Zusammenfassung:The present invention relates to a rotating electric machine which comprises: a stator; a rotor which is rotatably placed around a rotation shaft toward the stator; a case which is made from a thermal conductor and accommodates the stator; a cooling fan which is placed in the rotor; a circuit unit which is placed outside the case; and a circuit unit cooling unit which comprises a base which is made from a thermal conductor and has a circuit unit mounting surface on one side surface on which the circuit unit is mounted, and a cooling fin which is made by bending a strip of a thermal conductor in a wavy form and is mounted on the other side surface of the base and is combined with one side of the case. As such, the present invention can improve cooling efficiency without increasing the size of the exterior. 본 발명은 회전전기기계에 관한 것으로서, 스테이터; 상기 스테이터에 대해 회전축을 중심으로 회전가능하게 배치되는 로터; 열전도체로 형성되어 상기 스테이터를 내부에 수용하는 케이스; 상기 로터에 구비되는 냉각팬; 상기 케이스의 외부에 구비되는 회로부; 및 열전도체로 형성되고 일 측면에 상기 회로부가 장착되는 회로부장착면이 구비되는 베이스 및 열전도체의 스트립을 파형으로 절곡하여 형성되고 상기 베이스의 타 측면에 장착되는 냉각핀을 구비하고, 상기 케이스의 일 측에 결합되는 회로부냉각유닛;을 구비하여 구성된다. 이에 의해, 외관 크기를 증대시키지 아니하고 냉각성능을 제고시킬 수 있다.
