摘要： Electrical machine (12) for a drive train (10) of a motor vehicle, having a housing section (34), having a stator (36) which is fixed in relation to the housing section (34) and has a stator core (40) to which the stator windings (38) are fixed, having a rotor (42) which is mounted such that it can rotate in relation to the stator (36), and having a stator cooling arrangement (50) for cooling the stator (36), wherein the stator cooling arrangement (50) has at least one cooling channel (52) which extends along a circumferential section of the stator (36) and through which a cooling fluid can be routed in a flow direction (54). In this case, a plurality of turbulence-generating elements (64) are arranged in the cooling channel (52), said turbulence-generating elements being arranged one behind the other in the flow direction (54) and/or offset in a manner in transverse to the flow direction (54) in the cooling channel (52), wherein at least some turbulence-generating elements (64) are formed by turbulence-generating projections (68; 70), of which at least one is integrally formed with the housing section (34) and/or of which at least one is integrally formed with the stator core (40), and wherein at least one of the turbulence-generating projections (68; 70) has a radial length which is equal to at least 70% of the radial depth of the cooling channel (52).
