Abstract

PURPOSE: To enable even a thin wire to be reliably connected to a commutator segment through tig welding, by forming the weld-section of the commutator segment to have a large weld-area.
CONSTITUTION: In a commutation device of a rotary electric machine having commutator segments to which armature windings are connected by welding, the weld-surface 4 of a commutater segment 1 is inclined by an angle θ to increase the weld-area. Thus, an armature winding consiting of a thin wire can reliably be connected to a commutator segment by means of tig welding.
