摘要： A laminated rotor for an induction motor has a plurality of ferro-magnetic laminations mounted axially on a rotor shaft. Each of the plurality of laminations has a central aperture in the shape of a polygon with sides of equal length. The laminations are alternatingly rotated 180° from one another so that the straight sides of the polygon shaped apertures are misaligned. As a circular rotor shaft is press fit into a stack of laminations, the point of maximum interference occurs at the midpoints of the sides of the polygon (i.e., at the smallest radius of the central apertures of the laminations). Because the laminates are alternatingly rotated, the laminate material at the points of maximum interference yields relatively easily into the vertices (i.e., the greatest radius of the central aperture) of the polygonal central aperture of the next lamination as the shaft is inserted into the stack of laminations. Because of this yielding process, the amount of force required to insert the shaft is reduced, and a tighter fit is achieved.
摘要翻译：用于感应电动机的层压转子具有轴向安装在转子轴上的多个铁磁性叠片。多个叠片中的每一个具有呈多边形形状的具有相等长度的边的中心孔。叠片交替地彼此旋转180°，使得多边形孔的直边不对准。由于圆形转子轴被压配合成叠片，所以最大干涉点出现在多边形侧面的中点（即在叠片的中心孔的最小半径处）。由于层叠体交替旋转，所以当最大干涉点处的层压材料插入到堆叠中时，相对容易地进入下一叠层的多边形中心孔的顶点（即，中心孔的最大半径）的叠片。由于这种屈服过程，减少了插入轴所需的力的量，并且实现了更紧密的配合。

摘要： A protector assembly and method for protecting motor windings from an overload condition. The assembly comprises a thermally responsive protector, a skirt, and a sleeve. The protector comprises a housing, an end cap, at least one terminal, and a thermally responsive member. The end cap covers an open end of the housing. The terminal extends through the end cap. The thermally responsive member is within the housing and adapted to be electrically coupled to the motor winding via the terminal. The protector is adapted to be positioned in heat-transfer relation wit the motor winding in a manner such that the thermally responsive member is responsive to an overload condition of the motor winding. The skirt and sleeve are of dielectric materials. The skirt is positioned on the protector in a manner such that the skirt surrounds the end cap and the terminal. The skirt is between the end cap and the sleeve. The skirt and sleeve are adapted to provide a dielectric barrier between the protector and the motor winding when the protector is positioned in heat-transfer relation with the motor winding.
