ABSTRACT:
A method for winding coils on an armature for miniature motor which typically comprise an armature iron core of a multi-pole construction, having a plurality of coils wound thereon, a commutator disposed on an insulating cylinder fixedly fitted to a motor shaft, and ends of lead wires drawn from the coil connected to commutator tongues of the commutator, in which a plurality of coils are wound sequentially on the armature iron core, and the trailing end of the lead wire drawn from the lastly wound coil is connected to a predetermined commutator tongue after the lead wire is wound on the insulating cylinder at a predetermined angle in such a manner that the lead wire intersects and makes contact with all the lead wires lying between the already wound coils and the commutator tongues at least more than once.
