Abstract
The motor-integrated fan has a suction port and a blowing port, and includes a rotating part rotatably supported on a shaft part; and a peripheral drive motor that rotates the rotating part by applying motive power from a duct provided on an outer peripheral side of the shaft part. The motor includes: a permanent magnet on a rotation support ring connected to the outer peripheral side of a blade of the rotating part; and a coil facing the permanent magnet in the axial direction of a rotational axis. In a cross-section taken on a plane orthogonal to the circumferential direction of the rotational axis, the center of gravity of a free end side portion including at least one of the rotation support ring and the permanent magnet is positioned closer to the suction port in the axial direction than the center of gravity of the thrust applied to the blade.
