Electric generator with solid state magnetic rotor.


An invention that is interesting in its simplicity.
Park Jae-soon's solid-state power generator 
A device for generating electricity using a brushed DC source that rotates with a field pole generator, the device for generating the DC source  US8629588B2 (Simply put, a solid state oscillator with a mechanical switching device)
The present invention relates to a device for generating power by means of a brushed DC source that rotates with an excitation pole generator, the device comprising: an excitation pole generator having a plurality of iron cores around which a coil or wire is wound; a winding wire used for generating power, the winding wire being formed to be wound around the excitation pole generator; a commutator that is arranged at one end of the generator.

Type of installation from the patent
The invention is quite simple, from a design point of view. If in a collector generator the armature with collector blades in fixed brushes rotates. In the proposed variant, the armature is stationary, and is placed in the stator, with a slot winding of the generator winding. A small drive motor rotates the brushes around the collector, thus switching the armature electromagnets and creating a rotating effect of the armature field.


Last year, a similar principle was also proposed by a searcher from Russia. Unfortunately, he could not move further from the achieved point.

Type of experimental setup

Video of the experimental setup. The rotor and stator are stationary, only the brushes rotate around the collector-lamella assembly, which is stationary with the rotor. My sketches, suggestions, which quite overlap with the project discussed in the article.

Collector and brush assembly
The rotor should form a two pole or more efficiently a four pole design  Two phase alternator winding. To begin with, a rotor with power drive to rotating brushes should be made. In the grooves lay one coil of the phase and determine the best EMF. Then calculate the phase and make the stacking of its winding. 
SUMMARY: All that is present in this invention is the same technology of Clemente Figueras. This principle was probably realised by the Spanish engineer Clemente Figuera. Why I think so, you can read in the material: GENERATORS CLEMENTE FIGUERA 1902


A researcher under the nickname UFOpolitic has conducted mongo experiments to create such a setup. Follow the link to the OverUnity.com forum to learn more: https://overunity.com/19085/energy-generation-by-moving-mag-field-through-static-steel-core-copper-coils/

It is enough to look at the picture and the date, the question of the priority of the idea shifts more and more to the depths of the past years. Patent Shoji Haneda, is based on the model of the simplest electromagnetic generator with a core, when you look at the details you can immediately see the whole algorithm of work to induce EMF in the winding of the generator. The author took the design of the simplest electromagnetic generator (position A) and replaced the rotating magnetic rotor in it with a static magnetic rotor in which the electromagnets are switched on the base of the collector brush assembly (position B).

The induction of EMF in the generator winding occurs only on the conductor section that is induced inside the magnetic circuit. This is fully consistent with the transformer EMF formula. Magnetic force lines of magnetic flux do not cut (cross) the conductor. 

 E = (Φ = ∆B*S)f /√2at the moment (2π/√2=4,44)
Е = 4,44Φ

The slide shows all phases of one EMF induction period during the rotation of the magnetic flux in the rotor. Does it matter the physical rotation or rotation of the magnetic DC field in the electromagnet switching system. One thing to take into account is that the cross-section of the magnetic core in the total addition of the electromagnets' cores should correspond to (or better slightly exceed) the cross-section of the stator magnetic core on which the generator winding is placed.
Why I say that, you can read it: A transformer with a mystery - "how"?   

In my opinion UFOpolitic made a mistake when orienting the maximum EMF to the placement of the phase windings in the slots and the coverage of the pole radiation of the rotor to the stator. 

This is what this solution looks like, which you will find in any common school textbook. It echoes the winding of the field winding in a conventional single-phase synchronous generator. But the power winding is stacked in the grooves so that its tab is placed neatly in the space between the poles. Usually 4-5 grooves are used for laying one pole and the same number of grooves on the other side. I have marked the locations of the phase wires (1/2 phase) in the figure with rectangles and red arrows.  With a little bit of imagination I placed the UFOpolitic rotor in a stator with 48 slots. I got a five-phase design. YouTube channel with UFOpolitic experiments.

