Abstract
A stator (1) for an electric motor, which comprises a substantially hollow-cylindrical stator stack (2) provided with wire windings and an end winding (6), which adjoins the stator stack (2) in the axial direction, wherein the stator stack (2) comprises a number of slots (4), wherein a coolant line (8) is inserted into the respective slot (4), is intended to enable a further improvement of the efficiency of the electric motor. For this purpose, a section (10) of the respective coolant line (8) extends into the region of the end winding (6).
