Electric tractor for motor vehicle

The invention relates to an electric tractor (10) for a motor vehicle, comprising: a rotor (14) and a stator (16); a stator sleeve (18) into which the stator (16) is pressed; a housing (22), with which the stator sleeve (18) together delimits at least one pressure-oil cooling channel (26) and at least one water cooling channel (24), a compensation space (32) being left axially between the at least one pressure-oil cooling channel (26) and the water cooling channel (24) closest to the pressure-oil cooling channel, the compensation space is designed to collect oil exiting the pressure oil cooling channel (26). 本发明涉及一种用于机动车的电牵引机（10），所述电牵引机具有：转子（14）和定子（16）；定子套筒（18），所述定子（16）压入到所述定子套筒中；壳体（22），定子套筒（18）与所述壳体共同限定至少一个压力-油-冷却通道（26）和至少一个水冷却通道（24），其中，在轴向上在所述至少一个压力-油-冷却通道（26）和最接近该压力-油-冷却通道的水冷却通道（24）之间留出补偿空间（32），所述补偿空间设计用于收集从所述压力-油-冷却通道（26）离开的油。
