Electrical machine comprising a stator provided with electric wiring and a rotor with a rotatable axle and permanent magnets for providing a rotating magnetic field having magnetic field lines cooperating with said electric wiring of the stator, wherein the rotatable axle has two first discs mounted at opposite extremities of the axle, which first discs have a magnetic permeability sufficient to direct the magnetic field lines from the permanent magnets to the sides of the electric wiring of the stator, and that between said two first discs and the electric wiring of the stator two second discs are provided that are arranged with sectors of relatively high magnetic permeability that are alternated with sectors having relatively low magnetic permeability. |
