Abstract
The invention provides a coil member of rotating electrical machinery, by which improvements in the mass production and downsizing thereof are enabled, which is a coil assembly for rotating electrical machinery, consisting of a plurality of coil combinations mounted at iron core slots, wherein the respective coil combinations 14 are inserted into slots at pitches equivalent to an appointed number of slots, and are formed of an integral coil member 21 in which the first and the second linear portions 21A and 21B alternately disposed at the inner layer side and the outer layer side in the slots, and the first and the second turning portions 21C and 21D for connecting the first and second linear portions 21A and 21B adjacent to each other outward of one end side and outward of the other end side in the lengthwise direction of the slots are integrated together. And, the first linear portion 21A of the appointed coil member 211 thereof, and the second linear portion 21B of another coil member 211 are laminated and disposed in the same slots.
