ABSTRACT:
An electric machine stator comprises a core with slots for placing winding bars therein. The winding bars are locked within the slots by pairs of oppositely directed wedges. To eliminate the possibility of an axial displacement of the wedges and, as a result, a looseness of wedging the winding bars, the peripheral portions of extreme wedges adjoining the winding bars protrude outside the stator core and have cross slots with a band located therein which also surround the stator winding bars.
