A motor integrated type fluid machine suctions a fluid from a suction port and discharges the suctioned fluid from a discharge outlet. The machine includes: a shaft portion provided at a center of a rotation axis; a rotating portion rotating around the shaft portion; an outer peripheral portion provided on an outer periphery of the shaft portion; and an outer peripheral drive motor rotating the rotating portion. The rotating portion includes a hub rotatably supported by the shaft portion, blades provided on an outer peripheral side of the hub and provided side by side in a circumferential direction of the rotation axis, and a rotating outer peripheral portion having an annular shape along the circumferential direction. A ratio of a rigidity of the rotating outer peripheral portion against a centrifugal force to a rigidity of the rotating portion against the centrifugal force is 50% to 95%.

An embodiment discloses a motor comprising: a stator; a rotor disposed to correspond to the stator; and a shaft coupled to the rotor. The rotor includes a rotor core coupled to the shaft, a plurality of magnets disposed outside the rotor core, and a can disposed to cover the rotor core and the magnets. The can includes a base, a body extending from the base in the axial direction, and a plurality of extension portions extending from the end portion of the body, wherein with reference to the radial direction, the radius R2 from the center C to the extension portions is longer than the radius R1 from the center C to the body. Accordingly, the motor can induce easy insertion of the magnets by using the can having two regions having different radii, thereby simplifying a manufacturing process of the motor and improving productivity thereof.
