The present invention relates to a turbo machine and, specifically, to a cooling structure for a motor driving a turbo machine such as a turbo compressor, a turbo blower, and a turbo fan. The turbo machine according to an embodiment of the present invention comprises: a driving part having a rotor and a stator; a compressing part having an impeller which is rotated by being interlocked with the rotor; a guide pipe guiding a driving part cooling fluid, which flows into the driving part and is discharged to the outside through the driving part, to the compressing part; and an external fluid inlet pipe installed at one side of the guide pipe and connected to the guide pipe in order to allow a predetermined fluid to flow into the guide pipe. [Reference numerals] (AA) Inhale compressed air; (BB) Join outdoor inhaled air and motor cooling air; (CC) Inhale the motor cooling air; (DD) Discharge the compressed air
