The present invention relates to an air compressing system which compresses air by an eccentric rotation of a rotor interlocked or directly connected to a motor of a high output or a high speed rotation and, more specifically, comprises the motor and a compressor connected to the motor. The compressor, as a hollow structure, comprises: a casing having an inlet and an outlet on the outer circumferential surface; and the rotor rotated while a rotary shaft interlocked with the motor is eccentrically rotated. The air compressing system discharges high-pressure air through the outlet as the air, which is entered through the inlet, is compressed by the rotation of the rotor. The present invention manages a rotational balance of the rotor by forming at least one or more through holes penetrated toward the rotary shaft on a heavier side based on a center line (CL), which connects the rotating center of the rotary shaft of the rotor and the center of the rotor body, and a perpendicular line (CV). Therefore, the air compressing system can reduce noise and vibration as much as possible when the rotor rotates by having a more perfect rotating balance of the rotor. |
