Further, the second balance weight punching generally annular；Engraved in one side of something of second balance weight punching provided with inside Hollow structure.

Further, the first balance weight punching, the second balance weight punching are made up of silicon steel, copper alloy or kirsite, monolithic The scope of thickness is 0.3-3mm.

Further, rotor core is laminated by some rotor punchings and formed.

Further, the top and bottom of rotor core are respectively equipped with aluminium end ring and lower aluminium end ring；Upper aluminium end ring is located at Balanced on rotor between lamination and rotor core, lower aluminium end ring is located under rotor between balance lamination and rotor core.

Further, the top and bottom of rotor core are respectively equipped with copper end ring and lower copper end ring；Upper copper end ring is located at Balanced on rotor between lamination and rotor core, lower copper end ring is located under rotor between balance lamination and rotor core.

Relative to prior art, the utility model has the advantages that：The utility model is by setting internal hollow out Constitutional balance block punching laminates the integral type rotor balancing block structure to form certain altitude and weight, eliminates the projection of balance weight Part, reduces the disturbance to compressor electric motor lower space when rotor rotates at a high speed, reaches elimination balance weight windage, reduction Power consumption and the effect with oil mass, improve compressor capacity, and motor rotor balance weight structure is become simple and highly versatile. And balance block structure is become simple using lamination, manufacturability is greatly improved.

Further, it is different by the quantity of used balance weight lamination, to meet the balance weight of different weight requirement Counterweight requirements.
