ABSTRACT:
A method of locking coiled conductors in slots of a dynamoelectric machine rotor by placing deformable locking members over selected axially limited areas of the coiled conductors and driving the ends of the locking members under tips of salient rotor poles to secure the locking members firmly in position against the outer surfaces of the conductors. In one form of the invention preformed sheets of insulating material are positioned around the coiled conductors and under the deformable locking members to insulate the coils from the sides of the rotor poles and from the locking members. An aspect of the invention includes the combination in a dynamoelectric machine rotor of a plurality of deformable locking members positioned to secure coiled conductors in rotor slots and to secure preformed sheets of insulating material between the outer surfaces of the conductors and the locking members when they are arranged in their coil-locking positions.
