Perm. magnet only core with iron shell, motor coil

[Floor]

The drawing and descriptions I am posting are not a very clear explanation at this time.  So I will make a clearer explanation here:

The design is of motion producing device, linear or rotary.

A permanent magnet is embedded within in an electromagnet. 
This electromagnet  / permanent magnet combination
is embedded within a magnetizable shell ( probably made of soft iron lamination ).
There is no core inside of the coil, other than the permanent magnet.
The permanent magnet's strength and it's distance from the shell that encloses both it and the coil
allows little or no linkage of the permanent magnet's, magnetic field with the magnetizable shell.

I have named the combination of these three elements an electro permanent magnet (E P M).

When the coil of the E P M is energized so that the coils magnetic field is in alignment with the permanent magnet field,
the electromagnet will have a percentage of the permanent magnet's magnetic field added to it.

When the coil is not energized the E P M will not behave as a magnet, and there will be no magnetic attraction, to
other E P Ms or other elements of an electric motor design, except when the E P M  or  E P Ms are  energized.

Interesting 
Have you done any more than the idea and drawings, anything physical built and measured?
If yes, can you share any numbers? Thanks for contributing!

I have not built any prototypes yet.  I am still looking at variations of design.  I will be posting
these variations before I move on to building a prototype.  I'm considering a variation of one
of the linear models for a first test.  I intend all of this for the public domain.  As soon as it hits
this forum please consider it anyone's to use, share, publish or sell,  as long as so doin,
does not prevent anyone else from doing so as well.  With this exception: keep in mind that
ideas / designs that I post could have been previously patented by someone other than
myself.


Thanks for the inquiries.

This last jpeg is the architecture for the first prototype I'm building. A Linear motion version.
