ABSTRACT:
The present disclosure, in one form, provides an electric motor/generator low hydraulic resistance cooling mechanism including a hollow cooling stator case having an inner and outer coaxial surface. The inner surface defines a generally cylindric cavity for receiving a stator in heat transference contact with the inner surface. The outer surface has integrated spiral groove cooling passages that are defined by filleted rectangular cross sections.
