    • The present invention relates to a spoke-type permanent magnet rotor (1) used in brushless direct current electric motors (12), forming the rotating part inside the stator (13) that forms the stationary part thereof and having an air gap (14) between the inner surface of the stator (13) and itself, comprising a cylindrical core (2) produced from ferromagnetic 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) disposed 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.
    • 本发明涉及一种在无刷直流电动机(12)中使用的轮辐式永磁体转子(1),其在形成静止部分并具有气隙(14)的定子(13)内形成旋转部分, 在定子(13)的内表面与其自身之间包括由铁磁性叠片或铁磁粉末金属制成的圆柱形芯(2),固定到芯(2)并形成转子的旋转轴的轴(3) 1),设置在芯部(2)的中心并具有承载轴(3)的轴孔(4)的轮毂(5),布置在轮毂(5)周围的多于一个极段(6) ,设置在磁极段(6)之间的多于一个的磁体槽(7),放置在磁体槽(7)中并沿径向向外延伸的多于一个切向磁化的磁体(8),以及两个端环(9 )由非磁性材料(如铝和塑料)制成并固定在公司的前后平面上 (2)通过注塑成型法。
