<p>PURPOSE:To increase reliability of insulation and mechanical strength of of windings and at the same time to achieve low noise by connecting at least one side end of a plate-like insulating member to the wall of an insulating cylinder and connecting the connected end side to the wall surface with the end side bent downward in the vicinity of the insulating cylinder to form a groove space between the end side and the wall surface. CONSTITUTION:A rail for forming a duct is fixed along the respective axial directions of the outer side of a base insulating cylinder 2 located outside a winding disposed around an iron core and a base insulating cylinder 1 located inside an inner side winding, and a conductor with an insulating material is wound to form a winding. A closed plug 4 which is a plate-like insulating member of which one side end is connected to the insulating cylinders 1, 2 with respect to the outside and the inside of the radial direction of the winding, is disposed in the winding for every several sections. The vicinity of the outside insulating cylinder 1 and the inside insulating cylinder 2 of the closed plug 4 is bent downward, and a groove 5 is formed in the circumferential direction of the closed plug 4.</p> |
