Zusammenfassung: | To provide a stator structure in a rotary electric machine which can reduce the AC loss of the coil of a stator.SOLUTION: The stator structure in a rotary electric machine according to an embodiment includes an inside coil layer and an outside coil layer. In the inside coil layer, a plurality of coreless inside coils are arranged in a circumferential direction. In the outside coil layer, a plurality of coreless outside coils are arranged in a circumferential direction on the outside of the inside coil layers separately from the inside coils. The coil windings of the inside coils are formed of materials different from those of the coil windings of the outside coils.SELECTED DRAWING: Figure 2
【課題】固定子のコイルでの交流損失を低減可能な回転電機における固定子構造を提供すること。【解決手段】実施形態では、回転電機における固定子構造は、内側コイル層及び外側コイル層を備える。内側コイル層では、コアレスの複数の内側コイルが周方向に並んで配置される。外側コイル層では、内側コイル層の外周側に内側コイルと接触しない状態で、コアレスの複数の外側コイルが周方向に並んで配置される。内側コイルのそれぞれのコイル巻線は、外側コイルのそれぞれのコイル巻線とは異なる材料から形成される。【選択図】 図2 |
