Fan motor

A fan motor, comprising:

• a housing;
• a stator assembly disposed inside the housing;
• a rotor assembly rotatably disposed inside the stator assembly;
• an impeller configured to generate a flow of air in the housing based on receiving power from the rotor assembly, the impeller being a diagonal flow impeller;
• a first housing cover disposed at one side of the housing;
• a first bearing disposed in the first housing cover;
• a second housing cover disposed at another side of the housing and configured to guide the flow of the air along an axial direction of the impeller, the impeller and the second housing cover being arranged along the axial direction;
• a second bearing disposed in the second housing cover;
• and
• a vane assembly disposed at a lower portion of the second housing cover and configured to guide the flow of the air in the second housing cover,
• wherein the housing comprises:
• a first accommodating portion that accommodates the rotor assembly and the stator assembly,
• a second accommodating portion that is disposed vertically below the first accommodating portion and accommodates the impeller,
• a neck portion disposed between the first accommodating portion and the second accommodating portion, a diameter of the neck portion being less than a diameter of the first accommodating portion, and
• an inclined portion that is inclined with respect to the first accommodating portion and extends from the first accommodating portion toward the neck portion.
