Toroid-magnet-generator
« on: August 31, 2006, 12:26:18 AM »
Hi all !

I've seen this setup long time ago.
magnet is rotated in toroid core changing fields and inducing voltage at coils.
Prototype is made and gives FE.

What is stated in some paper found on internet (can't find it any more)
is that magnet field can travel through core but lenz counter field (when extracting current from coils)
remains in toroid core and doesn't creact with magnet.

even if sinusoidal current is applied to one of the coils inner magnet doesn't move a bit.

can someone find page where this is stated and what is current status of device.

Thanks

wiz

The rotating magnet generates a varying magnetic flux in each half part of the toroid core thus producing emf in the two coils.
If a current is drawn from the coils, it will produce a flux through the magnet opposing that of the magnet.
There is no reason to believe that the flux from the coils would stay in the toroid core because electromagnetism is reciprocical : if a magnet can produce linked field lines by a flux through the half-core, flux from the half-core can produce opposing field lines to the magnet.
The path consisting of the half core and the magnet is a regular path for the magnetic flux independently of its source everywhere on the path.

Many thanks for the input !

It is not said that the input should be 1000W and over to make output is overunity.
These are probably the limit power of their machine, and generator is capable
of giving overunity at say 100W input ? Am I right here ?
If I am than at lower input powers COP should be even biger than just 1.2 cause of all the losses
in input and output at 1kW power.
even COP 1.5 should be very darn good for making electrical furnace which sustains itself

I've built the torroidal generator, it's not o/u.

hi rich !

Can we see some pictures, data etc or should I (we) just believe it ?

I am building this. already ordered machining. NdFeB magnets 32MGOe from both sides
can make core go to sattuartion (if this will do something).
Can vary distance etc.
Core is laminated silicon Iron from 100W toroid trafo. Using four separated coils at first...

I built three different versions.  This is the second one with one coil filling the complete space between two magnets.  The third one had an additional coil that was the same width as the neo magnet.  The coil that was the same width put out about 75VAC but would not sustain any type of load.  The other coil was about useless.

Out of time, I'll try to post a picture later.

Here's the picture:  http://pg.photos.yahoo.com/ph/oouthere/detail?.dir=/a620re2&.dnm=a332re2.jpg&.src=ph

I used an adjustable power supply that gives the output voltage and amps.  When a 1.2 ohm load was applied across the output and measured with a typical DVM, the load power was about the same as the power increase required to run the drive motor.  The drive motor is a high effeciency brushless DC motor.

The coils were wound in typical torroidal fashion (the hard way).  The core is p/n 130 http://www.alphacoredirect.com/index.html?lang=en-us&target=d3.html that was cut in half (1" thick).  The magnets are 2" x 1/4" neo magnets.  I made the holding studs from 1/2" aluminum rod and the nuts are non-magnetic stainless steel.

Have You tried other resistances because every device has it's inner resistance
and if load is matched with that resistance than the output efficiency is maximall - higher or lower load resistance than that gives much lower efficiency. Shouldn't You try some variabile load and make grafical representation of input versus output energy...
In fact this is common mistake in measurement of possible FE devices.

Yes, I tried several but according to the patent information the load had no effect on the drive motor's power input which is absolutely incorrect.  Also, the Kromrey convertor built by John Bedini used LESS power when shorted than with no load.  These are not supposed to be a harmonically balanced systems like the Steven's device.

Rich !

Have you tried differently distanced magnets from core. seems to me that magnets are too powerfull
for the core so back flux (when load is connected) can not stay in the core
