More Information
Summary:An electric drive assembly comprises a housing, an electric machine with a stator and a rotor, the stator having a stator core and winding heads, the rotor being connected to a rotor shaft, which is rotatably mounted in the housing about an axis of rotation, a transmission rotationally drivable by the rotor shaft, at least one fluid distribution element for supplying coolant to one of the winding heads, wherein the fluid distribution element at least partially covers an upper part of the winding head in the circumferential direction and in the axial direction and has a guide structure with a gradient in the circumferential direction, so that coolant supplied to the fluid distribution element from above is distributed in the circumferential direction and runs onto the winding head in several angular positions over a circumferential area of at least 30° with respect to the axis of rotation.
