Rotary electric machine

A method for arranging a synchronous reluctance electric machine, comprising:

• fabricating an annular rotor, including arranging a plurality of ferretic elements on an outer surface of a non-ferretic annular ring, including a plurality of first ferretic elements and a plurality of second ferretic elements, wherein the first ferretic elements are arranged in alternating manner with the second ferretic elements;
• fabricating an annular stator, including:
• arranging a plurality of electro-magnetic elements between a first flange and a second flange, wherein each of the first and second flanges is an annular ring that is fabricated from a non-magnetic material, and wherein each of the electro-magnetic elements includes an electro-magnetic coil, a core, and radially-oriented, inwardly-projecting ferromagnetic elements, and
• arranging a guide element on an inner portion between the first flange and the second flange;
• and
• arranging the annular rotor on the guide element of the annular stator, wherein the annular rotor is rotatable on the guide element on the inner portion of the annular stator.

A thrust generating system for a turbojet engine, comprising:

• a rotary electric machine having a plurality of radially-oriented fan blades mounted on an inner surface of a rotor;
• wherein the plurality of radially-oriented fan blades are joined at an axial center of the rotor;
• and
• wherein the rotary electric machine includes:
• the rotor disposed within an outer stator and arranged to rotate therein on a guide element;
• wherein the rotor is an annular device having a plurality of ferritic elements arranged on an outer surface thereof;
• wherein the stator is an annular device having a plurality of electro-magnetic elements arranged on an inner portion thereof between a first flange and a second flange;
• wherein each of the first and second flanges is an annular ring that is fabricated from a non-magnetic material and has a plurality of radially-oriented, inwardly-projecting ferromagnetic elements;
• wherein the plurality of radially-oriented, inwardly-projecting ferromagnetic elements are magnetically coupled to corresponding ones of the electro-magnetic elements;
• wherein the plurality of radially-oriented, inwardly-projecting ferromagnetic elements are arranged to exert a magnetic force on the plurality of ferritic elements when the plurality of electro-magnetic elements are electrically activated;
• and
• wherein the guide element for the rotor is disposed between the first flange and the second flange of the stator.
