Patent ID: 8076819

Claim:
A rotary machine stator comprising: a stator core in a cylindrical shape, the stator core including a slot and a slot opening between top edges; an insulating film formed in a cylindrical shape to be in close contact with an inner surface of the slot, the insulating film including a gate on both ends in a circumferential direction that is bent inside to form a film opening having a width equal to or larger than a width of the slot opening, the insulating film configured to be inserted in the slot such that a film axial direction end of the insulating film protrudes from an axial direction end of the stator core; and an insulator in a ring shape attached to both ends of the stator core in an axial direction, the insulator including an insulator slot and an insulator opening between insulator edges formed to be substantially identical in shape with the slot and the slot opening between the top edges of the stator core, respectively, the insulator edges provided with a lock on a side of the insulator slot to insert and lock the film axial direction end near the gate of the insulating film.
