Claims

[Claims for Utility Model Registration] Three ring-shaped cores each having a plurality of teeth equally spaced along the circumferential direction are formed on the inner wall surface, and these three ring-shaped cores are electrically shifted by 120 degrees. On the other hand, two ring-shaped coils are interposed between the above three ring-shaped cores so that they are coaxial with this core, and these two ring-shaped coils are An armature for an alternating current machine, characterized in that it is connected to a three-phase power supply by V-connection, and the outer walls of the three ring-shaped iron cores are connected to each other by a yoke.
