Abstract
A method for manufacturing an armature including securing a core to the shaft having a plurality of slots extending in the axial direction formed on the outer circumferential surface thereof, forming a coil composed of a plurality of coil portions by simultaneously winding wires a plurality of turns around a pair of slots separated by a predetermined number of slots and offsetting each of the coil portions one slot at a time in the circumferential direction of the core, securing a commutator to the shaft having a plurality of segments, adjacent coil portions having a slot along one side thereof, and electrically connecting segments which should have the same electric potential by means of equalizing connectors so that each pairs of the segments that should have the same electric potential has a substantially equal electrical potential.