There are 4*2=8 slots per phase. Each phase can be brought out separately or combined into a complex star. Everything should be checked by experiment. Another thing to check is to put a transformer between the rectifier and the phase.
The peculiarity of rotational modelling should be the constant component of magnetic induction at the actual poles of the rotor during its movement.

 UFOpolitic has set up a forum where this design and others like it will be discussed. overunitymachines.com

The peculiarity of rotation modelling, should be a constant component of magnetic induction at the actual poles of the rotor at its movement relative to the stator!

(Supplement 2024, January, 3)
A video of an experiment, with a similar static generator design, where the static rotor solenoids are switched via an external collector-brush commutator has recently become available to me.

The picture below is a photo of the installation, voltmeter readings on the multimeter, battery charge before start-up #1 (10.57 V), and in the process  #2 (11.57V). On the right is a simplified diagram of switching the design to a common battery.  Let me explain what we see. We see a rise in voltage on the battery, which indicates that it is charging during operation. The main point is that the battery cannot charge and deliver current to the load at the same time. So to operate the excitation system (commutator motor and rotor solenoid excitation), the current comes from the stator phases, which are connected in parallel, through diode bridges. Thus, there is a clear excess of power in the system, which provides energy self-propulsion of the system, excitation of the rotor electromagnets, rotation of the commutator and battery charging.
When analysing the winding of the stator of the plant, it can be seen that the authors have made the winding on the four active magnetic poles of the rotor. In essence, everything that I proposed in the analysis of the work of Robert Holcomb's electric generator. [Holcomb Energy System - FREE ENERGY]. It makes no difference how you activate the switching of the electromagnets according to a given algorithm, so that a certain part of the electromagnets is always switched on at the active pole. For example, we have two electromagnets, at some point switched on at the maximum point. Between the active magnets, one electromagnet is switched off (in grey), just that zone in which the focus of magnetic flux for maximum EMF is formed. Then one is switched off at the end of the chain, the other is switched on in front of the chain, forming the movement of the magnetic pole, one remains switched on. Figure below. 
With two feed brushes, the four active poles of a solid state rotor can be freely commutated. An example is shown in the figure below, with two switching positions:
The figure shows one coil group of a four pole solid state rotor. You should have a minimum of three / four groups (12 solenoids /16 solenoids). If you have one group switched off, the other groups must be switched on to the power supply. When switching, one group of magnets is always switched on.  
To understand what kind of EMF should be generated just study the material where I have chewed up all the points on the example of simple calculations:  EMF and current force
I was told that the author of the video does not agree with my view of the essence of the processes. Honey, no one is stopping you from stating and publishing the essence of your assembly and proving me wrong. I have stated what I came to in my research much earlier than your replication of Park Jae-Soon's patent US8629588B2 2014-01-14 (priority of claims 2009-07-09 KR1020090062765A Korea). No matter how you switch the coils, the algorithm can't be different since in similar devices (wire in the stator slot) the magnetic flux force lines don't cross/cut.  There is another interesting commutation, but it belongs to a slightly different design.
So that there is no doubt as to whether your Overunity installation works, the wiring diagram for the installation should be assembled according to the diagram below:
We have a DC circuit with loads: a mechanical commutator for the rotor solenoids, a DC motor to move the commutator brushes, an additional third-party load, a ballast battery, and an AC circuit from the alternator stator phases that are shorted into the DC circuit via diode rectifier bridges. 
Before starting the system, switch on only switch S1 beforehand, fix the amperage (A) on the ammeter in the circuit of the battery minus terminal. The voltage in the circuit, it should sag slightly. This will be the discharge current of the battery (the ammeter will show the direction of the discharge current). Next switch on the switch S2, connect as a source of EMF from the generator phases. Check the voltage in the circuit, and the current in the two ammeters. If the current direction on the battery ammeter has changed direction, it indicates that the battery is being charged and in this case the battery has become a load. Next, switch on switch S3 additionally and check the system capabilities.  
If the battery continues to discharge when the phases are connected to the system circuit, the system does not have enough power generated by the generator stator phases, provided that the battery is charged or the current on the battery ammeter is zero, the system operates in self-propulsion mode..
