  • Stator with a cooling jacket, electric machine and motor vehicle
    Patent number: 11817744
    Abstract: A stator for an electric machine of a motor vehicle includes a laminated core having an inner side with winding grooves and an outer side. Windings, which are arranged in the winding grooves, form winding heads on axially opposing front faces of the laminated core. A cooling jacket conducts cooling fluid and has a first metal sheet which forms an inner wall of the cooling jacket facing the laminated core, and a second metal sheet which forms an outer wall of the cooling jacket surrounding the inner wall. An axial height of the cooling jacket exceeds an axial height of the laminated core. The cooling jacket has a laminated-core cooling jacket region for encasing the laminated core and two axially opposing winding-head cooling jacket regions adjoining the laminated-core cooling jacket region for encasing the winding heads.
