The present invention relates to an electric machine with a storage for a leaked cooling agent. According to the present invention, the electric machine (1) comprises: a housing (2) accommodating a stator (3) and a rotor (4) rotatable around the stator (3); a cooling device having a cooling channel (5) in which a cooling agent can flow and which is extended from an inlet (7) to an outlet (6) through the housing (2) and the rotor (4); and a sealing device (21) for sealing the rotor (4) against the inner space (22) of the housing. The storage (12) for a leaked cooling agent generated while the rotor (4) is rotating is formed between the sealing device (21) and the housing (2). Additionally explained are a drive train and a vehicle (17) having the electric machine (1) and a method for operating the electric machine (1). The present invention is able to reduce operation cost.

    전기 기계(1)는 스테이터(3) 및 스테이터(3)에 대해 회전 가능한 로터(4)가 수용되는 하우징(2)과, 냉각제가 유동할 수 있고 유입구(7)로부터 하우징(2) 및 로터(4)를 통해 유출구(6)로 연장되는 냉각 채널(5)을 구비한 냉각 장치와, 하우징(2)의 내부 공간(22)에 대해 로터(4)를 밀봉하기 위한 실링 장치(21)를 포함하며, 로터(4)의 회전 동안에 발생하는 냉각제 누출물을 위한 저장소(12)는 실링 장치(21)와 하우징(2) 사이에 형성된다. 드라이브트레인 및 이러한 전기 기계(1)를 구비하는 차량(17), 및 전기 기계(1)를 작동시키는 방법이 추가로 설명된다.
