Summary:To provide a stator manufacturing apparatus that can prevent a gap between a plurality of laminated steel sheets from opening in the axial direction during energization heating in a stator in which a cuff support is abolished.SOLUTION: A stator core 10 in which a plurality of segment coils 20 and foamable insulators 30 are inserted into a plurality of slots 11 is installed on an installation base 50. Support members 60, 610, and 620 support a radially inner end portion 15 of a teeth 14 of the stator core 10 from the axial direction of the stator core 10 in such a manner that a gap does not occur between a plurality of laminated steel sheets 12 constituting the stator core 10. An energization heating device 80 heats the foamable insulator 30 together with the plurality of segment coils 20 by energizing the segment coils 20, to thereby foam the foamable insulator 30.SELECTED DRAWING: Figure 14 【課題】カフサを廃止したステータにおいて、通電加熱時に複数の積層鋼板同士の間が軸方向に開くことを防ぐことの可能なステータの製造装置を提供する。【解決手段】設置台50は、複数のセグメントコイル20および発泡インシュレータ30が複数のスロット11に挿入されたステータコア10が設置される。支持部材60、610、620は、ステータコア10が有するティース14の径方向内側の端部15を、ステータコア10を構成する複数の積層鋼板12同士の間に隙間が生じないようにステータコア10の軸方向から支持する。通電加熱装置80は、複数のセグメントコイル20に通電することでセグメントコイル20と共に発泡インシュレータ30を加熱し、発泡インシュレータ30を発泡させる。【選択図】図14
