Abstract: A motor-integrated fan sucks air from a suction port and blows out the sucked air from a blow-out port. The motor-integrated fan includes a shaft part that is provided at a center of a rotational axis; a rotation part that is rotated about the shaft part; an outer peripheral part that is provided on an outer periphery of the shaft part; a motor that rotates the rotation part; a heat generating part that generates heat due to an operation of the motor; and a cooling unit that cools the heat generating part with cooling air. The cooling unit includes an air intake port that takes the cooling air in, an air discharge port that discharges the cooling air, and a cooling flow channel that leads to the air discharge port from the air intake port via the heat generating part.

Abstract: A motor-integrated fan 1 including one or more motors integrated therein comprises: a shaft part 11 which serves as a supporting system disposed at the center of a rotational axis; a rotation part 12 which is a rotating system rotating about the shaft part 11; a duct 13 which serves as a supporting system provided on the outer periphery of the shaft part 11; and a motor 14 which rotates the rotation part 12, wherein the rotation part 12 comprises: a plurality of blades 32 rotatably supported at least on the shaft part 11 and rotating thereabout, the blades 32 being arranged in a circumferential direction of the rotational axis I; and a rotation support ring 33 connected on one side of each of the blades 32 in a radial direction of the rotational axis, the rotation support ring 33 supporting the plurality of blades 32.
