ABSTRACT:
A multiturn coil assembly with direct water cooling, for use in dynamoelectric machine field poles, has several horizontal layers of turns and several vertical rows of turns, and includes three individual windings formed from hollow copper conductors of rectangular cross section, the windings being concentrically arranged and electrically connected in series. Each winding occupies a single vertical row, has an equal number of turns wound in the same direction and is arranged so that the terminals of all the windings positioned adjacent one another on end surfaces of the coil extend along one side of the coil. All winding terminals are connected by brazing on one of the outer coil sides, which decreases both the coil height and the number of brazed joints, and ensures easy access to the joints for inspection and maintenance.
