The present invention relates to an electric machine with a radial shaft sealing ring. 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 (18) for sealing the rotor (4) against the inner space (19) of the housing. The sealing device (18) surrounds the rotor (4), and has a radial shaft sealing ring (11) limiting a storage (12) for a leaked cooling agent. Additionally explained are a drive train for a vehicle (14) having the electric machine (1) and a method for operating the electric machine (1). The present invention is able to reduce maintenance 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, 하우징의 내부 공간(19)에 대해 로터(4)를 밀봉하기 위한 실링 장치(18)를 포함하며, 실링 장치(18)는 로터(4)를 둘러싸고, 냉각제 누출물을 위한 저장소(12)를 한정하는 반경방향 샤프트 시일 링(11)을 구비한다. 이러한 전기 기계(1)를 구비하는 차량(14)용 드라이브트레인과, 전기 기계(1)를 작동시키는 방법이 추가로 설명된다.
