Magnetic Torque Multiplier

[wizkycho]

Hi Everyone,

For anyone interested, i have already started to make some CAD drawings for a simple version of this thing that we can all build. The present version uses 1/4" x 1/8" square Neo magnets for the disks which are 1/4" thick Plexiglas 3.75" in diameter. it basically just has a bunch of notches cut in it to glue the magnets in. So to make the rotor disk, you simply need two of these disks.

I will finish up the CAD drawing I made and post it here so everyone can see how to do it. This thing is painfully cheap and simple to test so I believe we should be able to quickly prove or debunk it. it would be awesome if Clanzer could knock this up with his CNC machine. that would be quick and simple to see if this works.

If anyone else here is interested, please let me know what size magnets you have and I can make a scaled drawing to fit the magnets you have. According to the patent, you will need 56 of the same sized magnets. the 1/4" x 1/8" square magnets I was looking at using sell for $22 total if you order 100 on KJ Magnetics.

God Bless,

Please O please post THA drawing ... and make us free.

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.

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.

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

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.

Hi Wattsup,

I partially agree with your analysis in that it would take a pretty high input RPM to produce an output RPM compatible with most standard generators. However, I believe that this magnetic worm gear configuration is much different than its mechanical analog. But rather than explain it myself. I'll just quote the patent itself. Check out these excerpts:

"The ideal magnetic torque multiplier provides a sizable and useful torque step-up at the large wheel based on the magnitude of the magnetic force between the opposite permanent magnet sets on each of the two revolving components. An added advantage for this manner of magnetic force transfer using individual, opposite magnetic segments is that no friction is imposed between the two components as in the case of the mechanical contacting worm and worm wheel counterparts. The helical magnetic rotor can run at high speed without surface contact, with a reduced-from-normal rated input torque due to alternating attraction and repulsion of the driven magnetic wheel acting on the rotor magnet segments. It is most desirable to use large and powerful rare earth/cobalt permanent magnets for both opposite sets of magnetic components to achieve a large torque output differential between the driver and driven shafts. "

"The primary wheel torque is produced by the uniform displacement of the adjacent wheel magnet segments as they are influenced by the uniform lateral displacement of each magnet segment of the rotor's single pitch helical path."

There are more paragraphs like this but the inventor is basically saying that this device not only acts like a normal worm gear and worm wheel setup but actually increases the output torque beyond the simple mechanical  output because the magnetic fields are doing the pushing and pulling rather than the motor that is turning the input rotor.

You can also see the effect from the drawing at the bottom of page 3 of the patent. You can see that turning the larger wheel cannot impart a mechanical torque on the driving wheel because the attraction and repulsion forces cancel eachother out in the plane of the input rotor. So if this one proposition is correct, then it can be quite clear that this is stepping up the mechanical power input, and not just the torque ratio. The inventor seems to believe this because he then says the following:

"The principal object of the invention is to provide the highest torque output for the large, driven wheel from the lowest possible torque input for the small helical rotor, as a useful power step-up means for many electrical generating applications.

Another object of the invention is to provide a step-up power source which can be produced at competitive costs, requires no combustible fuel and is non-polluting while running silently, and requires a minimum of parts replacement and maintenance.

It is a further object of the invention is to provide a natural energy source which has an extremely long operating life, with a maximum of operating effectiveness and component resistance to degradation. "

Ok, now, I could be misinterpreting this here but it seems to me that the inventor is strongly suggesting that the device is not only increasing the mechanical output power from the input, but is doing so by tapping into some kind of "natural energy source" which can't be anything other than the magnets.

So if this were just a simple mechanical setup, I would concur that there isn't anything special going on, but as soon as you start to bring magnetic fields into the picture, particularly dynamic magnetic fields, then you are dealing with an open system. I believe that this device is worth a shot and if it does what the inventor is strongly implying, then it may be a simple and effective way to use a small energy input combined with the energy provided through the magnetic field interactions to generate extra power.

Also, to address your comments about the speed issue. It is very easy to get low torque, high-speed electric motors that could reach 100,000 RPMs with no problem. But this won't be necessary. If the device works as claimed and there is little to no back-torque induced on the driving disk, one could easily use a gearbox with the same gear-ratio as the setup to run the input rotor at high speed and then step it back down through the device to the same speed at a higher torque.

Normally this wouldn't make any sense from the mechanical perspective UNLESS the magnetic fields are providing input energy as the patent holder claims.

Any drawing about your understanding how it works?

Like that
Then I will become very sceptic about this idea
Airgap changes ... and when Nr.1 and Nr.8 meets togerher what then
