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 회전자에는 영구자석이 삽입되는 복수 개의 슬롯이 원주 방향을 따라 이격 형성되고, 상기 슬롯의 양측 단부에는 냉각홀이 형성되되, 상기 슬롯과 상기 냉각홀은 공간적으로 구분되고, 냉매가 상기 냉각홀로 유동하여 상기 영구자석을 냉각시키는 전동 압축기를 제공한다. 이에 의하여, 회전자의 영구자석 냉각 성능이 향상될 수 있다.

    The present invention provides an electric compressor comprising: a rotating shaft which drives a compression mechanism; a rotor in which a rotating shaft through-hole for insertion of the rotating shaft is formed; a cover which covers the longitudinal end of the rotor; and a stator which is provided radially outside the rotor, wherein: the rotor has a plurality of slots which are formed to be spaced apart from each other in the circumferential direction and into which permanent magnets are inserted, respectively; each of the slots has cooling holes formed at both ends thereof, the slot and the cooling holes being spatially separated from each other; and a coolant flows through the cooling holes to cool the permanent magnets. Accordingly, the cooling performance of the permanent magnets of the rotor can be improved.
