Abstract: A cooling frame for cooling an electric motor is provided. The cooling frame includes a header and a plurality of fluid conduits configured to carry a fluid and facilitate an exchange of heat between the fluid and the electric motor. The header includes at least one header port for exchanging fluid into or out from the header; a first plate comprising a central opening; and a plurality of conduit ports on the first plate positioned around the central opening, wherein each conduit port is fluidly connectable to a respective fluid conduit of the plurality of fluid conduits. The header also includes a first channel fluidly connecting the at least one header port and a first conduit port of the plurality of conduit ports, and a second channel fluidly connecting a second conduit port and the at least one header port.

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.

IPC: H02K5/04
CPC classification number: H02K5/04
Abstract: An electric machine includes: a stator with an outer and an inner surface; a rotor disposed inside the inner surface of the stator and configured to rotate about an axis of rotation; a shaft oriented along and configured to rotate about the axis of rotation of the rotor and operably connected to the rotor; a frame integrated with the stator such that an outer surface of the frame is identical to the outer surface of the stator or a frame disposed outside the stator; and at least one fastenerless cover fixed to the outer surface of the frame without the use of fasteners.

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.
