Systems for eccentric annular cover for stator end windings

A system comprising:

• a stator including:
• a stator core;
• one or more windings, wherein the one or more windings include one or more end windings extending from a longitudinal end of the stator core;
• and
• a cover for the one or more end windings and to be disposed around a rotor, wherein the cover is configured to transfer a cooling fluid to cool the one or more end windings, and wherein the cover includes:
• a body to cover the one or more end windings, the body including a cavity for the cooling fluid;
• an inlet disposed in the body for the cooling fluid to enter the cavity;
• and
• an outlet disposed in the body for the cooling fluid to exit the cavity, wherein the outlet is disposed at a portion of the body opposite to the inlet,
• wherein a first radial width of the cavity at the inlet is greater than a second radial width of the cavity at the outlet.
