Abstract

1502321 Dynamo-electric machines COMPAGNIE ELECTRO MECANIQUE 30 Jan 1975 [31 Jan 1974] 4156/75 Addition to 1441161 Heading H2A The electric machine described with reference to Figs. 15 and 16 of the parent Specification is modified in that the coil groups A4, B4, C4 are connected permanently in parallel with coil groups A1, B1, C1 respectively. The coils in the groups will be changed relative to the machine of the parent Specification in order to provide a balanced winding for both pole numbers.
