It's 1:00 am and I may be so sleepy I'm wrong on this, but I believe I have a major break through with a Pseudo Solid Stator design. Look at my drawing on my free web site until Sky can upload it to my paying web page.
The rotor is pulled to the turned magnet (second one down the role in drawing), then that magnet is turned inline with the first, the cycle keeps repeating till it gets to the end and stops (rotary version just keeps going around in same direction) Then is move back to start the cycle over. This can be tested at home with radio shack magnets and a piece of glass as a divider. Interesting thing, the magnets rotate to line up with the steel rotor with more force than it takes to rotate them back sideways after the rotor is slid back to the start. This elimates any rotor banging.

Hi Butch
I am really impressed with your work and going to test my mini version on LPSS. I am using the parts from small D.C motor as the rotor. I cut four rotors from the armature of the D.C motor. Does the arm have to be non-magnetic it looks like you are using metal on yours. Will post pics once I get things together.
On your LPSS you are rotating your magnetics 90 degrees and then back again. Would this not use up energy for each flip. And how would one do this easy. Looks hard to build.

Wayne,
I think the LPSS is much harder to build
and it is vague, if it will work.
Go first with the LPSR and yes, you can use magnetic arms.
Post some pics, when you have any results.
Thanks.
Regards, Stefan.
Hi Stefan & Butch,
Have a look at my crude flux contour and you will see why the LPSS will not work. Rotor 1 will be strongly pulled back to it's mate rotor 2.? :(
Greg
Greg,
but waht about the lower part of the rotor ?
There is still the force to go on !
ALso at the bumping of the rotors the kinetic energy is
huge and is transferred to the other rotor, so it should be able
to overcome the sticky spot.
Maybe some iron shielding plates at the top stator magnets
will help.
Regards, Stefan.
Hi Stefan,
The spot torque force pulling the lower rotor CCW is very much lower than the torque force puling rotor 1 CW (back to rotor 2). Integerated over distance the two torques will equal.
The bottom line is there is no continual magnetic gradient here. Plot the flux density gradients around the loop (it is they who generate the torque the rotors feel) and you will see it is conservative.
Greg
Yes think you are right the LPSS makes no sense to me. How each one flips then flips back and has a greater force.Maybe Butch has a simple test or demo of this. The LPSR should work 360 but the banging arms won't be good. But who cares if 360 works and works.
