Abstract:
1. A series coupling synchronous axial gap type motor, comprising: a rotary shaft as a main shaft, and rotors and stators alternately stacked with required air gaps in the axial direction of the rotary shaft, wherein the rotors are fixed to the rotary shaft, the stators are disposed not to be interlocked with the rotary shaft, a plurality of rotary field bodies are attached to each of the rotor around the axis, 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, the air gap between the rotary field bodies and the armature coils is set to 0.1 mm to 1 mm; and wherein the stators are provided with axial through-holes, the armature coils are fixedly fitted into the through-holes, and both ends of the armature coils are made to project from both end faces of a stator, and are made to face the rotary field bodies fixed to the rotors on both sides of the stator.
