Armature, armature manufacturing method, and rotating electrical device

An armature comprising:

• a plurality of core configuration members that configure an armature core and are divided in a circumferential direction of the armature core;
• a plurality of insulators that each include a pair of insulation portions integrated with the core configuration members and a coupling portion that couples the pair of insulation portions together;
• and
• a plurality of coil wires that each include a pair of wound portions that have been wound onto the respective core configuration member with the insulation portions interposed between the core configuration members and the wound portions, and a crossing wire that connects together the pair of wound portions;
• wherein:
• a plurality of armature configuration units are configured independently of each other by integrating a pair of the core configuration members with each of the plurality of insulators and winding the respective coil wire onto the pair of core configuration members,
• assuming that a number of the plurality of core configuration members is n, in each of the plurality of armature configuration units, one of the core configuration members is disposed with respect to the other of the core configuration members at a mechanical angle in a range of (360°/n)×2 or greater and less than 180°, and
• in the armature configuration units that configure the same phase out of the plurality of armature configuration units, the coupling portion and the crossing wire of one of the armature configuration units are arranged side by side with the coupling portion and the crossing wire of the other of the armature configuration units along a direction orthogonal to an axial direction of the plurality of armature configuration units.
