Simple to make Hilden-Brand style motor

[LarryC]

LOL. thats where you have me beat Larry,  I can only suffer through a document like that for about three
minutes before my attention span is used up... no, I hadn't read (or understood that part) THANKS!

Not really Ron,

This was one of the few patents (6,369,479) that I have ever printed out so I could sit down and compare side by side the table data to the graphs. It is a wealth of information about hybrid magnet characteristics and I highly recommend to anyone who wishes to understand the advantages and characteristics. It also clearly compares the EM only force to the EM plus magnet force at various current levels. Like I mentioned before, they must have spent hundreds of thousands on this research.

Now, can you help me? I did try to get the German patent info into translators, by doing a copy and paste. But from the pdf I was getting a "copy image" and then I couldn't paste into the translators.
Please let me know how to get it done.

Thanks, Larry

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.

1. If using say 5kHz it is still very low freq for FETs that in creation of this freq wan't cost any more power.(just creation here)
2. this driving freq. doesn't travel to output at all core-coil is to "slow" for that. so when switched off and fast again on (in this, small-width-off-state" out mag field can not drop back (again slow core coil). And another on state keeps output magnet field on.
Therefore magnetic field output will look like it was driven with normal pulse although I will use 50% less energy DTC 50%. that drop emidiately can be meassured at input.

This two points above is idealised components theory. In practice energy savings will be 25% with this DTC of High freq at 50%.
for 25% savings is worth to try. and not yet taking into account bemf gains.

The capture process actually makes the valves so that thy trend to resist a flux drop in between the pulses -

this is exactly what i intend to use, flux shouldn't (when high freq on) drop cause of capture process and slowness of coil-core (that allready established ON state so oposing that change).

please do read more carefully. You first write I'm wrong and then make same statement. !?! what's up ?

@i_ron
Thanks for the experiments but what really convinced me that there is at least "something" is this (static)
http://ca.youtube.com/watch?v=JRNZSu31ZZo. waht is not on video is I tried to lift a steel ball and it is impossible without magnets...
Congrats on being second after Hilden-Brand. BTW Hilden-brand proposed and made setup where magnet-valve(magnet-transistor) is in paralel with
rotors core.
every another success exp is lifting us higher
if missed this is what i'm finally building
http://www.overunity.com/index.php?topic=1319.msg132627#msg132627 (that topic is much older than this one - read it)
the principle of work is given long before hilden-brand or flyn by JLN in Magnetic Energy Pump experiment and made it Opensource. unfortunately for him Hilden-brand can legally protect only putting magnet in a core - and that is not a must to make workable device.
So anyway we are free to make these OU motors.

You asked!!! lol

Its that bl**dy PDF format that is hang up.  But as you have found out, if you go up to the top there is a selection tool, then the selected block can be recognized in word (not note pad) but it is still in a format that you can only print.... so I did. Then scanned it and ocr'ed it then it is  recognized in note pad. Copy and paste from NP into Babel fish.... after removing the hyphenation...My Epson twain
will (can be set to) recognize German, which helps. I know just enough Deutsch to know where the
beginning and end of words are...hehehe

Some words babel doesn't get but it is not hard to follow the difference in construction between
english and german and fill in mentally what is being said.

Ron

Oh, one other thing... babel only does 150 words so break up your note pad text into smaller blocks.

Good advise Larry... I will have to do that.There is so much info in the patent, it is like a snow storm
when you try and do it on screen....one suffers from snow blindness.

On the translation.... the tables and charts I can understand right from the document...
the occasional word or two that needs translated is best done in...

You should try http://translate.google.com it tends to give more grammatical intelligent than bablefish. For some reason for me all the pdf files on that patent website only display the first page.
