The invention relates to an electric drive (10), in particular an electric motor of an engine-cooling fan or of an ABS/ESP of a motor vehicle, comprising an electric connector (22) and a housing (12), in the interior (14) of which a drive assembly (16) is arranged. The electric connector (22) has at least one electric line (41) contacting the drive assembly (16), an opening (20) is formed on the housing (12) for guiding through the electric line (41), and a seal (24) is arranged in the region of the housing opening (20). The electric line (41) has a first portion (50) and a second portion (52), the first portion (50) having a conductor (44) mid a sheath (48) encasing the conductor (44), and the second portion (52) being formed as an exposed conductor (44), the electric connector (22) having a sleeve-like element (42) in which the second portion (52) is arranged at least in part. According to the invention, the sleeve-like element (42) is connected in a fluid-tight manner to the second portion (52) and the seal (24) bears at least partially against the sleeve-like element (42), and the electric conductor (22) in the direction of its extent (54) is fluid-tight with respect to the housing interior (14) in the region of the sleeve-like element (42).
