An electric machine (1), comprising: a housing (2), in which a stator (3) and a rotor (4), which is rotatable relative to the stator (3), are accommodated, a cooling device with a cooling channel (5) through which a coolant can flow and which extends from an inlet (7), through the housing (2) and through the rotor (4), to an outlet (6), and a sealing device (18) for sealing off the rotor (4) with respect to an interior space (19) of the housing, wherein the sealing device (18) has a radial shaft sealing ring (11) which surrounds the rotor (4) and which delimits a reservoir (12) for coolant leakage. Additionally described are a drivetrain for a vehicle (14) having such an electric machine (1), and a method for operating the electric machine (1).
