Abstract
A stator assembly () includes a stator core () defining an outside diameter (OD) and an inside diameter (ID) with longitudinally extending slots () formed between the inside diameter and the outside diameter. The stator core () defines a core height extending longitudinally from a first end () to a second end () of the stator core (). Distributed windings () are retained by the stator core () and include an in-slot portion () positioned in the slots of the stator core (), a first end turn portion () adjacent to the first end () of the stator core, and a second end turn portion () adjacent to a second end () of the stator core. The first end turn portion () defines a first end turn height (h) extending from the first end () of the stator core to a vertex () of the first end turn portion (). A ratio of the first end turn height (h) to the outside diameter (OD) of the stator core is less than or equal to 0.07.
