Magnetic Torque Multiplier

[wattsup]

@Jdo300

I know it looks good but in no way is the inventor saying it produces more electric output then input. From the date, I would guess the main use of this invention up to today, which is not minimal, is to make magnetic drives for certain pumps and other rotating equipment that required a fully uncoupled drive, meaning the drive end cannot stop the driven end if either side jams up. If the big wheel jams, the drive end will not feel or take the hit.

It is electric motor driven item (12) in the patent.

It may be a very effecient design for such a drive, but it will not provide you with any overunity, simply because of slippage. You see, the inventor says it has no friction, but he does not say it has slippage. When you have a generator on the other end and start plugging in a lamp or two, you will realize it and then you will start on a vast system compensating endeavor.

But I am curious about an idea or a slant on this design. What if you took just the two magnet wheels, but doubled the quantity making two big wheels and two worm wheels then position them as two opposing forces on each other to turn without an electric motor. Or if you took three of these pairs and made a triangular self-turning thing. Or four of these in a square design.

What I mean is if you are doing this for the OU, I would advise against it, but if you plan to try it as a perpetual motion thingy, hmmmmmmm, maybe.

Nice drawings.

Simple Push/Push design I like more. N always -> to N and S always -> to S  ... holds and keeps like lubricant, like the best grease

And hereby my very simple push-push version of magnetic worm gear,
This is one-thread, also two-thread is possible.
To save the time I did not place magnets under better angle on the worm wheel ...
cheers,

Running such a design off of a worm gear means you will have a high ratio between worm to gear. This means, depending on that ratio, you will have to turn the straight worm anywhere from 40-100 times before the gear makes one rotation. That's why worm gears are used in very high torque applications that require 10 or 20 or 100 rpm.

Correct. And we all know that getting really high rpms is not really easy...

This means that for the gear to turn anywhere near 3600 rpm for a 60hz generator, your drive side will have to be turning anywhere from 180,000 rpm or more.

OK, you can use multiphase low rpm generators, or a pulley, gears,.. up conversion... Still, additional losses and no OU.

Also, you will need a minimal torque just to start the worm gear to turn because they are usually very hard to turn.

Indeed. Worm gears are rather inefficient, usually driven with a small power (motor). The friction between the gears can eat up most of the power delivered.... (Look at the car windshield wipers). With all the leverage, they still look very powerfull.

So even if he used a magnet driven wheel or any other form of drive, you still have to contend with the worm gear ratio and the minimal rpms required to produce any decent generator output.

Added:

I would also like to point out that this patent was filed in 1977 and issued in 1979. If this device had any promise, I would think that between then and know it would have reached the market somehow, but from considering the above limitations, I can understand why.

Interesting, eh?  No FE here. What I see is a rather complicated and more expensive mechanical setup, the main advantage is arbitrarily lower mech. friction (under strict conditions).

@khabe

Hello! Nice pictures! Yes, something like this... Still, the real source of power (or energy) or any conversion calcs remains the same as with a classical snail gear. No OU, surprisingly...

Seems none interested about Magnetic Gear I built my tiny version,
http://www.overunity.com/index.php?topic=5810.0;topicseen

I have looked this desigh http://www.infolytica.com/en/coolstuff/ex0106/ long time,
Finally decided to try - and was very disappointed - too hard cogging.

Also I have several couplings and  gears based on  eddy effects.
