Patent ID: 7701104

Claim:
A rotating electrical machine that has a rotor with a body made of magnetic materials, a stator surrounding the rotor; the stator has at least one armature coil, and the rotor has closed notches in the body and devices to selectively establish closed magnetic circuits passing around the armature coil of the stator; these devices include: permanent excitation magnets able to generate magnetic fluxes; excitation coils housed in the notches of the rotor to define coiled poles; said coils are able to be excited and generate magnetic flux components to counter the fluxes generated by at least some of the magnets to create defluxing; wherein the number Na of magnets and the number Nb of excitation coils and the arrangement of the coils and magnets in relation to each other form a plurality (Nme) of identical elementary patterns (me), wherein each elementary pattern is defined as a set of magnets and coils associated with a specific order and distributed over all or part of a contour of the rotor and wherein the plurality of identical elementary patterns are used to control the basic power of the rotating electric machine, wherein Na is equal to or greater than 1, Nb is equal to or greater than 1, Nine is equal to or greater than 1, and the pair Na, Nb is different than 1.1, and wherein each elementary pattern (me) comprises at least one reluctance pole.
