[0002] A compressor is a key component of a refrigeration system. The motor drives the crankshaft to rotate. Through the transmission of the connecting rod, the piston reciprocates up and down in the cylinder, and under the cooperation of the suction and exhaust valves, the refrigerant is inhaled, compressed, and transported. The main component of the compressor motor stator component is the stator core, which is formed by stacking a certain number of silicon steel sheets after being stamped into stator punchings in a specific shape. The shape of the stator core affects the consumption of silicon steel, the complexity of the stamping die, and the processing efficiency. In existing compressors, the motor stator core and the cylinder block are generally fixed by screws, that is, the screws pass through the stator core and are fixed to the stator feet of the cylinder block. In order to cooperate with the screw fastening of the stator feet of the cylinder block, the radial dimension of the stator core is relatively large to reserve a sufficient contact and cooperation area at the part where it cooperates with the stator feet of the cylinder block, resulting in more consumption of stator punchings and higher costs. In addition, when installing the skeleton and winding the wire on the existing stator core, positioning needs to be carried out according to the stator core, and the assembly operation is more difficult.
