Abstract
1284928 Commutation of dynamoelectric machines WESTINGHOUSE ELECTRIC CORP 15 Oct 1969 [5 Nov 1968] 50662/69 Heading H2A In a dynamoelectric machine cylindrical commutator comprising a plurality of mutually insulated bars 22 secured to a supporting bushing 30, such bars are tightly clamped together by a plurality of bands 36 disposed in recesses 34 in the bar cylindrical radially outer surface 26 at spaced locations along the commutator axis, and to reduce the arching pressure and thereby use smaller bands each bar has in its radially inner surface between two bands at least one recess 24 extending parallel with such axis. The bands may be of cured resin, impregnated glass tape or laminate, and there are provided an insulating sleeve 28 and risers 37.
