  • Publication number: 20020135452
    Abstract: 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.

  • Patent number: 6177749
    Abstract: 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.
