The present invention relates to an electric machine with a sleeve on an end unit section of a rotor. 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 end unit section of the rotor (4) is surrounded by the sleeve (10) surrounded by a radial shaft sealing ring (11) of the sealing device (21). Additionally explained are a drive train for a vehicle (17), a vehicle of the above type (17), and a method for operating the electric machine (1). The present invention is able to provide an electric machine which can be operated for a long time without suspension.

    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(22)에 대해 로터(4)를 밀봉하기 위한 실링 장치(21)를 포함하며, 로터(4)의 단부 섹션은 실링 장치(21)의 반경방향 샤프트 시일 링(11)에 의해 둘러싸인 슬리브(10)에 의해 둘러싸인다. 차량(17)용 드라이브트레인과, 상기 유형의 차량(17)과, 전기 기계(1)를 작동시키는 방법이 추가로 설명된다.
