A spoke permanent magnet rotor

The spoke-type permanent magnet rotor (1) forming the rotating part of an electric motor (13) inside a stator (14) and having an air gap (15) between the inner surface of the stator (14) and itself, comprising a cylindrical ferromagnetic core (2), a shaft (3) forming the rotational axis thereof, a hub (5) disposed at the center of the core (2) and having a shaft hole (4) that bears the shaft (3), more than one pole segment (6) disposed all around the hub (5), more than one magnet slot (7) disposed between the pole segments (6), more than one magnet (8) placed in the magnet slots (7) and extending outwards in the radial direction, two end rings (9) produced from non-magnetic materials and fixed on the front and rear planar surfaces of the core (2) by the injection molding method, and more than one magnet holding protrusion (10) extending from each pole segment (6) over the magnet slots (7) between the magnet (8) and the air gap (15), characterized in that more than one slot orifice (11) situated between the magnet holding protrusions (10) and narrowing from the magnet slot (7) towards the air gap (15) in the radial direction, and more than one bar (12) produced by injecting non-magnetic material into the slot orifices (11), extending along the core (2) in the axial direction between the end rings (9) and surrounding the core (2) between the magnet slots (7) and the air gap (15).
