Simple to make Hilden-Brand style motor

[wizkycho]

My last post in this matter.

I never meant to distract you from doing work.
What you are doing is fine but I find it strange if your not curious to know whether you have found overunity or not.
Many times people tend to fool themselves because they never bothered finding the right answer. It's just so painful.
Everything I told you is the pure truth. If you decide not to believe me then your mind is clouded and you will utterly fail.
You sound very unwilling to face reality by performing a simple test. But this could shatter your own imaginary perception.

My Claims.
1) When running your motor you'll notice that your dealing with milliseconds and this takes lot more power than static mode.
2) The available flux is not strengthen by the added magnet versus the power needed to run the valve.
3) The claims above and the fact that you still have to face the Lentz law when trying a self-runner will finally enlighten you.

Lentz will slow down the rotation but, you see, then the Torque (FORCE) becomes Stronger and acts Longer ( yes !!!) (of course with magnets  ) - its exactly what we need - Stronger and Longer acting Forces when under Load,

I'm in process of building 4 cores rotor so 50(Hz)/4 times = 12.5 RPS(econd) or 750 RPM (cool - like an older powerfull diesel engine) is a optimal rotational speed for my motor so I do not have to use exotical hard to get materials for high exotic freqs - and I'm not in RPM's (for now) I'm in Torque - Force - Energy extraction. If RPMs are wanted , just put mech gearbox, and still losses in input cores stays the same - very very low, just like in common trafo that uses that freq.

I allso have a very good idea based on extraction of BEMF. The thing is when BEMF spike is shorted (used-accumulated and not just wasted)  it actually acts on mag-trans in a same way original pulse does. means reroutes field back to rotor again. This way Input is cut to half (picture) and scince BEMF is restored that would bring input to 25% of what this used to need. On the other hand Output since using
Magnetic field Transistor drivers is 3-4 times Stronger. That makes this motor COP 9 -12.
If resonance is implemented afterwards COP rises 50 - 100     

FM type pulsing is not tested here and actall mod. frequency is dependant on coil inductivity and properties of core. electronics to do that
is simply acomplished and not making additional losses cause mod freq is still low freq. around 250Hz to 10kHz worth to try.

So let's spin it up

Sounds good! Yes the vid is good proof that there is something there. You can get an idea of the strength of the spring by how quickly the rotor is returned to its rest position. The rotor is no light
weight... it weighs 4.4 Kg. With no magnets it has barely enough strength to hold its self in, yet
with the magnet stack installed it accelerates the 4.4 Kg rotor upwards, against the spring, to trip
a daggy slide switch and strike the stop with a fair whack... I like it.

I like your low speed choice too. My words exactly.  I think everyone can see my design philosophy
here? The coil should about match the strength of the magnets... the flux path needs to be kept
short, the speed needs to be low. Geometry and proportion are the critical factors.

Good luck with yours!

Wow, some impressive work going on here. Keep up the good spirits.

I have read about your plans on how to run the motor. I used to help Hilden-Brand in the past and I have learned that the coils is of high inductance and it could affect how to run the motor at it's best.
I have used this page successfully myself in my present FBDISSM design. It tells you the charge time at a certain voltage.

All you have to do is measure the resistance and inductance of your assembled motor.
Here a list of simple but good LCR meters. I bought mine a year ago and have never been regretful. I use it in daily basis.

Please enjoy the attached example. I just entered some Hilden numbers to get a useful calculation.
A Hilden-brand valve usually need 2 amps to fully redirect the neodymium power if properly built.
If your coil is being 250mH and 2.5ohms it will take you 10ms to reach 2 amps at 53V.
Im facing the same thing in my FBDISSM.

Hi there Wiz,
Well I can only applaud anyone actually building this stuff. So keep us updated!

About your "bemf" capture thing. Keep in mind that if you chop up the single square wave in multiple small parts you are in a sense raising the frequency multiple times. Which means you needs lots more volts to actually get the same switching going on. I recommend you use very low impedance coils. And one thing I also found that capturing the 'Bemf' (inductive collapse /fly back really) in these valves does not go without punishment (especially a solid state/non motor valve ). The capture process actually makes the valves so that thy trend to resist a flux drop in between the pulses. Which means their field does not go 'off' all that good. And in my case it lowered the rpm and upped the amps draw. Although I might add that dumping that inductive collapse into a cap instead of straight to a load does make the capture much more viable.

And how do you intend to use resonance in these motors? The are not ac systems.
I found these things to be tricky to get right, I only went to 36v in. Pulse initiated by the opto and afterwards controlled by the pwm but I had to advance the timing almost a whole stator pole width to reach good speeds. So indeed keep the rpm low. The rise time is in my opinion one of the major speed controlling factors. One other advice I can give is use variable input power since thing thing at 36v will blast so many amps at start that it immediately kills a irfp250 fet. So start it at 12v or so and when it spins you can up the volts in.

Regards,
Steven.

Good to see you on the list Honk!  I think most of us are readers of "the other" list and have seen
how badly treated you were. None of that here as you can see...LOL

Good links!  the hyper physics link in particular, that will be very useful. Well the price is reasonable
on the meters... and as my DMM has lost its resistance accuracy (abuse) ... time for an LCR, thanks alot...I guess you can hear how I said that? lol

What is your FBDISSM?  you got my curiosity going....
