Abstract:
A stator (1) for an electric machine (100) has stator laminations (3) stacked in an axial direction (A) to form a stator lamination stack (2). The stator laminations (3) have strip-shaped inserts (4) extending in a radial direction (R). The inserts (4) have a higher thermal conductivity than the rest of the stator lamination (3). The stator laminations (3) are rotated in relation to one another in an azimuthal direction (U) about an angle of rotation (D) in such a manner that the inserts (4) of directly adjacent stator laminations (3) are not arranged one above another in the axial direction (A). An electric machine (100), a motor vehicle (200) and a method for producing a stator (1) also are provided.
