ABSTRACT:
A winding is provided for dynamoelectric machines having a plurality of pole groups disposed to form a poly-phase winding. Each pole group consists of a number of multi-turn coils divided into two subgroups with the coils of one subgroup having one more turn than the coils of the other subgroup. Field strengths can thus be obtained equivalent to what could be produced by coils having fractional numbers of turns intermediate between the actual numbers of turns of the coils of the two subgroups, the effective number of turns being determined by the relative number of coils in the two subgroups of each pole group.
