True DC brushless motor

This radically new coil-magnet arrangement is the result of thinking outside of the (magnetic shield) box, while still considering the old Maxwell and Lorenz equations.
It is obviously NOT a perpetuum mobile, doing electrical to mechanical power conversion like any other electric motor, with Joule and Eddy losses as well.

Here’s a very basic animation:

Because of the costly required Mu-metal and custom machining, I do not have a proof of concept unfortunately.
Even if it works it would not completely replace conventional brushed or switched BLDC motors, because of efficiency and power density limitations (part of the coil is unused and has Joule losses without contributing to the electromagnetic torque).

If you know about any other true DC BL motor, please let me know.
