Abstract
A stator of an electric machine includes a stator lamination package including a plurality of stator laminations and a coolant guide arranged between the stator laminations. The stator laminations include radially inward recesses and stator windings are arranged in the stator grooves, directly around which windings a coolant can flow within the stator grooves. The coolant guide includes first lamination blanks axially bordering the coolant guide on opposite sides thereof. The coolant guide includes second lamination blanks arranged between the first lamination blanks. The first and second lamination blanks and the stator laminations radially include recesses. Only the second lamination blanks additionally include radial coolant channels configured to guide coolant radially inward or radially outward. The radially inward recesses of the stator laminations and the lamination blanks are closed in a radially inward direction, and axially adjacent stator laminations and lamination blanks are glued together in a laminar manner.
