Re-Inventing The Wheel-Part1-Clemente_Figuera-THE INFINITE ENERGY MACHINE

[bajac]

This design includes a battery not shown in the design. Once again, this circuit needs a "Violent Field Collapse" to trigger the oscillation!

TinselKoala,
I had never seen a motor like that one. It looks very interesting.
Could you do a close up into the rotor? I cannot figure out the stator.
It looks to me that the rotor turns are short circuited and the stator is very closed to the rotor. Then, it should definitely have good torque. Because short circuit is a fault condition, I am guessing that the rotor turns shold be connected in series with some kind of resistor embedded in the rotor as a way to bring the current within acceptable margings. The rotor current is still expected to be high. Is that right?

Thanks,
Bajac

Yesterday, I wanted to post a link but the website was down. Does anyone know what happen?
Anyway, I came a cross an ingenious coil design known as the "serpentine" coil. It is found in this webpage:

You do not have to worry about soldering coils together or if a coil has more or less turns because it is a single large coil.
I was thinking about making one big round coil and then use a custom tool to push the edges inward to get the serpentine shape.
Thanks,

For my 1908 version, I think the last major piece of the puzzle is in place now.



PS. Notice this is not the Tesla rotating field!

TinselKoala,

I'm sorry, I don't have that motor here with me. These images are all I have available at the moment.
The "stator" is just the big slab of ceramic magnet material, and the green sheet shows how it is magnetized in sectors with the poles facing outward. I think the poles alternate N and S around the stator; the viewing film just shows the direction not the polarity of the field lines.

It looks to me that the rotor turns are short circuited and the stator is very closed to the rotor. Then, it should definitely have good torque. Because short circuit is a fault condition, I am guessing that the rotor turns shold be connected in series with some kind of resistor embedded in the rotor as a way to bring the current within acceptable margings. The rotor current is still expected to be high. Is that right?

No, as far as I can tell there is no resistor in the rotor, the "windings" are just all connected together pairwise at the inner and outer edges, and the brushes run along the flat central portion of the "winding" layer. Yes, the thing is very flat, the rotor disk is very close to the stator magnet when the case is assembled. No, the rotor current is normal for a brushed DC motor of similar torque with an iron armature and heavy cogging. The "stall" current is high of course, just as with any brushed DC motor.
I can't quite figure out how it works exactly either, nor do I know what to call the design. All I know is that it is a car radiator fan motor sold by AC/Delco and I bought four or five of them at the surplus counter at Princess Auto in Canada, five dollars each.
Ah... there is a little ceramic capacitor mounted outside the case, between the brush terminals. This is normal, to reduce sparking and extend brush life, in many DC motors.

Thanks,
Bajac

You're welcome, I wish I had the motors here to play with. I used them on a big Bonetti machine and the lack of resistance, non-powered, is important to show the "motoring" effect of the charged-up Bonetti machine, something that is underappreciated and not well reported.

Thank you for the explanation, TinselKoala.


As I said before, I did not know this motor. I will Google it to see if I can find more information. It really looks different from any other motor I have seen. I am kind of puzzle with the application. Normally, fans do not have motors with brushes because they are required to be simple, reliable, and maintenance free. Using a brush motor for a fan application is something odd.
