LaFonte Group can turn off permanent magnet without work

[mscoffman]

@Penno,

Butch Lafont seems a very reasonable fellow, So maybe just e-mail and ask.
I say it is ferrite because you can't create Lenz eddy loss currents in the
appropriate ferrite. In the arms of device, you would not need those iron
layers with ferrite, because each particle is electrically insulated from
it's neighbors. That means no lenz loss current in any flux direction.

You can use this BLF concept to create more efficient motors, it is just that
they would probably require electronics controls and some of their total
flux path would have to be devoted to running themselves. So economics
would be a problem. A motor can't buffer energy when it's lightly loaded
to play it out when it's heavily loaded (much) without additional externals.
Energy saved would have to be in input cycles skipped. - Having the drive
coils turned completely off during various AC input cycles would work.

Very large generators would be a problem, because once they are synchronized
to the utility grid, they switch between running as motor or generators
based on how much thermal energy is gated into their turbines. So utilities
"overdrive" them - overrun their rotors - to send out power. This is called an
AC synchronous alternator. With this the BLF solution one would halve their
output and have them run without any input.

Howard Johnson's 90 degree principle is not far from a working solution.  Although it proved to be of marginal output, it was quite close to overcoming the problem.  One may build a rudimentary arrangement similar to Johnson's and see for one's self, quite readily, that there are many field changes with astonishingly little friction in the system.

It is my guess that any system with magnets in such close proximity, that can be made to turn with such little resistance, is ripe for copious energy production with a little creativity in coil shape and placement. 

Johnson was, perhaps, so focused on getting his PM system to turn of itself, that he may have underappreciated the fact that it turned so freely at all....


This same condition exists in many of his would be succesors. 


Why seek to 'turn magnets off'.  The stronger the better.

Hi all,

Well bugger me -

I walk into the Fitting & Machining section of the college I teach at and begin to describe the magnet switch I wish to replicate, hoping to have a student or someone bore the 19mm hole needed to house the neo magnet - the store man looks at me and says, we have those here already.

He proceeds to show me a MAGNET BASE as used in the trade to lock down work pieces or hold precision gauges while marking or while using the lathes.

He was even kind enough to give me an old one that had the post broken off.

Sure enough, turn the knob, and the base grips with a very strong force. return the knob to off and it releases with ease.

I must admit, it takes a bit of effort to turn the knob the 90 degress from off to on, though it easily springs back to the off position. This appears more force than Butch is using to turn his switch.

I am keen to pull this unit apart and see just how it is working.

Anyway, I will get the shaft I have drilled and continue with a replica of Butch's unit, cause I want to try the switch to power a magnet only motor.

Kind Regards, Penno

I've heard of these devices.

This could be poor mass production machining. Try taking it to
bits, clean up the mating surfaces with emery cloth, and put it
back together with light machine oil.

Hi guys,

I haven't had a chance to pull the MAGNETBASE apart, but I can tell you that what I was going to try was on my rotor, place just washers or blocks of metal and drive Butch's switcher with a cam. No having enought time to check this out tonight, I simply placed this BASE next to my rotor with 19x28mm neo and with a very small movement of the dial, I was able to manually get the rotor to turn.

What caught my eye with Butch's design was, as soon as you moved the slotted ring just a few degress, the magnet would attract. That is what I was hoping to setup.

Anyway, this gives me hope, and I will post a pic soon.

Kind Regards, Penno
