ABSTRACT:
A flat armature is manufactured by forming a given number of coils over a separatable winding frame, fixing their relative positions by putting adhesive tapes across the coils on the frame, removing the coils from the frame, arranging a group of coils on a plane so that it will form a ring configuration, equipping the coils with a commutator, and moulding the coils equipped with the commutator with resin.
