Zusammenfassung:The present invention relates to an electric supercharger, comprising: an impeller (400) sucking and compressing the air and discharging the compressed air; a driving portion for rotating the impeller; a cooling means formed at the outside of the driving portion and cooling the driving portion; and a flow path supplying the compressed air at the rear end of the impeller (400) to the driving portion so as to cool the driving portion. According to the present invention, a part of the compressed air in a volute portion or the rear end of the impeller is used for cooling an electric motor such that the cooling efficiency of the electric motor can be improved. 본 발명은 전동 슈퍼차저에 관한 것으로, 공기를 흡입 및 압축하여 토출하는 임펠러(400); 상기 임펠러를 회전시키기 위한 구동부; 상기 구동부 외측에 형성되어 상기 구동부를 냉각하는 냉각 수단; 상기 임펠러(400) 후단의 압축 공기를 상기 구동부에 공급함으로써 상기 구동부를 냉각하기 위해 형성된 유로를 포함한다. 본 발명에 따르면, 볼루트부 또는 임펠러 후단의 압축 공기 일부를 전동모터의 냉각에 활용함으로써 전동모터의 냉각 효율을 향상시키는 효과가 있다.
