Abstract:
Phase insulation for separating conductors conducting different phases at an end of a stator core of a multi-phase dynamoelectric machine, comprising:a strip of dielectric material connected to form a cylinder with a top edge, a bottom edge and a side wall, the cylinder having a full diameter and at least one opening in the side wall extending through the bottom edge and extending toward the top edge, and a corresponding continuous portion between said at least one opening and the top edge, said continuous portion folding when the cylinder is compressed radially, said at least one opening defining a radial compression area;wherein the cylinder is compressed radially, and the continuous portion folds, and the radial compression area compresses to form a compressed cylinder having a compressed diameter which is less than the fall diameter, the compressed cylinder electrically separating windings conducting said different phases.
