ABSTRACT:
A rotary electrical machine has at least one stator and a rotor. The stator includes at least one armature winding received in at least one pair of slots. The rotor includes flux switching arrangement, which is adapted for selectively establishing closed magnetic circuits which pass around the turns of the armature winding. The arrangement for switching the flux comprises at least one permanent magnet adapted to establish a magnetic flux which is looped on itself in one circumferential direction of the rotor, together with at least one excitation winding for establishing an adjustable magnetic flux locally in a circumferential direction opposite to the direction of the flux produced by the magnets.
