Abstract
A three-phase alternating-current winding is configured by connecting first conductor terminals and second conductor terminals that are disposed in a circular arc-shaped region using connecting units, electric power supplying terminals of the three-phase alternating-current winding are constituted by the first conductor terminals and the second conductor terminals that are disposed in the circular arc-shaped region, a number of parallel phase windings in the three-phase alternating-current winding is n, where n is a natural number that is greater than or equal to one, an angular range of the circular arc-shaped region is less than or equal to (180×n) electrical degrees, and the second conductor terminals that constitute the electric power supplying terminals are positioned between adjacent first conductor terminals when viewed from a radially outer side.
