Abstract

PURPOSE:To concentrate the insulating part to one plate to perform sure insulation and to facilitate quality control in the midst of assembling work to enhance reliability of an electic rotary machine by a method wherein insulation for prevention of shaft current is performed at the connecting part of the rotary shaft and thrust collars. CONSTITUTION:A ring type insulating ring 4 is arranged at the connecting part of the thrust collars 8a, 8b of a thrust bearing being supported by an upper part guide bearing 10 and a thrust rest plate 14 and the rotary shaft 1 contriving to prevent the shaft current. Accordingly because interception of a shaft current circuit can be performed at one place, sure insulation and simplification of assembling work can be attained.
