  • FLUID COOLED STATOR
    Publication number: 20230198320
    Abstract: A stator is disclosed. The stator has a stator core that has stator poles protruding in a radial direction and a stator. The stator core has an axial groove formed on its outer surface along a longitudinal axis that is used to direct a cooling fluid from a first end of the stator core towards a second end of the stator core that is opposite the first end. Further, the stator core has an annulus groove formed on its outer surface, with the annulus groove in fluid communication with the axial groove. The annulus groove receives the cooling fluid from the axial groove, and is located between the first end and the second end of the stator core.
