ABSTRACT:
A pole change dynamo-electric machine with three-phase distributed winding is adapted for reconnection to form either one of two different pole numbers and for operation on either one of two different voltages. The adjacent coils of the winding are divided into N coil groups, N being equal to three times the greater one of the pole numbers. Every twelve adjacent coil groups form a set of coil groups. The beginning and end terminals of the specific coil groups within each set are connected and the rest of the terminals are reconnectable.
