Abstract
The present disclosure provides an armature of a rotating electric machine. The armature of the rotating electric machine includes a wedge that is configured to close an opening of a slot around which coils are wound and support the coils disposed to a left side and a right side of the slot to prevent the coils from seceding from a core. The wedge includes a main plate that has a substantially V-shaped section. In addition, a support plate of the wedge is coupled with the main plate within the main plate and is configured to support the main plate in directions in which the main plate spreads to maintain a shape of the main plate.
