Abstract

An electric machine (EM) comprising a housing (H) defining an accommodation space, provided with an oil inlet (IN) communicating with the accommodation space; a stator core (ST) defining a rotation axis (X) arranged in the accommodation space, comprising oil flow guide disk (D) arranged in an intermediate position of the stator along the rotation axis, wherein the oil flow guide disk includes annular oil channels (G1, G2) for directing oil received by the inlet (IN) in axial channels (XC1, XC2) defined in the stator core; wherein the axial oil channels are arranged in two or more groups (G1, G2) according to a relating radial position in the stator core, wherein the oil flow guide disk (D) is designed to connect the two or more groups in parallel between each other, such that oil flows only from the flow guide disk (D) towards end faces (EF1, EF2) of the stator core and wherein the axial channels are open at the opposite end faces of the stator core (ST).
