The present invention provides an electric compressor, comprising: a rotating shaft that drives a compression mechanism; a rotor in which a rotating shaft through hole is formed for inserting the rotating shaft; a cover for covering a longitudinal end of the rotor; and a stator installed radially outside the rotor, wherein a cooling passage is formed diagonally in the rotating shaft through hole, and the rotor is cooled by refrigerant passing through the cooling passage. Therefore, the cooling performance of a motor can be improved.
본 발명은, 압축기구를 구동시키는 회전축; 상기 회전축이 삽입되기 위한 회전축 관통공이 형성되는 회전자; 상기 회전자의 길이방향 단부를 덮는 커버; 및 상기 회전자의 반경방향 외측에 설치되는 고정자를 포함하고, 상기 회전축 관통공에는 냉각 유로가 사선형으로 형성되어, 냉매가 상기 냉각 유로를 통과함으로써 상기 회전자가 냉각되는 전동 압축기를 제공한다. 이에 의하여, 모터의 냉각 성능이 향상될 수 있다.
