摘要： An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. In order to improve end winding cooling uniformity, two or more end laminations are included on either end of the stator assembly which restrict and direct the flow of coolant exiting the axial coolant channels.

摘要： A rotor fabrication method is provided. The rotor uses pre-fabricated conductive rotor bars in which the ends have been shaped and sized to fit within corresponding end cap receptacles. After assembly, the structure is compressed, thereby achieving mechanical and electrical coupling between the conductive rotor bars and the end caps. Locking members disposed at either end of the assembly maintain the desired level of axial compressive force on the structure.

摘要： An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. The coolant manifold includes a middle member that allows coolant to enter the axial coolant channels via transition laminations, where the transition laminations include coolant distribution channels that direct the flow of coolant entering into the manifold into the stator-integrated axial coolant channels.

摘要： A method of manufacturing an electric motor that includes a plurality of structural cooling features is provided, where the electric motor utilizes axial cooling channels integral to the stator teeth, thus allowing direct contact between the circulating coolant and the lamination stack. A coolant manifold assembly, incorporated into the stator between left and right stator portions, provides a means of distributing coolant to the axial cooling channels.

摘要： An electric motor cooling system is provided utilizing axial cooling channels that are integral to the stator teeth, thus allowing direct contact between the circulating coolant and the lamination stack and providing an efficient means of removing motor assembly heat. Additionally, as the coolant flows out of the cooling channels it impinges on the end windings, thereby providing a secondary means of cooling the motor assembly.

摘要： A rotor fabrication method is provided, along with the resultant rotor assembly. The rotor uses pre-fabricated conductive rotor bars in which the ends have been shaped and sized to fit within corresponding end cap receptacles. After assembly, the structure is compressed, thereby achieving mechanical and electrical coupling between the conductive rotor bars and the end caps. Locking members disposed at either end of the assembly maintain the desired level of axial compressive force on the structure.

摘要： A motor assembly with an integrated cooling system is provided in which a coolant (e.g., oil) is injected into a hollow region of the rotor shaft. The coolant is expelled out of the rotor shaft and into the motor enclosure via multiple thru-holes, thereby allowing efficient cooling of both the stator and the rotor assemblies.

摘要： A gear assembly is provided that simplifies the integration of a differential assembly into the hollow rotor of an electric motor. The gear assembly utilizes a hollow cross member that includes a central portion and a plurality of hollow extension members onto which the gears are mounted. Within each of the hollow extension members is a pin. When the pins are withdrawn, the assembly fits unimpeded within the hollow rotor. When the pins are partially extended out of the corresponding extension members, the ends of the pins fit within apertures in the rotor. A plug fits within a centrally located thru-hole in the central portion of the hollow cross member, thereby locking the pins in the extended position and locking the gear assembly in place.
