Nice to see interest in this design.
Well to me the major advantage of the Flynn motor over the Genesis and Hildenbrand valve is that the fields of the magnets do not have to be forced out the core loop...

Flynn said that the coils should be controlled with Pwm and not voltage.

Thanks for that Post Steven, I can never remember how it works but that explanation makes it clear.

Little sidenote,

depending on the form of the available material or transformer. pivoting can be made in different planes. When having something like typical MOT trans as source material it is possible to make pivoting both in XY and XZ planes, depending on the height of the magnets, XY with tall ones and XZ with flat ones.

With square cross section core only XY makes sense, like Italians did.

Interesting is that in XZ plane variant flux path is never entirely broken but in static test I could not find big difference between the two, kick was only a little bit better.

In any case pivoting works much better than piston-like movement (just varying airgap), "power zone" reaches about twice as far with pivoting. With piston zone is too narrow to convert into rotary action.

Hello, I'm Francesco Ranchella, I'm glad you are seeing my work on the Parallel Path. The video "Comparison asynchronous motor and MK12" I'm translating in English and Spanish, so you can better understand what I say.
If you have any questions that I have available, sorry my bad English.

Kekko Greetings!

Hello Francesco and welcome!
Great work, yeas please translate your video(s) it would help us a lot.
Well I have one 'basic' question at this point:
'Have you reached overunity?'

You use pretty big IGBT's!

Thanks for sharing.
Steven

Instead of cutting laminations you could also get some C-cores and machine them a bit and bridge the magnets in between.

Hello, I'm Francesco Ranchella

Hi, glad you joined us

I have a question:

Have you any idea what is force amplification factor in your motor?
I mean what is the torque with magnets versus torque without magnets.
It still works without magnets, yes?

This is VERY important, if you have not tested it maybe you could try it in simulator, as I understand you have proper simulation of your motor.

Thanks in advance!

- perfect PP system is symmetrical, this calls for twin rotors

yssuraxu,

A positive delight to see your test results, excellent work!

Incidentally, had you seen this twin rotor?

Hi and thanks

No, I havent seen this, twin rotor was just logical conclusion after seeing power gain in my static twin-gap experiments.
But seems that guy on the video did not get very good results and also moved to multi-pole motor.
Possible that twin-rotor like this (or pivoting system) has too many mechanical losses compared to actuator power.
But there are million other things that may degrade performance so who knows.

But most important in these motors is amplification factor, most other things can be tweaked but amplification factor is bound to design principles. So for me a lot of questions will be answered if Francesco would tell amplification factor in his motor.

Hi all,

I am working on a solid steel (cold rolled) reciprocating model, which is nearing completion. But drilled the three holes for the ball joints too big which upset me no end. Quit for the day (Saturday) and will resume Monday by making bushings to fix my mistake...

I am going this route (reciprocating) because of my age, my fascination with reciprocating steam engines when young, which allows me to identify with the model posted in that first link.

Hi Ron,

oh je, I can understand you were upset.

Yes, this is the reason I named this maschine "magnetic steam-engine" or in german "magnetische Dampfmaschine"

Have some coffe and relax

Kator

Hallo Kator,

New day, just did up a teak wood base for a pottery vase for my sister that turned out not too badly, lol, yes good advice, will have a cup of tea and get on with some stepped bolts for my magnetische Dampfmaschine,
I like it!!!

Bis dann

Ron

Hi, by coincidence I was working with wood also, oiled oak dining table

Otherwise I started work with "Ã¼ber-windung". Inductance is under control, will start with investigating backspike boosting possibilities. Ordinary "solenoid" winding is thing of the past

Will post again when full analysis is complete. Sometime in weekend I guess.
