The invention discloses a rotor short-circuit ring combined structure and a processing method thereof. The rotor short-circuit ring combined structure comprises a rotor core, two porous ring sheets, aplurality of conductive copper sheets, a wire ring, two proper circular rings and two short-circuit rings; the porous ring sheets are respectively connected in series with two ends of the rotor core;after the wire ring is connected with the conductive copper sheets one by one in a stringed manner, the conductive copper sheets are inserted into the rotor core and the porous ring sheets, the two ends of each conductive copper sheet protrude out of the axial cross section of the rotor core; the conductive copper sheets are arranged in a perfect circle through the cooperation with the constraintof the proper circular rings; and the short circuit rings are integrally formed at the two tail ends of the rotor core and the conductive copper sheets through a casting process. By means of the composition of the components,
