Abstract

A method of manufacturing a rotor of an electric motor or an electric generator includes positioning a plurality of amortisseur bars (120) and using additive manufacturing to place electrically conductive material (116). More specifically, positioning the amortisseur bars may include circumferentially positioning the bars around a rotor stack (110) and using additive manufacturing to place electrically conductive material may include forming a non-solid pattern of electrically conductive material, such as a pattern of electrically conductive traces (333), across opposite axial ends of the rotor stack to electrically interconnect an amortisseur circuit.
