Verfahren und Einrichtung zur Herstellung des Staendergehaeuses von elektrischen Maschinen

摘要

The manufacture of the stator core frame of a large electrical machine and more particularly turbogenerators in which the stator core frame is set vertically, fastened in such position and then slotted by a machining operation, for example by milling. The stacking ribs are fitted into the slots, after which the frame is unfastened and set horizontally. The stacking ribs are welded into the slots, and the frame is again set vertically and fastened. At least one seating surface of the stacking ribs is finally machined, preferably by milling.
