The bistander thread

[Rakarskiy]

Bistander, I know the technology very well. And this technology is not Holcomb's alone. It's just that he built devices and demonstrated them, even though he didn't understand all the subtleties. His commercial side is of little interest to me. I am an advocate of open technological code. The task is to bring it to the ability to perform by a garage master. Yes, we do it. When I explained to an engineer that the excitation current of the rotor of a synchronous generator should decrease when the phase load is switched on, he sort of twiddled his thumb at me. We had this moment of argument. But when I myself recorded this drop of current in the excitation circuit, I was surprised with the declaration that this is an unexplored effect. The question is, is it so? So stay in your illusions, I always bring everything to its logical conclusion. In any case, I do not hide anything from anyone. The ability to perceive my information lies in the preparedness of the reader. This is a simple synchronous generator system with magnetic poles.

So prove that it can produce more real power than it has input.

Concerning your comments on the excitation current, I checked with an on-line source. Here is that conversation:

Hello. My question concerns a synchronous generator running at constant speed and a load is applied across a output phase. How does that affect excitation current?
ChatGPT said:

Hello, bi! In a synchronous generator, when a load is applied, the excitation current adjusts to maintain the output voltage and balance the system’s power requirements. Here’s a closer look at what happens:

Increased Load Demand: When a load is added, the generator's output current rises to meet the demand. This causes a voltage drop due to the impedance (especially reactance) of the generator windings.

Voltage Regulation: To maintain a constant terminal voltage despite the increased load, the generator’s automatic voltage regulator (AVR) increases the excitation current. This boosted excitation strengthens the rotor’s magnetic field, helping to counteract the voltage drop caused by the load.

Stable Power Factor and Efficiency: If the load is inductive (common in many systems), the excitation current may further increase to counteract the phase shift and maintain a stable power factor. This minimizes reactive power effects and ensures efficient operation.

In summary, the excitation current rises with added load to maintain the generator’s voltage and compensate for any reactive power drawn by inductive loads.

Thanks, as I suspected. What if there is no regulation, just a constant voltage across the field?

Hello. Did you see my question?

ChatGPT said:

Hello, bi! Yes, I see your question now.

If the synchronous generator's field is supplied by a constant, unregulated DC voltage (no automatic voltage regulation), then the excitation current remains fixed regardless of load changes. Here’s how that affects the generator when a load is applied:

Voltage Drop: As load increases, the output current also increases, and the internal impedance of the generator (particularly its synchronous reactance) causes a voltage drop across the output. Without regulation to boost the excitation current, this voltage drop will not be compensated. Therefore, the terminal voltage will decrease as the load increases.

Reduced Voltage Stability: Since there's no adjustment in excitation to counteract the effects of load, the generator’s output voltage varies with load demand. For instance, under heavy load, the output voltage will be significantly lower than the no-load voltage.

Power Factor and Reactive Power: If the load is inductive, the generator's lagging power factor worsens the voltage drop. The fixed excitation field is unable to compensate for the increased reactive power demand, which would typically require higher excitation to keep the voltage steady.

In short, without regulation, the generator's ability to maintain a steady output voltage across varying loads is compromised. The generator will experience a "drooping" voltage as the load increases, affecting the stability and efficiency of the power it supplies.

You said:
Thanks. This confirms my interpretation of theory. That's all for now.

You're very welcome, bi! Glad I could confirm your interpretation. Feel free to reach out anytime—I'm here to help with any more questions.

Hello Ufopolitics, I hope you read this,

I see on your forum your recent post concerning armature winds.
https://overunitymachines.com/index....7d14f3102c351e 72a5ffd2cc
It appears to me that you illustrate a duplex lap wound armature.

Multiplex armatures are old school and Google was of little assistance. In fact, it brought up several website with descriptions of duplex lap which were wrong. I thought I would need to dust off a old textbook to find a correct explanation and diagram to forward to you. But I did find a video that is correct.

The duplex winding pattern does provide two distinct circuits however during rotation, the brushes always connect the two circuits in parallel. It's use is for high current and low voltage motors or generators.

Evidence? So any generator, in excitation-generation conversion action has an efficiency greater than 100 and well over that. And mechanical force is the condition of moving excited magnetic poles in a magnetised stator. The constant that the electromagnetic generator is a converter of mechanical energy into electrical energy is a pure lie of official physics. The Lorentz force is very controversial evidence, especially in the phenomenon of the Anapole moment of electromagnetic induction. You see how easy it is to doubt in you revered postulates in which you believe but do not understand their mechanism.
Lenz's rule is also pure rubbish in modern interpretation, see the original source.
