Motor Generators

[bistander]

Any electromagnetic generator depends on the power of the load, or rather its magnetic system depends on it. Therefore, all generators are calculated based on the power of the core's ability to accommodate the field from the phase with the load and excitation. Magnetomotive force is an interesting parameter that design engineers use in their calculations. If you do not know how it is expressed in calculations, you can say that you are an empty talker.

Holcomb may have had difficulties with scaling, but it is quite possible to make a simple model for yourself with an output power of no more than 1 kW. I only recommend that everyone do this quietly and without publicity.

The "working rotating field" is established (produced) by the rotor's field from the the field coil using external excitation and it is present even without a load on the armature in the typical alternator. There is voltage on the armature terminals at no-load. It is generating this voltage from the rotating magnetic field. How can you say that depends on the load?

Sure, the design of the alternator depends on the intended load, but your statements are wrong. The rotating magnetic field in the typical alternator is present even without the load, open circuit.

Your statement "like a synchronous generator, depends largely on the connected load to create a working rotating field" is false.

Sure, but it won't do what you claim. You do it. Or hire it done. Prove it to us. Like Solarlab. Disappeared. Failure. Like Holcomb. Disappeared. Failure.

Yes, I am correct. Certainly the load current in the armature will have an effect on the field, called armature reaction, but it doesn't "depend(s) largely on the connected load to create a working rotating field", as you said, born out by the fact that the rotating magnetic field is present in the total absence of load current.

It is immediately obvious that you do not understand the subject at all or are deliberately misleading.

The excitation current forms a magnetic flux sufficient to induce an EMF, but the electromagnetic moment of the anchor reaction in idle mode is equal only to the mechanical costs of rotation. Only when the load is connected is a working magnetic field formed, which consists of the excitation magnetic field and the magnetic field of the phase currents under load; for the resulting magnetic system of the generator, this is the full flux. It is this flux that forms the electromagnetic moment of the generator; for the rotor to rotate, an appropriate mechanical force of rotation is required. We exchange the physical effort for the electromagnet control system and get the same effect without physical rotation.

Let's call the excitation magnetic flux differently - it is the control magnetic flux, and the magnetic flux of the phase currents is the working field. Ideally, these fields are equal, but in reality, especially for amateurs, the field from the phase currents is either less or more than the excitation field. If you do not know the specifics, you can not even start designing. So if we correctly organize the excitation work - control of the magnetic flux that controls the generation process, we get a stationary rotor with rotating magnetic poles.

Okay Rakarskiy,
You've thrown in a term with which I was unfamiliar and I assumed it was just an artifact of language differences. "a working magnetic field" as you call it can infer a magnetic field interacting with a moving charge, in which case there is, obviously, armature current in the dynamo.

But by the same token,

appropriate mechanical force of rotation is required

you admit that mechanical power is necessary for conversion to electrical power via the

electromagnetic moment

. That is the truth which I insist negates

exchange the physical effort for the electromagnet control system and get the same effect without physical rotation.

The "same effect" will not be realized. The apparatus becomes a transformer, not a generator. Either way, OU or free energy is not possible.

The mechanical force required to rotate the rotor by breaking the magnetic connection between the rotor and the stator is a condition, not an energy for the transformation. These two excitation fields and the phase winding have sources, one in the rotor and the other in the stator. As long as there is no source in the stator, there is no braking, only idle braking.

If we move the magnetic field in the rotor by switching the excitation electromagnets, like the anchor of a DC motor, we get the same effect as a mechanical rotor. We get generation. If we perform switching by a pulse method, breaking the system of work of permanent magnets, you get a transformation - mutual induction.

You are in a stupor because you do not know how a transformer works. How interturn mutual induction works. This is the key point for the problem of implementing a magnetic rotor with a rotating field without rotating the anchor core.
