1. An electric motor comprising:
a housing;
a stator assembly disposed in the housing;
a rotor assembly rotatably disposed in the stator assembly, the rotor assembly comprising a rotating shaft and a permanent magnet disposed at the rotating shaft;
a first bearing and a second bearing that are spaced apart from each other, the permanent magnet 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
an impeller configured to be rotated by the rotor assembly and to generate a flow of air,
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,
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, and
wherein the second housing cover comprises:
an outer cover,
an inner hub disposed inside the outer cover, and
a plurality of vanes that connect the inner hub to the outer cover, the plurality of vanes protruding from an outer circumferential surface of the inner hub to an inner circumferential surface of the outer cover.
