This must work! Altering magnetic field without cost. OU or not?

[Low-Q]

I have a question for you regarding the torque.
What would the torque be if re-modeled to a 60cm diameter rotor? Total outer diameter may be 70-80cm.
I'd like to compare this to my own design and besides that I think 7.6meters is to big for most people to care about.
If presented in a smaller and easier to comprehend design it might catch replicators interest some more.
And it won't be as costly as a nuclear plant.....

I scaled it down to 60cm in diameter rotor, and 10cm deep, and the torque on the rotor alone is then about 95Nm. That is with 40 grade neos. If I have right about the countertorque I got about 30Nm in average for one revolution. If I have luck, I have all 95Nm. I tried to remove all the Statormagnets 2, and checked the force acting on the crankshaft. I marked all the Statormagnets 1 (I had deleted Statormagnets 2 to see what forces affecting Statormagnets 1 separately) and found that the total counterforce is only 5000N for the big model - compared to the 750 000Nm torque from the rotor. That is only 7 per thousand spent on altering the magnetconfiguration.

So either there is 30Nm or 95Nm to spare for pure torque in a 60cm rotor 10 cm deep....

However, I do not guarantee that my calculations are correct. There might be something i have overlooked, but I have only trusted the simulations and my math skills (Which I hope is a bit over the average ).

Hi Low Q
Can your engine work if magnets1 would be in the form of pistons
and magnets 2 in the form of cylinders ?
I still dont understand how you overcome point where attractive and
repulsive forces are balanced.
Would engine works if  the stator contains only four magnetic 1+2 arrays
devided 90 degree apart from each other ?

Well, all the statormagnet is connected via a crankshaft. If you try to separate two magnets like they do in the stator, they will each take force to slide them apart and away from the sticky spot. But there is allways a magnet set that is going together somewhere else - doing the very oposite. This force is equal, so the net force to separate two sets of magnets are therfor zero. If the rotor was made of a non magnetic material, you could use you little finger to rotate the rotor in a 7.6meter model - so to speak.

There is no point in using one magnet as piston and one as cylinder, but that will ofcourse work in the same way.

However, you do not need both Statormagnes 1 and 2 in the stator - only 1 or 2. So you could use magnets as pistons, and used a nonmagnetic material as a fixed cylinder. Now it really looks like a radial engine, and it is now easy to guide the magnets in the right directon. The main thing is however to let the most densed magnetmass (Where the magnets is at its closest to eachother) be in place where is makes the most unbalanced position in proportion to the rotor.

I have made another alternative that is easier to manufacture. I have used the original design as template, but removed the Statormagnets 2 and replaced the rotor with a pure magnet aligned 45 degrees.

I will put this design out here as son as I'm finished with it.

Thank you for that fast reply of yours.

It's pretty similar compared to my own design but I have stickyspots to overcome.
My design is 80cm wide (statormagnets and mounting steel included) and 10cm deep (15cm with mounting).
The stall torque is varying between 160-200Nm in my calculations, somewhat less in real life due to some design circumstances.
Taking the sticky spot in aspect I might hit 80-90Nm. I have yet to carefully measure the total torque accessible.

I scaled it down to 60cm in diameter rotor, and 10cm deep, and the torque on the rotor alone is then about 95Nm. That is with 40 grade neos.

Hi,

What do you mean by RH, LH and Perpendicular RH. I lost you there - well most everything...

LOL!


Yeah, something like that.  Alternating current merely reverses polarity.  The real fun happens at induction.....at which point, more options are readily available.  I've seen a handful of setups which seek to utilize the "90 degree principle" to supply motive force.  Missing forest for trees.....

To me, the impressive thing about the "90 degree principle" is that one can get all those field transitions, or 'field changes' for next to nothing.


Magnets make great levers.


Levers with long, 'magic arms' that go right through all sorts of stuff......
