ABSTRACT:
A plurality of winding units each composed of a wire element are serially arranged in the axial direction of the winding between an inner insulating sleeve and an outer insulating sleeve, and vertical cooling paths are formed on opposite sides of each winding unit and horizontal cooling paths are formed between adjacent winding units. The winding units are divided into a plurality of winding sub-units to define a central vertical cooling path therebetween, which central vertical cooling path includes a via flow path and a branch inducing flow path, whereby cooling fluid flows in opposite directions and at substantially the same speed in the horizontal cooling paths along upper and lower surfaces of each of the winding units having the branch inducing flow path. In this manner, the entire winding is uniformly cooled.
