摘要： This disclosure provides a consolidated electric motor stator lamination for multiple enclosure types such that a single stator assembly can be used for different classifications of an electric motor. Each layer of the stator lamination includes external features that, when combined with the external features of the other layers in the lamination, can be adapted to conform the electric motor to one of a plurality of enclosure types. The external features include retaining features for one or more covers, fins, and a profile configured to accept cooling tubes. In various embodiments, a single consolidated stator lamination assembly can be adapted to provide a motor having at least two of an open-drip proof (ODP), a totally enclosed fan cooled (TEFC), or a totally enclosed water cooled (TEWC) enclosure classification.

摘要： A stator for an electric motor includes a yoke and a star disposed in the yoke. The star is configured to receive a rotor therein and has at least one wire coiled thereat. The yoke and the star are configured such that the star is axially insertable into the yoke with reduced interference and reduced insertion force. The star is axially inserted into the yoke in an unlocked position. When the star is inserted into the yoke, the star is rotatable to a locked position, whereby the star is retained at the yoke via an interference fit.

摘要： A support assembly for servicing a stator frame of a power generator includes a plurality of rails and a trolley. The rails are supported on frame rings of a main housing of the stator frame. The rails have upper surfaces that provide temporary support for lower support surfaces of second laminations of a second stator core once the second laminations are inserted into desired axial positions within the main housing. The trolley is provided for axial movement on the upper surfaces of the rails for inserting the second laminations into the main housing. The trolley includes a lamination-engaging portion including a lamination support surface for supporting upper support surfaces of the second laminations and a plurality of rail wheels provided for axial movement of the trolley within the main housing on the upper surfaces of the rails.
