Abstract
In a direct-current motor armaturecorresponding to an 8-pole-10-slot-20-segment or 12-pole-15-slot-30-segment, a connection wirefor short-circuiting segmentshaving the same degree of electric potential is provided to a commutator, a coilis connected electrically to the segmentshaving a potential difference that is equal to a potential difference between the adjacent segments, and the coilis wound around teethto form armature coils. Accordingly, an armature for use in a direct-current motor, a direct-current motor, and a method for winding wires around the armature of the direct-current motor for enabling down-sized direct-current motors having extended product life and enhanced performance can be provided.
