Title:
MOTOR INTEGRATED TYPE FLUID MACHINE, VERTICAL TAKE-OFF AND LANDING AIRCRAFT, AND DESIGN METHOD FOR MOTOR INTEGRATED TYPE FLUID MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/131196
Kind Code:
A1
Abstract:
This motor integrated type fluid machine for taking in a fluid from an inlet port and blowing out the taken-in fluid from a blowout port, is provided with: a shaft part that is provided at the center of a rotary axis; a rotation part that is rotated about the shaft part; an outer circumference part that is provided to the outer circumference of the shaft part; and a motor that rotates the rotation part. The motor serves as an outer circumference driving motor that causes the rotation part to be rotated by receiving motive power from the outer circumference part. The rotation part has: a hub that is rotatably supported by the shaft part; a plurality of blades that are provided to the outer circumference side of the hub; and an annular rotation outer circumference part that is provided to the outer circumference sides of the plurality of blades. The motor has: a rotor side magnet that is provided to the rotation outer circumference part; and a stator side magnet that is provided to the outer circumference part and that is provided so as to oppose the rotor side magnet. The ratio of the rigidity of the rotation outer circumference part with respect to a centrifugal force, with respect to the rigidity of the rotation part with respect to a centrifugal force is 50-95%.
