Abstract: 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.
