The invention provides a rotor assembly and a compressor. The rotor assembly comprises a rotor iron core; the oil baffle cap is connected with one end of the rotor iron core, guide vane structures are arranged on the surface, facing the rotor iron core, of the oil baffle cap, a mounting through hole is formed in the middle of the oil baffle cap, the number of the guide vane structures is multiple, and the guide vane structures are arranged in the circumferential direction of the mounting through hole at intervals; the at least one guide vane structure is arranged in the radial direction of the oil blocking cap according to a preset angle in an offset mode. By means of the arrangement, the flow guiding effect of the guide vane structure on refrigerants can be improved, then the oil-gas separation effect of the oil blocking cap on the refrigerants is improved, the oil spitting rate of the compressor with the rotor assembly is reduced, and the stability and reliability of the compressor are effectively improved.
