Abstract
A rotary electric machine arranged as a brushless electric ring motor is described and includes a rotor that is disposed within a stator and arranged to rotate on a guide element. The rotor has a plurality of ferritic elements arranged on an outer surface, and the stator is an annular device having a plurality of electro-magnetic elements arranged on an inner portion between first and second flanges. The first and second flanges both include an annular ring that is fabricated from a non-magnetic material and has a plurality of ferromagnetic elements. The ferromagnetic elements are magnetically coupled to corresponding ones of the electro-magnetic elements to exert magnetic force on the ferritic elements of the rotor when the electro-magnetic elements are activated. The rotary electric machine may operate as a first thrust generating system that is upstream of a second thrust generating system for a turbojet engine.
