Abstract
A stator winding includes a plurality of first to sixth winding sub-portions each having one turn. First series-connected windings are formed with the first, third, and fifth winding sub-portions connected in series. Second series-connected windings are formed with the second, fourth, and sixth winding sub-portions connected in series. Each of Winding phase groups for each phase is formed with the first and second series-connected windings connected in parallel.
