[/quote]Maybe that will change it all. What about possible gear ratio? Or does that not have anything to do with it as long I have used torque as measurements for all parts?

Lets say the counter torque of 322Nm for 66,67% of the measurement period should be scaled up due to gear ratio. I will check this right away. Because the rotor use 30 degrees to rotate the stator 180 degrees. That is a gear ratio of 6:1.

322 x 6 = 1932

1932Nm countertorque spread on 66.67% of the period does in average 1288Nm.....

2 seconds (or days)....I will check this out.

Dooms day for my little idea:

I calculated the energy spent to do the operations.

Within 45 degrees the rotor provides about 2kJ
Within 180 degrees the stators takes about 2kJ

So I have learned a lesson: Do not base ideas on torque only. It is the torque pr. distance that matters - energy!

I'm mad, but not surprised. I will recover soon

We learn from our failures. You have the right attitude though. Keep it up!

Hi Low-Q and all you other guys dedicated into the intriguing task of harnessing the forces of the permanent magnet,
as a newborn member on this inspiring site I will first of all declare my deep devotion into the mystery of magnets and the
possible ways to create torque.

Now I really hope I'm not sounding patronizing, but after having studied several different approaches to create torque
in magnetic motors, they all seem to fail due to a common error in understanding the interaction of magnetic fields.

I am fairly convinced that no matter how the configuration is done, nothing will ever be gained as long as both poles
of the magnet are exposing their fields into the electromagnetic three dimesional surrounding.

As far as I understand, the crucial key is how to hide part of the magnetic field geometry trough effective shielding,
thereby gaining the necessary direction of force vector.

Otherwise it all evens out, no matter how intricate the interaction of magnetic fields is incorporated in a model.

Today the possibilities to shape, shield, hide or rearrange the geometry of the magnetic field is greatly enhanced
by the combination of new materials like pyrolytic graphite in combination with multilayers of soft iron shields and bismuth.

So my advice is to incorporate a discriminative shielding in a direction that enhances the desired torque vector.

This would certainly work just as well on a modified version of your 180 degree radially swapped motor,
as on for example a simple Perendev-type.

I am personally now initiating a series of tests in the art of shielding and reshaping magnetic field geometry, and will
keep you informed of my progress if anybody is interested.

Let,s solve the magnet riddle, it's the cleanest energy there is, and additionally it will free humanity from the grip of authority.
