PM_Square: (PM)^2 : Permanent Magnetic Motor project
A Stefan Hartmann's Idea
created on 10/26/97 - JLN Labs - last update on 10/27/97
I have added a steel plates on magnetic bars at the outside of the apparatus. This steel plates contributes to build a constant magnetic flux density between the magnetic bars. In spite of this change ( a constant magnetic field density ), the resulting force always exists, this seems to confirm that a rotary version is able to work in a rotary closed loop. A rotary PM^2 can be designed by mounting two ring magnets shielded by two steel plates and the two magnetic sliders rotating between them (see below).
This is the rotaty version proposal by JL Naudin, based on the Stefan Hartmann linear version.
This version is under development and not yet fully tested.
