KMG motor generator concept
« on: January 21, 2023, 11:46:55 AM »
Long time no see :)
Here is my new, fresh idea.
I've called it: kEhYo's Motor-Generator in short KMG
I welcome anybody to interpret the drawing.
A clue to start with is that all the magnets of the rotor are the same polarity pole facing out
and the magnets behind the motor coils are in opposition to the rotor's magnetic poles.
Generator coils are connected in opposition as one coil in series.
Enjoy!

Hello!

I was studying your gap generator motor videos last night.  The driving coils / magnets looks exactly like your gap motor.  They pulse to neutralize the repelling magnets as the rotor is on approach. Then when they turn off the magnets can repel the rotor and also create a large back-spike to collect in the process.

The 6 pairs of sideways coils (12 total) are generation coils. I am not sure exactly the dynamics of the pickup part, but I have seen videos of similar configurations that cause a rotor-speedup effect when 2 sideways pickup coils are mounted on 1 core.

But I will take a guess at the generation coils...   Since the connection line between coils both go over the blue spool rim, I assume they are wound opposite directions . Which makes them polarize opposite from the polarity of the  of the T-core and the same polarity as the rotor magnets. I would guess the generator purpose is to achieve a reduction in lenz if you collect at top dead center or past center because the coils would be counteracting the polarity that the cores want to polarize to from the rotor influence.

I may be off a bit- but thats my guess..

Anyway I am glad you are here posting.  I dig your work!

Good one, floodrod.
I might do some coil shorting on generator coils too if the Lenz delay/mitigation will not work as planned.
Yes. In a gist, it is GAP Power + Partnered Output Coils + Aviso Coil Shorting hybrid.

Nice!  please do continue to keep this thread updated..

After seeing your videos last night I started experimenting with a magnet on the core of my magnet motor.  Even though I am flipping polarities totally, (and my rotor alternates polarity) the magnet on the core totally neutralizes current in 1 direction and starts pulsing current in only 1 direction..

It seems flipping the magnet either makes it pulse the attraction or repulsion side.  One way goes a lot quicker, but takes more amps.  The other way takes less amps and not as quick.  But either way the magnet faces increases efficiency!

Motor with no magnet on the core-  In= 5V @ .03 Amp=  778 RPM /2
Motor with Magnet on the core first polarity- IN= 5V @ .023 Amps = 967 RPM  /2
Motor with Magnet on the core other polarity- IN= 5V @ .033 Amps = 1607 RPM  /2

My setup is going through a choke so the results may differ with no choke, but I will need to change the driver coil if I remove the choke. 
I will be testing configurations and gathering data..

Thanks again!

Scope shots below is current and voltage pulses with magnet on the core.  2 different shots depending which way I flip the magnet.

(Yellow is current- blue is voltage)

For anyone, who wants to replicate with me here is a vector drawing file in scale 1:1 on A3 size format.
The wire I am using is 0,8mm. Coil formers are standard medical tape packages. 55m diameter 26mm inner diameteter.
All coils wound bifilar Tesla style for increased capacitance. The cores are composed of iron powder/iron oxide/resin mix.

A small update.
New, wooden base 40x30x4cm (beech cutting board).
New CNC milled rotor and a ceramic bearing.

The new rotor is ready. It weighs 2 kg with magnets!
I've noticed that it is hard to true the center of the bearing on the bolt as there is some wiggle.
I am not in the rush, I'll will keep you posted.
I will be using Arduino and a NOKIA LCD to display parameters in real time.
Lots of work but I BELIEVE it will be worth it in the end ;)
