Abstract: A fan motor includes a motor mount, a motor part accommodated in an inner space of the motor mount, and an impeller disposed above the motor mount. The motor mount defines: an air discharge opening configured to discharge air discharged from the impeller to an outer space of the motor mount; a cooling flow path outlet disposed at the upper side of the motor mount at a position between the impeller and the air discharge opening; and a first cooling flow path inlet disposed at a position below the air discharge opening and the cooling flow path outlet. The fan motor further includes a guide that is configured to direct, to an upward direction, at least a portion of air that is discharged through the air discharge opening and introduced to the inner space through the first cooling flow path inlet.

Abstract: A fan motor is provided that includes an inner housing having an inner space formed therein; a rotational shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotational shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotational shaft; and an outer housing that surrounds an outer periphery of the inner housing and having an inlet body that guides air to the impeller. At least one heat dissipation vane is provided on an outer peripheral surface of the inner housing to guide air which passes between the inner housing and the outer housing after being suctioned into the inlet body, and thus, when being guided by the at least one heat dissipation vane, the air having been moved by the impeller may efficiently absorb heat transferred from the stator to the at least one heat dissipation vane and more stably flow than when colliding against the stator and the rotor, and thus, may be quickly discharged.

Abstract: An electric motor includes a housing, a stator assembly disposed in the housing, a rotor assembly rotatably disposed in the stator assembly, and an impeller configured to be rotated by the rotor assembly and to generate a flow of air. 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. The housing defines a bypass flow path at an outside of the stator assembly, where the bypass flow path is configured to guide another part of the air to bypass the stator assembly.
