    • A multi-pole electric machine rotor assembly includes a rotor forging including a rotor body having poles 13 with pole faces and a winding module including a plurality of field windings positioned adjacent the pole faces and winding insulators disposed between each successive pair of the field windings, respectively. A winding block, disposed in engagement with the winding module, is shaped to be shifted to a final position relative to the winding module when the rotor assembly rotates at about its rated speed to thereby compress the winding module. Either the winding block or the winding module can be displaced by centrifugal forces during rotation. In the final position, the winding block is locked by friction in a position to maintain compression in the winding module. The winding block serves to provide a pre-stress in the field windings to keep the field windings tight over the design range of spin speeds, thereby controlling winding position and reducing alternating radial movement.
    • 一种多极电机转子组件,包括转子锻造,其包括具有带极面的极13的转子体和包括位于极面附近的多个励磁绕组的绕组模块和设置在每个相继的励磁绕组对之间的绕组绝缘子, 分别。 当转子组件以大约其额定速度旋转以便压缩卷绕模块时,与卷绕模块配合设置的卷绕块被成形为相对于卷绕模块移动到最终位置。 在旋转过程中,绕组或绕组模块都可以通过离心力移位。 在最终位置,通过摩擦将缠绕块锁定在维持卷绕模块中的压缩位置。 绕组块用于在励磁绕组中提供预应力,以将励磁绕组紧紧地保持在旋转速度的设计范围内,从而控制绕组位置并减少交替的径向移动。
