Zusammenfassung:To provide a stator structure in a rotary electric machine which can increase the amount of interlinkage magnetic fluxes which are interlinked with a coreless coil in a generated rotary magnetic field.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 layer separately from the inside coils. The coil pitches of each inside coil and each outside coil are at least the angle of dividing 360° by the total number of the inside coils and the outside coils.SELECTED DRAWING: Figure 2 【課題】発生する回転磁界においてコアレスのコイルと鎖交する鎖交磁束量を増加させることが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。内側コイル及び外側コイルのそれぞれのコイルピッチは、360°を内側コイル及び外側コイルの総数で除算した角度以上となる。【選択図】 図2
