A method for making and magnetizing an un-magnetized mechanically keyed permanent magnet rotor that can be magnetized in a magnetization fixture, without regard to the angular position of the rotor in the magnetizing fixture, and nevertheless result in a permanent magnetic field angularly synchronized to said keyed rotor comprises the steps of providing an annular permanent magnet or annular permanent magnet rotor body; a mechanically keyed rotor shaft; means for aligning and assembling the un-magnetized permanent magnet or permanent magnet rotor body and the mechanically keyed rotor shaft during assembly to form an assembled rotor; and magnetization thereof.

1. A process for making a magnetically keyed rotor, comprising the steps of: a) Providing an un-magnetized annular permanent magnet of anisotropic material composition and corresponding molecular polarity grain, with said member having an axis and bore concentric with said axis, and said grain orthogonal to any plane containing said axis, and comprising the step of placing or integrating a coupling means within said plane and dividing a section of said grain into equal sections of opposite polarities, so as to form a grain-keyed magnet, andb) Providing a mechanically keyed shaft, with said member having an axis, and comprising the step of adding or integrating an alignment means into said member, and synchronized with said member, so as to form an aligned shaft, andc) Assembling said aligned shaft and said grain-keyed magnet by passing said shaft slidably through said hole in said magnet, allowing shaft and magnet axes to coincide, and allowing said alignment means in said shaft to align along said coupling means in said magnet, and applying a mechanical permanent attachment means between said shaft and said magnet, so as to form a mechanically keyed rotor assembly having an axis, and magnetizing said rotor assembly radially, flux orthogonal to said rotor axis, without regard to any rotational or angular reference key on any magnetization fixture, so as to form said permanent magnetic field, whereby said magnetization of said assembly in said random-angle fashion nevertheless angularly synchronizes said permanent magnetic field to said mechanically keyed shaft and forming a magnetically keyed rotor. 2. A process for making a magnetically keyed rotor, comprising the steps of: a) Providing a plurality of un-magnetized annular permanent magnet of anisotropic material composition and corresponding molecular polarity grain, with said members each having an axis and bore concentric with said axis, and said grain orthogonal to any plane containing said axis, and comprising the step of placing or integrating a coupling means within said plane and dividing a section of said grain into equal sections of opposite polarities, so as to form a plurality of grain-keyed magnets, andb) Providing a mechanically keyed shaft, with said shaft having an axis, and comprising the step of adding or integrating a plurality of modular alignment means into said shaft, with said plurality of alignment means occupied in a plane containing said axis, and synchronized with said shaft, so as to form an aligned shaft, andc) Assembling said keyed shaft and said grain-keyed magnet by passing said shaft slidably through said holes in said magnets, allowing shaft and magnet axes to coincide, and allowing said plurality of modular alignment means to be added to the resulting assembly and to align along said plurality of coupling means in said plurality of magnets, and applying a mechanical permanent attachment means between said shaft and said plurality of magnets, so as to form a mechanically keyed rotor assembly having an axis, andd) Magnetizing said rotor assembly radially, flux orthogonal to said rotor axis, without regard to any rotational or angular reference key on any magnetization fixture, so as to form said permanent magnetic field, whereby said magnetization of said assembly in said random-angle fashion nevertheless angularly synchronizes said permanent magnetic field to said mechanically keyed shaft and forming a magnetically keyed rotor.
