Simple to make Hilden-Brand style motor

[Nali2001]

Hi Wiz,
Yes that is a standard test. The valve will support a magnet bigger then the remaining core cross sectionof the valve. Without leaking to the tortor. It is all more or less tuned. The core easily supports the statdad 20x20x10 neo used.
But you are right about the lower rpm is better.

Nali !

Your core is cut to half where the coil is so seems to me that original path could have too high mag.resistance.
This is easily to test - see if, with added magnets (on both sides) and no current, rotor spins freely. and doesn't wan't to stick to stators.

If rotor wants to stick to stators - mag field doesn't close through coil(when off) completely. I think it should close completely (not genesis like) because those motors of yours are small and magnet field, if not closed properly, easily will "touch" rotor even not overlaped - especially
if one magnet pair is N-S and another is S-N....and rotor is allso high permeability.
This could be reason why RPMs droped !

Allso I would go with weaker magnets - 2/3 value of where satturation starts (0.8- 1T) - cause magnet fields must travel with coil field

besides I think that RPMs doesn't drop so much (few rpms) but current drops substantially - You have only two drivers
and current droped to half. with more drivers (four) curent drop will drop not half but probably to 1/3th

all other experiments with high rpm (beyond 1000) are not good I think for first FE results...maybe later on...

all the best !

Well I will see what I can do.
Need to piece some things back together since these videos are a year old or something and the motor circuit and stuff is not complete anymore at the moment. Will look into it.

@Nali !!!

wonderfull videos... much to leran from them

I'm watching your videos over and over again and after some time I tought that there is one crucial thing that should be tried:
(except for checking flux leakage and complete flux closing - my previous replay to You)

- lower down RPM to 800 RPMs , but not with mechanical friction on shaft, but with lowering down input voltage (input energy).
this is principle of valve - (1.) low input energy pumping (2.) strong magnetic flux of PM (this is must procedure). And not (1.) 144W of input doing (2.) friction on mechanicall break (3.)...
- then add magnets

What happens ?

Please Can You do video of this ?!! 

I expect RPM should rise significantly (not just few RPMs but huge difference) - due to RPMs input lowers further  

then would be nice to place some generator on shaft....

You can easily build and use a prony brake with a digital scale to measure the shaft output.

@Ergo

Many thanks for this info.
This should be easy to make and further more it will tell if added genearator for retrofeed is working efficiently enough.
I was looking for this missing part.

@All

do You think allso that Nali in his experiments is overdrivig the coils at least a bit too much, so amplification of force from magnets is not observeable  ?

hELLO ALL,

This was Jack W Hildenbrand patent,,,,,, Just simpn up up by billding a set of steel  shale around.   http://www.genesis-corp.co.jp/type2.html


How do you think there will be under getting a patrtent on the USA.
