Abstract
A rotary electrical machine, comprising a stator (100) having at least one armature winding (140) mounted in slots which define stator poles, and a rotor (200) mounted for rotation inside the stator, the rotor having at its outer periphery magnetic poles comprising, firstly, North-South magnets (210N-210S), and secondly, magnetic reluctance pieces (215-215′), wherein the North-South magnets of two consecutive n, n+1 poles are grouped side by side, and in that the magnetic reluctance pieces of two consecutive n+1, n+2 poles are also side by side.
