Abstract:
The present invention relates to a spoke-type permanent magnet rotor (1) used in brushless direct current electric motors (16), forming the rotating part inside a stator (17) that forms the stationary part thereof and having an air gap (18) between the inner surface of the stator (17) and itself, comprising a cylindrical core (2) produced from ferro-magnetic laminations or ferromagnetic powder metal, a shaft (3) fixed to the core (2) and forming the rotational axis of the rotor (1), 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) arranged between the pole segments (6), more than one magnet (8) tangentially magnetized, placed in the magnet slots (7) and extending outwards in the radial direction, and two end rings (9) produced from non-magnetic materials such as aluminum and plastic and fixed on the front and rear planar surfaces of the core (2) by the injection molding method.
