Claim 18:
19. An electric motor comprising:
a housing;
a stator assembly disposed in the housing;
a rotor assembly rotatably disposed in the stator assembly;
an impeller configured to be rotated by the rotor assembly and to generate a flow of air;
a first bearing and a second bearing that are spaced apart from each other, the impeller being disposed between the first bearing and the second bearing;
a first housing cover that is disposed at a first side of the housing and accommodates the first bearing therein;
a second housing cover that is disposed at a second side of the housing and accommodates the second bearing,
wherein the stator assembly defines an inner flow path configured to guide a part of the air to pass through an inside of the stator assembly, and
wherein the housing defines a bypass flow path at an outside of the stator assembly, the bypass flow path being configured to guide another part of the air to bypass the stator assembly,
wherein the housing comprises:
a first flange that protrudes outward from the second side of the housing in a radial direction; and
a second flange that protrudes outward from a side of the second housing cover in the radial direction, the side of the second housing cover facing the second side of the housing in an axial direction, and

wherein the first flange overlaps with the second flange along the axial direction and is coupled to the second flange.
