Abstract
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.
