Abstract
A stator winding includes: a plurality of stator bars and a connection structure. Each of the stator bars penetrates each of the stator slots and includes at least one hollow element wire, wherein inside the at least one hollow element wire a flow hole for a cooling medium is formed. A connection structure includes: a sleeve whose axial one end is fitted to a vicinity of an end of the stator bar; a closing plate disposed at another end of the sleeve; and a hollow extension pipe. The hollow extension pipe is disposed in a space defined by the sleeve and the closing plate at the end of the stator bar, and makes the flow hole of the hollow element wire and an outside of the space communicate each other. A brazing material is filled in the space.
