Abstract

The object of the invention is to provide an armature which is in good rotational balance, where the total number of the coils to be disposed in the slots of the rotary electric machine can be freely set when winding coils on the armature core. Coils are wound on an outer periphery of an armature coreby use of a winding devicewhich is provided with sixteen nozzlesmovable in the axial direction to draw out the coils to thirty two slots formed on the outer periphery of the armature core, wherein sixteen coilsare simultaneously wound through a single winding operation and the winding operation with respect to the slotis performed three times in such a manner that the total number of the coilsin the slotsbecomes 96 (C) so that the number obtained by dividing the total number of the coilsC by twice the number of the slots does not become a natural number.
