Abstract
Various methods and systems are provided for thermal management of an electric motor via a coolant flow around portions of the electric motor, where the coolant flow is disrupted by an arrangement of pin-fins. In one example, an electric motor comprises: a casing including a coolant inlet arranged opposite to a coolant outlet across a central axis of the electric motor; a stator housed within the casing and forming a plurality of pin-fins extending straight outward radially, relative to the central axis, from outer circumferential surfaces of the stator in a staggered arrangement around an entire perimeter of the stator; and a plurality of clearances formed between adjacent pin-fins of the plurality of pin-fins, the plurality of clearances adapted to flow a coolant from the coolant inlet to the coolant outlet.
