Abstract
A stator is configured so as to have an annular shape by linking core blocks that are each produced by laminating electromagnetic steel sheets and that each have a yoke portion and a tooth portion by bendable first linking portion, concentrated winding coils are each produced by winding a conductor wire around the tooth portion for a number of turns so as to pass through concave spaces that are formed by the trunk portions and first and second guiding portions of first and second insulating bobbins, and current-carrying member holding portions that hold first current-carrying members that configure the concentrated winding coils into alternating-current connections are constituted by holding grooves that are each formed so as to open radially outward and so as to pass through the first guiding portions circumferentially, and that are arranged in three layers in an axial direction.
