PROBLEM TO BE SOLVED: To provide a stator for a dynamo-electric machine which will not induce cavities due to resin unimpregnation at its axial center, where proper performing of the impregnation of resin is carried out, even if the stator core is long in the axial direction. SOLUTION: The stator core 13 is constituted by stacking first blanked plates 15, having slots in its axial direction and interposing second blanked plates 16 that have slots with dimensions larger than those of the slots of the first blanked plates 15, in the axial intermediate section of the stack by the first blanked plates 15. The stator coil 14 is mounted in the slot of the stator core 13. The stator core 13 and the stator coil 14 are immersed in a resin impregnation container 20, thereby being impregnated with resin 19, whereby not only both the axial ends of the stator core 13, but also the slot of the stator core 13 are impregnated with resin through the slots of the second blanked plates 16 having large slot dimensions. Then, the stator core 13 and the stator coil 14 are removed from the resin impregnation container 20 and the resin is made to harden. COPYRIGHT: (C)2006,JPO&NCIPI
