Motor integrated type fluid machine, vertical take-off machine and method for designing motor integrated body motor

摘要

Problem to be solved: to secure the load against centrifugal force while suppressing weight increase.Suction fluid from the suction portIn a motor integrated fluid machine that blows a sucked fluid out of the outletAxis at the center of the shaftA rotating part around a shaftThe outer circumference of the shaftMotor rotating the rotating partEquipped withMotor isIt is an outer circumference driving motor which rotates the rotating part by giving power from the outer circumference.The rotating partA hub supported rotatably about the shaftMultiple blades on the outer circumference of the hubAn annular circumference around a plurality of bladesAndMotor isRotor side magnet provided at the circumference of rotationProvided on the outer circumferenceStator side magnet provided opposite rotor side magnetAndThe rigidity of the outer circumference of the rotor against centrifugal force isFor the stiffness of the rotating part against centrifugal forceIt has a rigidity ratio of 50% or less and 95% or less.Diagram
