Abstract: A lamination for a stator of an electric motor includes: a material sheet having a generally circular shape with a center and a radial direction, an outer contour, and an inner contour, the outer and inner contours being generally concentric with the center. The inner contour is defined by an arrangement of a plurality of teeth and a plurality of stator slots, each tooth of the plurality of teeth having one stator slot of the plurality of stator slots to a first side of the tooth and one stator slot of the plurality of stator slots to a second side of the tooth, the inner contour defining a rotor hole for receiving a rotor of the electric motor. The material sheet has a plurality of internal cooling holes arranged around the rotor hole.

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.
