Simple to make Hilden-Brand style motor

[lancaIV]

Hello KatorO1,
during the first demonstration ( January 2008) with my presence  it was used the conventional net frequency : 50Hz !
But to controle the RPM the current  has to be managed by a frequency generator,
this machine RPM - as built-  goes to the 18000 rounds without  controller !

Hi,

Your zip file needs password for opening it...  why I wonder

Gyula

Well... in past weeks, after learning electrical motor theory I started to suspect that these graphs look exactly like they look. Too bad that theoretical knowledge lagged a bit behind with this and we did not spot the dangers sooner. But please do not dismantle the unit, it still may prove useful in testing coils etc.

The problem is now very sharply if focus and thats a good thing. "Classical" coils will get us nowhere. We need something with lots of turns but very sharp current rise. Impossible? Maybe not.
Also there may be some other, more clever way to change core reluctance.
It will take totally out of the box thinking.

PP Problems:

In static mode the parallel path model has a magnet strength gain of nearly four.

Yet several factors work to negate this in actual practice.

Primarily, the worst offender is that the flux will only switch, with the four times advantage, when the bar is fully aligned with the main bars.

I have prepared a simple chart from actual numbers to illustrate this fact... chart one. The gauss numbers are actually unreferenced milli volt numbers but are used to indicate the trend.

That is, the smallest distance is 1/8th of an inch that the bar has covered the main bars and the gauss is very weak at "45". The bars are in each case 1 inch CR steel so when the two bars are fully aligned, meshed, TDC, what ever term you wish to apply... then the Gauss has reached its maximum at the distance covered of ! inch.

In chart 2 we see the Kg's versus distance covered. In this case, on approach the Kg's are zero but the maximum pulling force to align the bar occurs just as the bar has covered the main bars by 1/8th of an inch. When the bar reaches full alignment the pulling force is zero. I am speaking of a rotary machine here, not the reciprocating model previously mentioned. So all same as any motor, when the poles are fully aligned, then there is no further rotational force left to operate said machine, understood?

But here we see the Achilles heal of Parallel Path machines. The maximum pulling force occurs just as the poles start to align but this is the period of minimum flux strength! And when the flux strength reaches maximum, at full alignment, then the 90 degree vector driving the machine in rotation has reached zero.

Maximum flux strength (our four times gain) = zero rotational drive.

It is not a good OU thread without a bit of mystery

Olá LancaIV,

If I understand the Imris patents you referred to and also Jorge Ferreira's patent, the principle is to use resonant LC tank circuits for motor, generator or electromagnet coils and use the reactive current of the L or C components for doing the work, is this correct? 

Would like to ask if you can answer, that in the Ferreira patent when the 6mA current consumption was measured, what mechanical load was used for the rotor?  This question is broader of course: what COP has been achived in practice, for a particular setup?

Obrigado,
Gyula
