The invention discloses an asymptotical equalizing wire structure which comprises the components of two armature coils, an armature clamping ring which is arranged at the radial inside of a non-commutator connecting end of the two armature coils, an equalizing spool which is arranged at the radial inside of the armature clamping ring, and an insulated pressure board which is arranged at the axial side of the equalizing spool. Two equalizing wires are sandwiches between the equalizing spool and the insulated pressure board. An insulated gasket is arranged between the two equalizing wires. An insulating plate is arranged between the equalizing spool and the adjacent equalizing wires. The equalizing wires are connected with the armature coils through an end joining sleeve. The asymptotical equalizing wire structure is mounted on the non-commutator end for settling the problems of complicated original structure, inconvenient manufacture and inconvenient maintenance.
