Stator structure of electric compressor

Abstract

The invention discloses a stator structure of an electric compressor. The stator structure is characterized in that: the stator structure is installed in an inner shell ring after a motor stator core is sleeved on a motor rotating shaft; the cross section of the motor stator core is square and round; and the cross section of the inner shell ring is round. With the adoption of the structure, the stator structure has the advantages as follows: 1, the structural manufacturability of a motor spindle and a die-casting aluminum shell is improved on the premise of not influencing the performances of a motor; 2, the flow resistance is reduced and the compressor efficiency is improved; and 3, the material utilization rate of stator silicon sheets is improved so as to reduce the cost of the entire machine.

Description

[0001] Involved areas [0002] The invention relates to the field of automobile air conditioners, in particular to a stator structure of an electric compressor. Background technique [0003] With the development of the economy and the improvement of people's living standards, cars have entered thousands of households. With the popularization of automobiles, automobile air conditioners are gradually familiar to people. [0004] In the electric compressor, the refrigerant needs to be compressed and flowed to complete the state change and energy transmission. Generally, the motor shaft is processed into a hollow as the refrigerant flow channel or the inner ring of the casing is made into an uneven shape, and the concave part As a refrigerant flow channel. These two structures have certain defects. The former is restricted by the structure, the shaft cannot be too thick, the flow channel section cannot be larger, the refrigerant path is tortuous, the flow resistance is large, th...

Problems solved by technology

These two structures have certain defects. The former is restricted by the structure, the shaft cannot be too thick, the flow channel section cannot be larger, the refrigerant path is tortuous, the flow resistance is large, the shaft is processed into a hollow process, and the strength and rigidity of the shaft structure are not good. ;The structure of the inner and outer circles of the latter case is uneven, and the manufacturability is poor when the inner circle is discontinuous.
