Abstract
A generator rotor pole crossover including a substantially U-shaped portion from which extend legs curving outwardly. The U-shaped portion is thickened in one direction but thinned in another direction, relative to the leg thickness. This configuration provides flexibility to the crossover, decreased stress and relatively constant cross section of resistance purposes. The legs are brazed to the copper conductor winding ends by scarf and lap joints, respectively. The crossover may replace defective crossovers in the field by removing only the end plate of the generator. This allows installation in a short time without risk of damage to generator insulation.
