ABSTRACT:
A D.C. rotary electric machine comprises an armature winding having a plurality of unit coils shifted from each other by a predetermined electrical angle and a commutator having a plurality of commutator segments. Each unit coil includes a pair of coil sides and is connected between two commutator segments. The unit coils are positioned with respect to the commutator segments so that an axial line passing through the midpoint between the pair of coil sides of each unit coil is circumferentially advanced by a predetermined angle with respect to an axial line passing through the midpoint between the commutator segments to which the coil unit is connected.
