Hmmm...  I think Magmov may be purposely hiding the configuration..

On the previous demo's they show the basic design I did..  And the only video of it actually spinning is an animation.. And when watching the animation, I can not fathom how it spins like the animation shows.  Nor can I reproduce it by hand.

Then on some crappy sales site- they post this configuration in the pics..

And again- the new images are highly confusing..  One image makes the arrangement look like a 4 stripe candy cane.
The next flat drawing hurts my brain..

...  It seems like attraction has more force than repulsion in this design. 

That may be true, but I don't think attraction fulfills the concept.  Seems
to me the principal is like a prybar wedge.  That's where you would get
your torque.  With repulsion you have the magnet clearance almost
touching and by moving the large magnet, the little magnets on the drum
have no other way to move than to turn the drum.

You might try a test with some kind of brake on the drum shaft and see
if you can force it to rotate by sliding the magnet fairly easily.  I think
that's where you will see a gain in thrust.  The linear rails will have to
be fairly stout though, if they bow out any and change the clearance,
it will be a no go.

Hello
hope not disturbing here !

notice that the mags path is not complete at the ends alternating, so not a sticky point.

Honestly I am not convinced.  I hooked up a nema 17 stepper to the shaft and can not even get the rotor to spin with that small resistance.  They are showing a row of 8mm magnets power 3X 70 AMP Generators under load for 3000 watts..  Kinda unbelievable.  Either I am WAY  off in my design, or they are frauds.  Or both. lol

I must say tho- I am interested in the effect of attraction mode..  We get double linear motion in opposing directions by turning the shaft about 1/3 of a revolution.  It would be real cool to induce a coil with the action I show in this video.

Yeah.. There are big differences in that video and Magmov's.  In both design and operation.  In that video, he is using it like a blunt-force repulsion motor.  But in Magmov's video, slowing it down suggests the rotation speed of the rotor does not meld with the travel speed of the stator magnets.  It appears to hit some type of harmonic which causes the rotor to make several revolutions per stroke.

I donno..  Even if it did work, it would need to be timed right, and I see no indication of any timer in Magmov's material.
Also notice, not 1 video exists showing the actual Magmov motor running except an animation.  Even their conference demo, they demonstrated by hand-moving a magnet. (which I did also)..

From all that I see, I am about to call it bunk.. BUT I am intrigued by the double opposing actuator the design makes.  We can easily build a generator that has a rotating center coil being induced by 2 opposing magnets travelling in opposing directions..
