Title:
MOTOR-INTEGRATED FLUID MACHINE AND VERTICAL TAKE-OFF AND LANDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/158361
Kind Code:
A1
Abstract:
This motor-integrated fan has a suction port and a blowing port, and is provided with: a rotating part rotatably supported on a shaft part; and a motor that rotates the rotating part. The motor is 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 provided on a rotation support ring connected to the outer peripheral side of a blade of the rotating part; and a coil provided 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 a rotational axis I, the center of gravity (point P2) of a free end side portion including at least one of the rotation support ring and the permanent magnet is positioned more to the suction port side in the axial direction of the rotational axis I than the center of gravity (point P1) of the thrust applied to the plurality of blades.
