An oil cooling system for an electric machine that includes a housing and a stator accommodated in the housing, the stator having a first end part and a second end part in an axial direction of the electric machine. The oil cooling system includes an oil inlet, for receiving external cooling oil; a first annular oil application pipe, located at the first end part and in fluid communication with the oil inlet; and a second annular oil application pipe, located at the second end part and in fluid communication with the oil inlet. An axial oil application part is located between the first end part and the second end part and formed by a housing inner wall and a stator outer wall. The axial oil application part receives cooling oil from at least one of the first annular oil application pipe and the second annular oil application pipe.
