Centrifugal high-speed air compressor

The utility model provides a centrifugal high-speed air compressor, and particularly relates to the technical field of air compressors, the centrifugal high-speed air compressor comprises a high-speed motor and a compression assembly connected with a motor shaft of the high-speed motor; the compression assembly comprises an impeller and a shell, an air suction port and an exhaust port are formed in the shell, and an air inlet and an air outlet are formed in the motor shell; when an impeller on the compression assembly rotates at a high speed along with a motor shaft of the high-speed motor, first airflow which enters from an air suction port and is exhausted from an air outlet is formed in a shell of the compression assembly, and meanwhile, the first airflow which enters from the air suction port and then flows into the shell of the motor through the air inlet is formed; and the second airflow carries heat generated in the working process of the motor assembly and is discharged through the air outlet.
