Abstract
A compressor includes a drive motor and a wind wheel, wherein the drive motor includes a casing and a rotor, the rotor being rotatably arranged within the casing; the wind wheel is mounted at a first axial end of the rotor. A thrust disc is also provided at the first axial end of the rotor. An axial bearing assembly is arranged between the thrust disc and the wind wheel, and the axial bearing assembly is arranged fixedly with respect to the casing. A first air gap is formed between a first end of the axial bearing assembly and the wind wheel, and a second air gap is formed between a second end of the axial bearing assembly and the thrust disc. The air compressor reduces a tolerance accumulation caused by part cooperation between axial bearing assemblies, and more precisely ensures effective working clearances.
