The invention discloses an electric machine having features that enhance the load transfer performance of a rotor of stacked laminations. An electrical machine includes a stator having stator slots within which conductive windings are secured. The rotor is rotatably mounted adjacent the stator and includes a stack of rotor laminations. Each lamination includes circumferentially spaced apart poles, each pole including a magnet slot spaced apart from an insert slot. The laminated magnet slots cooperatively define magnet slots of the rotor. Similarly, the insert slots of the laminations cooperatively define the insert slots of the rotor. A magnet is mounted inside a magnet slot of the rotor, and a non-magnetic insert is mounted inside an insert slot of the rotor. One or more poles of each lamination include structural webs extending radially through magnets and insert slots of that pole. The plurality of poles of each rotor lamination lacks radially extending structural webs. Each rotor lamination is rotated relative to an adjacent rotor lamination such that each pole with a structural web is axially aligned with a pole without a structural web.

    本发明公开了具有增强堆叠叠片的转子的负载传递性能的特征的电机器。电机器包括具有定子槽的定子,该定子槽内固定有导电绕组。转子邻近定子被可旋转地安装并且包括转子叠片的堆。每个叠片包括周向间隔开的极,每个极均包括与插入件槽间隔开的磁体槽。这些叠片磁体槽配合地限定转子的磁体槽。类似地,叠片的插入件槽配合地限定转子的插入件槽。磁体被安装在转子的磁体槽内部,并且非磁性插入件被安装在转子的插入件槽内部。每个叠片的一个或更多个极包括径向延伸通过该极的磁体和插入件槽的结构腹板。每个转子叠片的多个极缺乏径向延伸的结构腹板。每个转子叠片相对于相邻转子叠片旋转,使得具有结构腹板的每个极与不具有结构腹板的极轴向对准。
