    Abstract: An electric machine with a low profile retention assembly for retention of a stator core is disclosed. A first housing houses the stator core. The first housing has an axial end face with a circumferentially extending, shaped profile having recessed portions that project axially inward alternating with non-recessed portions. A portion of the stator core extends axially out from the recessed portions. A core retention spring is disposed circumferentially at the axial end face of the first housing. The core retention spring has direct contact with the portion of the stator core that extends axially out from the recessed portions of the first housing and the shaped profile of the housing. The core retention spring pushes against the portion of the stator core that extends that extends axially out from the first housing, imparting one or more of an axial load and radial load into the stator core.

    Abstract: An electric component for an electric machine includes a body having slots defined therein, and a conductive winding extending out of axial end(s) of the slot(s). The electric component may include any electric machine component having conductive windings, e.g., a stator for a generator. The electric component includes a resin dam around the conductive winding at axial end(s) of the slot(s). The resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot(s), during manufacture. The electric component also includes a (solidified) insulating resin in the slot(s) and against the resin dam(s) at the axial end(s) of the slot(s). Any number of the conductive windings and slots may include a resin dam, e.g., one, some or all. The resin dams ensure complete filling of the slots and encapsulation of the conductive windings.

    Abstract: A retention assembly for retaining a plurality of elements in a stator slot of an electric machine is provided. The retention assembly may include a stator wedge fixedly positioned in a dovetail in the stator slot to retain the plurality of elements; a top ripple spring between the plurality of elements and the stator wedge; and at least one shim positioned between the stator wedge and a load bearing surface of the dovetail. A method may include compressing the stator wedge in the stator slot from a first position thereof relative to the dovetail of the stator slot, the compressing creating a gap between the stator wedge and the dovetail. A shim may be inserted in the gap; the compressing released such that the shim retains the stator wedge in a second position that is more compressed relative to the plurality of elements in the stator slot compared to the first position.

    Abstract translation: 提供了一种用于将多个元件保持在电机的定子槽中的保持组件。 保持组件可以包括固定地定位在定子槽中的燕尾榫中的定子楔以保持多个元件; 多个元件和定子楔之间的顶部波纹弹簧; 以及定位在所述定子楔块和所述燕尾榫的承载表面之间的至少一个垫片。 一种方法可以包括从定子槽的第一位置相对于定子槽的燕尾压缩定子槽中的定子楔，压缩在定子楔和燕尾之间产生间隙。 垫片可以插入间隙中; 压缩被释放，使得垫片将定子楔块保持在相对于第一位置相对于定子槽中的多个元件更受压缩的第二位置。

    Abstract: A system for laterally moving an industrial machine is provided. The system includes a pair of rail elements configured to be positioned laterally below and support the industrial machine, the rail elements allowing the industrial machine to be moved laterally from a first operative position to a second, maintenance position; and a pair of linear actuators configured to laterally move the industrial machine as from the first, operative position to the second, maintenance position. The rail elements may include a first skid configured to couple laterally to an underside of the industrial machine at a first axial position; and a second skid configured to couple laterally to an underside of the industrial machine at a second axial position. First and second segmented support rails are positioned in sliding, aligned contact with the first and second skid, respectively, and are configured to be supported on a respective machine foundation.
