The concept of a power generator without moving parts.

Hey guys.

For some time now, I've been thinking about the concept of a power generator with a rotating magnetic field controlled by a 3-phase sinusoidal inverter.

Nicholas Copernicus stopped the sun and moved the earth. And what would happen if in a traditional power generator with a stator and rotor, all moving parts were stopped and only the magnetic field moved using an inverter? I once played with a car alternator, I powered it with another engine. In it, I disconnected the voltage regulator from the brushes and powered the rotor itself through the brushes from a regulated power supply. The effect was that the voltage generated on the stator did not affect the power supply of the rotor itself in any way, but only the resistance on the shaft increased due to Lenz's law. My conclusions led me to the absolutely certain one truth that it is only the speed of change of the magnetic field over time that affects the generation of current in the stator and it has absolutely no effect on the power supply of the rotor itself! If only we could simulate a rotating field and have the frequency of this field's rotation regulated over time, we would get rid of the Lenz effect and shaft resistance, because everything would be stationary except the magnetic field itself.
I am very interested in your opinion, suggestions on this subject, what else should be changed so that the system has a chance of success.

Yes that was one of the interesting aspects I also noticed. I have an old alternator that delivers 12 V and 36 A and when I energize the rotor with 12V, thru the slip rings, a maximum of 5A is "pulled" from my power supply. So we can judge that the power/energy developed in the stator winding/s does not come from the power source (the 12V and 5 A I was talking about earlier) but instead is coming from the movement of the magnetic field developed in the rotor that is inducing on the stator. The higher the movement (change of magnetic field relative to the stator coil/s) the higher the power/energy developed in the stator coil/s.

I remember that I powered the alternator rotor with a voltage of about 2.5v 1A, which gave about 2.5 watts at the rotor input. The alternator had about 200 rpm on the rotor. And at the stator output after the bridge I got about 10v 1.5A, about 15w. The stator load after the rectifier bridge did not change in any drastic way, literally single milliamps, but that could have been an imperfection of the measuring system. Without taking into account the power needed to rotate the rotor, I get COP-6. I still remember this experience fondly because I still have this alternator, maybe I will try to test it again in the future. I would like to know if anyone on the forum has done such experiments, or knows sources where someone has done such a project? It is worth considering and any theoretical comments are welcome here.

P.S.

I was looking for information about my generator concept and found a short video on YouTube by someone who describes exactly the same experience I was talking about. I took the liberty of posting a link to the video, I hope he won't hold it against me 🙂. It describes exactly what I mean.
