Abstract:
A rotary electrical machine, comprising a stator (100) having at least one armature winding (140) located in slots defining stator poles, and a rotor (200, 210, 220, 230, 240) mounted for rotation inside the stator, the rotor having at its outer periphery magnetic poles comprising, firstly, North-South magnets (210N-210S, 220N-220S, 230N-230S, 240N-240S), and secondly, magnetic reluctance pieces (215-215â€², 225-225â€², 235-235â€², 2430-2440), wherein the North-South magnets (210N-210S, 220N-220S, 230N-230S, 240N-240S) of two consecutive poles n, n+1 are grouped side by side, and in that the magnetic reluctance pieces (215-215â€², 225-225â€², 245-235â€², 2430-2440) of two consecutive poles n+1, n+2 are also side by side.
