A rotor assembly for a dynamo electric machine, the rotor assembly comprising a rotor core incorporating radially extending rotor poles, rotor windings encircling respective rotor poles, circumferentially extending pole tips at the outer end of each pole respectively, said tips overlying the rotor winding encircling the respective pole, a plurality of rotor slot closure members, each closure member spanning the gap between a pair of adjacent poles, and including lateral flanges interposed between the respective rotor windings and the associated pole tips, a spacer member positioned beneath each closure member and engaging the radially extending faces of the adjacent windings, and, a locking wedge assembly comprising a pair of locking wedges extending axially of the rotor assembly between each closure member and the associated spacer, the locking wedges extending with their tapers in opposite directions so that moving the wedges longitudinally towards one another increases the radial dimension of the combination of the locking wedges driving the associated spacer and closure apart in a radial direction. Also disclosed is a method of manufacturing a rotor assembly.
