Hi there Wiz and nice to see some thoughts going on.
However in your simulation I do not see the fields of the coil when it is on. You show only the fields of what the magnets will do. But the field of the coils obviously also want to go somewhere. And I don't know how much tough you put into the overall dimensions of your simulation but in reality that thing will oversaturate if neo magnets are used. I always see it as 'units' the steel when the coil is on must at each side support two units of flux, one from the magnet and one from the coil. A unity in my way of thinking is as big as the cross section of the magnet so of your magnet has a cross section of 20mm you can expect a piece of steel of also 20mm cross section to more of less support the field of the magnet without saturation. In you image the cross section of the steel and magnet is the same. But you must keep in mind that the field of the coil also must be accounted for. So that means steel must have an additional 20mm cross section. So it can accommodate the magnet field and coil field.

But all besides that I have never found this type of device to work as a o.u 'transformer' In all my models it simply does not matter if you add magnets or not. There always seems to be a straight coupling of the input and output coils and largely ignore the magnets. Although it is all fun and games in simulations it is a whole different reality when put in to practice. In motor applications on the other hand it does hold big promise.

Nali2001, I don't think wizkycho is showing an idea for a transformer. Just like your concept he's showing how you can turn on or off the strength of two magnets with a little energy input by a coil. This can then be used to cause rotation much like Dr. linderman's attraction motor but in this case you use the dorment power of permanent magnets instead of the coil to make the field that momentarily attracts the rotor.

Hi Nali2001 !

  Scince You haven't posted ziped,rared fem file I made simplified stator core of your motor, but different
magnet coil arrangment (the way it should work - closer to Hildebrand and mag. trans.) and it has, If nothing, one advantage -
no cutting of stator to insert the magnet.

The metal in Center is simplified rotor spaced 0.25mm, both sides ->0.5 mm.

Satturation of ironsheet is 1.4T and I use 1T worth of flux of magnets so there is 0.3 - 0.4T room for coil flux. Magnet and Core is equaly wide 20mm - so nothing is saturated. simplified rotor is twice that 40mm so it can "conduct" complete flux from both magnet pairs.
So dimmensions are right.

About Coil flux - I haven't drawn any flux on these pics, I gave coils 1.1A -> 0.8W at the end, every flux line is drawn by FEM the program
and It by itself makes an ERROR cause it is programmed by false "conservation of energy" (and flux lines) principle - everything must be nullified in a given area so FEM actually ERASES !?! existing flux lines from coil (... and it shouldn't cause in reality magnetic flux is not behaving this way).
0.8W is energy needed to "overcome" airgaps of rotor, after that coil flux are showned. Just like in common Current tranz 0.7V to start behaving like transistor.

Broli - You drawn the right position of magnets and coils

Gylasun - No coil in center, just rotor (again, I drawn it simplified), no lenz for now - mechanicall output

To Nali2001 -
maybe your setup could work, but I think that flux wan't go all that way arround core if airgap to rotor is small (and should be smaller as it can get). Is there something written on the motor (Current, Voltage, Power) -  seems small for washing machine ?
Thanks for the idea Nali cause I'm having undescribeable tourment to find someone willing to make sheets for prototipes.
Everybody acts like everything is invented and mankind allready Knows everything - it is so so far from that point.

wizkycho, I feel with you. We live in a time where people get laughed at that want to change the world into a better place. Or get ignored if they want help on some research. We should be living in a world were research is promoted, where they throw all the equipment at you just so you can do research so humanity can keep advancing technologically. It's technology that solves problems not a credit system or the lies of a politician. The political monetary system must be destroyed and become a social technological system. No money no politics no poverty no bullshit.

broli; They will never do it as long as you have control freaks who want to own everybody, and act like a God.
