Abstract

1328965 Improving commutations of dynamoelectric machines NATIONAL RESEARCH DEVELOPMENT CORP 8 Oct 1970 [7 Nov 1969] 54686/69 Heading H2A The invention is similar to that disclosed in Specification 1,328,781 which is referred to, but differs principally in that diodes D 1 , D 2 are used instead of thyristors, and resistors R 1 , R 2 , and R 3 , R 4 are serially connected with at least two brushes 13, 15, or 23, 25 of each set.
