    • A rotor is provided. The rotor includes a rotor iron core including slots formed around an outer circumferential portion thereof; magnet pieces which are inserted into the slots, respectively, such that a magnetic orientation of the magnet pieces are inverted every predetermined number of the slots; and two end plates, one end plate disposed on each end side in an axial direction of the rotor iron core, the two end plates covering the slots in the axial direction. The rotor iron core also includes cutout portions, which are located at an interval between adjacent ones of the slots, each of the cutout portions extending in the axial direction of the rotor iron core. One of the two end plates includes injection openings, each of which corresponds to a respective one of the slots, and communicating grooves each of which is formed so as to communicate with one of the cutout portions.
    • 提供转子。 转子包括转子铁芯,其包括围绕其外圆周部分形成的槽; 分别插入到槽中的磁体片,使得磁体片的磁性取向每预定数量的槽反转; 和两个端板,一个端板设置在转子铁芯的轴向方向上的每一端侧,两个端板在轴向方向上覆盖槽。 转子铁芯还包括切口部分,其位于相邻的槽之间的间隔处,每个切口部分在转子铁芯的轴向方向上延伸。 两个端板中的一个包括注射开口,每个注射开口对应于相应的一个槽,并且每个连通槽形成为与其中一个切口部分连通。
