Abstract
A V-block assembly for an electrical machine having a rotor with a spider and poles disposed in a circular array around the spider and conductive windings encircling the poles comprising a dovetail groove in the spider between adjacent poles and a plurality of V-blocks each comprising a pair of flat bars having one end abutting, the abutting end being formed to fit the dovetail, the flat bars being bent outwardly to form a V and a jack screw fastened between the flat bars adjacent the open end to press the bars against the windings of adjacent poles to prevent the windings from moving laterally and radially outward as the rotor rotates.
