The invention relates to an electric motor, in particular for a motor vehicle, comprising a housing (), a shaft () having an axle (), a stator and a rotor, at least one channel () for conducting a coolant for cooling the electric motor (), wherein the geometry of the alignment of at least one section () of the at least one channel () is designed such that the coolant flows in the direction of the axle () of the shaft () through the at least one channel (), having a deviation of less than 40°. 15. An electrical machine () , comprising{'b': '9', 'a housing (),'}{'b': 8', '30, 'a shaft () having a axis (),'}{'b': 6', '7, 'a stator () and a rotor (),'}{'b': 11', '5', '12', '11', '11', '30', '8, 'at least one channel () for conducting a cooling fluid for cooling the electrical machine (), characterized in that the geometry or the orientation of at least one section () of the at least one channel () is designed to the effect that the cooling fluid flows through the at least one channel () with a deviation of less than 40° in the direction of the axis () of the shaft ().'}2111312111516. The electrical machine as claimed in claim 1 , characterized in that the geometry or the orientation of the at least one channel () is designed to the effect that claim 1 , in at least a first pair () of two sections () of the at least one channel () claim 1 , the cooling fluid in an A section () flows in the opposite direction to a B section ().3151611. The electrical machine as claimed in claim 2 , characterized in that a component stream of cooling fluid is in each case conducted though the A section () and through the B section () of the at least one channel ().4. The electrical machine as claimed in claim 3 , characterized in that the two component streams are substantially identical.5111516265275. The electrical machine as claimed in claim 2 , characterized in that the geometry or the orientation of the at least one channel () is designed to the effect that the cooling fluid in the A ...
