A stator assembly of an electric motor comprising:
- a plurality of ring structures centered to an axis, each of the plurality of ring structures including a ring and a plurality of cooling fins projecting radially from and spaced circumferentially about the ring, wherein each of the plurality of ring structures is disposed axially adjacent to another one of the plurality of ring structures.
An electric motor comprising:
- a rotor adapted for rotation about an axis;
- and
- a stator assembly surrounding the rotor, the stator assembly including:
- windings;
- a first ring structure disposed radially outward from and concentric to the rotor, the first ring structure including a first ring and a first plurality of cooling fins spaced circumferentially about and projecting radially from the first ring;
- and
- a second ring structure disposed radially outward from and concentric to the rotor, the second ring structure including a second ring and a second plurality of cooling fins spaced circumferentially about and projecting radially from the second ring, wherein the first ring structure is axially adjacent to the second ring structure.
