Zusammenfassung:	The present invention relates to an electric motor and an electric supercharger having the same. The electric motor according to the present invention includes a stator; and a rotor rotatably disposed with respect to the stator. The rotor includes a rotating shaft; and an air flow generation part which has a plurality of air flow protrusions protruding from the outer surface of the rotary shaft along the radial direction and spaced apart from each other in the circumferential direction and moves the air when the rotor rotates. As a result, cooling can be performed and the increase of a load due to the generation of air flow can be suppressed. 본 발명은 전동기 및 이를 구비한 전동식 과급기에 관한 것이다. 본 발명의 전동기는, 스테이터; 및 상기 스테이터에 대해 회전 가능하게 배치되는 로터;를 포함하고, 상기 로터는, 회전축; 및 상기 회전축의 외면으로부터 반경방향을 따라 돌출되고 원주방향을 따라 이격된 복수의 공기유동돌기를 구비하고, 상기 로터의 회전 시 공기를 유동시키는 공기유동발생부;를 구비하여 구성된다. 이에 의해, 냉각이 가능하고 공기 유동 발생에 기인한 부하 증가를 억제할 수 있다.
