发明名称 AIR-COOLED ELECTRIC MACHINE HAVING COOLING RIBS FORMED FROM STATOR SHEET
摘要 An electric machine has rotor rotatably supported in bearings for rotation about an axis of rotation, a stator surrounding the rotor with respect to the axis of rotation and having stator sheets, which are stacked in the direction of the axis of rotation. The stator sheets have a number of recesses which form grooves extending parallel to the axis of rotation. Tension strips are arranged in the grooves and connected to end rings. The stator sheets include at least first stator sheets. The first stator sheets each have at least one large lug. Between the two tension strips adjacent to the respective large lug in a circumferential direction about the axis of rotation, the large lug protrudes radially outward beyond the two adjacent tension strips. The large lug has cantilevers extending about the axis of rotation and reaching over the two adjacent tension strips.
