ABSTRACT OF THE DISCLOSURE A dynamoelectric machine, having a laminated stator core and having low impedance short-circuiting rings positioned between end flanges to minimize voltage difference between key bars. Circumferentially spaced key bars are used to effect assembly of the laminations and the end flanges. Circumferentially aligned recesses are formed in the key bars spaced inwardly from the end flanges, and each short-circuiting ring is positioned within aligned recesses. The short-circuiting rings comprise a plurality of arcuate ring segments and are formed of a material of high conductivity. Bolts secure the segments to the key bars.
