DYNAMOELECTRIC MACHINE COMPRISING WEDGED WINDING BARS

摘要

The invention relates to a dynamoelectric machine (20) comprising winding bars (13) which are inserted into grooves provided therefor and pertaining to the dynamoelectric machine (20). Said grooves are respectively closed by closing wedges (23) and sinuous springs (16) are provided between the closing wedges (23) and the winding bars (13) located beneath, said springs being pre-tensioned by means of counter-wedges (21) which are arranged between the closing wedges (23) and the winding bars (13) located beneath. One such machine enables wedging to be carried out in a fast and simple manner, due to the fact that the counter-wedges (21) are arranged between the closing wedges (23) and the sinuous springs (16), and that fixed adjustment elements (22) are provided, by which means the distance between the closing wedges (23) and the counter-wedges (21) can be changed.
