Abstract
A stator of a rotating electrical machine that can realize productivity growth, compared with a conventional technique is provided. A stator of a rotating electrical machine includes a slot; a plurality of coils disposed within the slot; and an insulator disposed around the coils within the slot. The insulator has an outer peripheral portion that surrounds the plurality of coils; and a bent portion that extends from the outer peripheral portion between the coils and that is folded back on a tip end.
Claims5
A stator of a rotating electrical machine comprising:
- a slot;
- a plurality of coils disposed within the slot in an arrangement in which the coils are stacked in an axial direction of the stator;
- and
- an insulator disposed around the coils within the slot, wherein
- the insulator has an outer peripheral portion that surrounds the plurality of coils;
- the insulator has two bent portions, each of which extends from the outer peripheral portion between adjacent coils of the plurality of coils, is folded back on itself, and has a tip end, and
- the tip ends of the two bent portions face each other with a gap provided between the tip ends in a central area of the coils in a circumferential direction of the stator.
