The invention relates to a system for the oil cooling of an electrical machine (ME), comprising: a cooling circuit (OC) for bringing a cooling liquid into contact with the active parts of the electrical machine (ME); a tank (OT) for collecting the cooling liquid after it has cooled the active parts; a pump (OP) for re-injecting the cooling liquid upstream of the active parts; and a heat exchanger (HE). The cooling circuit (OC) comprises a branch pipe (BD) which diverts part of the cooling liquid upstream of the active parts such as to flow into the tank (OT) without passing through the active parts, the liquid volume of the tank (OT) being maintained constant. The cooling system comprises means (MA) for opening and closing the branch pipe (BD) according to a threshold temperature.
