1. An arrangement for liquid cooling of an electric machine with a stator and a rotor, comprising:
a cooling jacket configured to enclose an outer circumference of the electric machine and having an input and an output, wherein the cooling jacket is further configured to guide a cooling medium that enters the cooling jacket at the input to the output,
wherein, in an installed position of the electric machine, the input is arranged spatially below a rotational axis of the rotor and circumferentially offset from a vertical plane through the rotational axis of the rotor, and the output is arranged spatially above the rotational axis.
