Abstract

A motor-integrated fluid machine includes a rotatable part configured to rotate around a rotation axis; an outer peripheral part at an outer periphery of the rotatable part; a motor configured to provide power from the outer peripheral part to rotate the rotatable part; and a restrainer part. The rotatable part includes a support ring around the rotation axis, and blades on a center side of the support ring. The blades are side by side in a circumferential direction. The motor includes a rotor side magnet on an outer peripheral side of the support ring in a radial direction, and a stator side magnet on an inner peripheral side of the outer peripheral part to face the rotor side magnet. The restrainer part is configured to restrain the support ring and the rotor side magnet from outside to integrate the support ring and the rotor side magnet.
