Energy Generation by moving Mag Field through Static Steel Core & Copper Coils

[Ufopolitics]

Hello to All,


Ok, the Groschopp Universal Motor runs beautifully, very smooth, no spark gaps...I still need to take it to 3600 RPMs and take Armature readings of V&A


These type of motors after you turn them off completely...they keep spinning freely for a long while...since they do not have magnets...there is zero magnetic friction....feels great!!


But  there "was" an issue...this motor have 24 elements in the commutator, my Rotary Switch commutator have only 16 elements...


So I have to get all this into a CAD...in order to find a possible sequence...without affecting the Magnetic Field overall behavior.


And yes, I found it...while the only change would be minimal in Field performance...here is the diagram for connections plus the angles of field propagation.


When Brushes are in between two segments (division of two elements at center of brush, as shown on Diagram) of a non connected element. the Field will reduce from 24 total Coils to 20 Coils active...meaning 10 Coils North and 10 Coils South...until brushes make full contact with commutator element, then Field will go back to 24 Coils active, 12 Coils per pole.




Edit 2: Again, this fluctuation of the field (from 12 to 10 coils per pole) only takes place eight times in a full turn, while Field running in full (all 12 coils per pole) through the other 16 full contacts...since there are only eight elements not connected, and spread around the 24 elements circumference.


Please note that all light blue Motor Commutator elements are not connected, so I am jumping one every two elements connected...with a total of eight [8] Coils which are not connected to switch, however, they are all still connected in  series between them.


So, this sequence will take place only in the transition from element to element...and not affecting the whole main  field overall performance...I hope.


Edit 1: Where I believe I would be able to notice this is on the Scope signal...maybe a bit of scattering, not a straight smooth curve...we will see.

Hi Ufo,

You know a lot more about this stuff than I do, but isn't this setup apt to cause a lot of sparking at the brushes? Maybe AC caps across the switch's commutator segments would help?

Just a thought.

Hello Cadman,


It shouldn't...let me explain.


This is a typical Symmetric Motor , a Lap wound where coils are all in series.
They run very smoothly at "idle" (no load)...no sparks...current (Amperage) maintains itself regulated at a constant level...and when accelerated it even comes down a bit.
However, the minute you add a mechanical load, everything changes...sparks galore and currents increase to max values.


But, on this design, I will not have any mechanical load at the rotor...it is just rotating a massless field through the metals (steel & copper)...the rotor would be static.
And as long as the prime mover (small motor) keeps spinning the field, the rotor coils will just keep "warm"...

It is the same, exact function, as when the motor is running at idle...no mechanical load.

When we add a load at output stators, they will magnetize stronger, but rotor is static, so Lenz have no where to go...where to act.

And the rotating, Exciting field may demand a bit of higher power (by showing a drop at loaded output power) to compensate for the stronger magnetization of the stators...that is all.

Same exact behavior as a loaded generator, where the gas engine needs to step up torque and speed , because it drops as heavier loads are added to output...
AVR will detect this drop at output, and increase magnetization at Exciter Coils...

And here we will not need a higher torque, just increase a bit of speed to small motor and power to Exciter...which will eventually be done automatically by the stators exciting coils (not on this test yet) when speed of rotating field is increased.

I will be adding a small AC Cap, at the input, between both brushes...but for another test I am planning as well.

However, these are all assumptions, until I test it for real...setup will answer all our doubts...I maybe completely wrong.

It did arce and sparked a lot prior, when I was collapsing the coils in every single degree of rotation...


We will see now...


Thanks and warm Regards friend.

Hello,




Here is an update image...


Done with the rotary contacts wiring and small universal tool motor commutator wiring ...now match and connect.
Still lot of work ahead...but, getting closer...


Had to clean up a huge mess on bench previously...to now create a second mess...


Btw, I got one of the LCR Meters yesterday (orange one, on right hand of screen)




Cheers

Hello...and Happy Eastern to All!!


I have done some quick tests with the small RYOBI Hand Tool...and it came out wonderful.
Of course, this is a small motor so have to play with smaller voltages.


But the main issue here that I want to share, is how I have set the brushes on the rotary switch...yesterday, I was testing with just two brushes...and there was a lot of sparking, a lot of BEMF returning back to Input PSU...


So I decided to close the Field Range by adding four brushes (this brush housing on switch, was designed for 4 brushes) but they have to be in a way that is NOT as Motors have it.


Normally a four brush motor will have an arrangement of /+/-/+/- / and that way the field gets split into Four Fields at the Rotor.


However, I did it in order to keep just one field, but close its angle at the Poles, by setting brushes like: /+/+/-/-/ , therefore, the coils within the two plus (+) and two minus (-) will not be energized, not generating a field, but just conducting power...and so, Field Spectrum is way much cleaner.


Magnetic Field will not have any "scrambling" which happens with just two brushes...and it is due to coils at the contacts (+/-) will be intersecting with BOTH main poles...I will make next week a CAD to show what I mean, however, on my previous image here that have an armature, wound with lap windings, you can see that I colored these next to input plus and minus in a different color (magenta) than all the red-blue coils defining the North-South Poles.


I will upload again that image here...for easier access.
I will also upload a picture here of this way to arrange the four brushes at rotary switch...


SHORT TEST VIDEO


Now, this video above is NOT Published on my Channel, (I do not want my subscribers to go like WTH is that??...lol, since I always give an explanation previously) so, it is UNLISTED, and I made it just for this Forum.

P.D: This video is not trying to demonstrate any Overunity at all...it was only intended to show a couple of things.


1- We can increase Output Power by just increasing Field rotational speed, without affecting -at all- Input parameters (V&A).
2- Also to share the huge difference it did to my previous tests by changing to four brushes, the way I have described prior...
