Summary:PROBLEM TO BE SOLVED: To provide a stator coil capable of reducing an axial height of a coil end while keeping insulation between segment conductors neighboring to each other.SOLUTION: The segment conductor is disposed between slots of a stator to which AC currents of multiple phases are supplied. The segment conductor in a coil end part axially protruding from the stator is formed with such a dimension that the thickness is equal to or less than one out of the number of phases of AC currents supplied to the stator relatively to thickness of a segment conductor disposed within the stator.SELECTED DRAWING: Figure 1 【課題】隣り合うセグメント導体間の絶縁性を確保しつつ、コイルエンドの軸方向高さを短縮可能なステータ巻線を提供する。【解決手段】複数相の交流電流が供給されるステータのスロット間に配置されるセグメント導体であって、ステータから軸方向に突出したコイルエンド部のセグメント導体の厚みは、ステータ内部に配置されたセグメント導体の厚みの、ステータに供給される交流電流の相数分の一以下の寸法で形成される。【選択図】図１
