ABSTRACT:
A series coupling synchronous axial gap type motor where rotors and stators are alternately stacked with required air gaps in the axial direction of a rotary shaft as a main shaft, is provided. The rotors are fixed to the rotary shaft, and the stators are disposed such that they cannot be interlocked with the rotary shaft. A plurality of rotary field bodies are attached to each of the rotor around the axis, and a plurality of armature coils are made to face the rotary field bodies with an air gap therefrom and are attached to each of the stators around the axis such that their magnetic-flux directions are directed toward the axial direction. The armature coils have an empty core, or a core member composed of a magnetic body attached thereto.
