project,

There is some interesting stuff around, I've heard of resonance switching before which may be linked with what you are talking about (switching on and off power without mosfets) as silicon switches are not meant to be as clean cut? This giving a very sharp increase in voltage and then somehow resonance is used to aid? If I can find the video I will post it for you.

Cheers

Ask yourselves why the "right hand rule" is important in EM wave propagation.  What are the more interesting dynamics in EM fields which cause a rotor to turn....and is it possible to employ PMs in a creative manner to accomplish same?

Or...more importantly...if all sorts of interesting geometric gear shapes can mesh at little cost, how might PM fields interact with one another in order to affect an electric current of sufficient strength to drive the process?

Resonance is just a word for something happening better in certain conditions. No, it's just v = L * di / dt , comes from the Faraday's law of induction. Initially current goes through the coil, because the coil has almost no resistance then, means almost no voltage either. The magnetic field is linear to the current. But the voltage, the force to create current, induced is the greater, the faster the magnetic field increases, notice the dt . It's in essence as trivial as that. And mosfet evidently switches fast enough for overunity. We may talk about it further in this thread http://overunity.com/14925/negative-discharge-effect/#.VW-iUTr52rM .

The following is only a pure speculation, not related to that above. I don't know that, additional energy, the reason for that may be electrostatic. So the strength of the current really depends on how fast the circuit is switched on, finally though the current goes back and forth, and the voltages settle how they should in the circuit. So to get energy from that, one also needs to switch off the circuit fast enough, and mechanical relays are not good for that. I have seen in a four plate capacitor, the voltage between two plates oscillates between settling, so i wondered why is that. So this is about that switching, of capacitors, and a possible reason why this may provide an additional energy. Would be simpler of course, because of capacitors only and no coil, but is less straight-forward and clear, what concerns theory. There may be something about current which we maybe have not been told, current may be in a way more dynamic as it is thought to be. But this goes already very far from permanent magnet motors.

Yes well, re (Aveaye) I'm not so sure this man's opinions are such to take as gospel ! he appears as far as I can see to be talking about resonance of a powdered substance on a table vibrated by sound till its mechanical resonance is reached. But is the device driving that frequency also at its own resonance, I doubt it very much and if not how would one reach a power factor of resonance ? now would we use parallel resonance or serial resonance, and what is the difference, (one hell of a lot) I might add, and what is a longitudinal wave and a transverse, one hell of a lot again, my advice is to look on Yutube for university lectures and avoid listening to half baked ideas on this comic strip !
