Abstract: A rotor pack for a generator has an exciter rotor rotating with a shaft. A rectifier assembly is in electric communication with the exciter rotor to receive AC current and rectify the AC current into a DC voltage. Positive and negative busses extend from the rectifier assembly to a negative rail and a positive rail on a connection assembly. The negative rail is in contact with the shaft to provide a ground connection. The negative and positive rails are formed of a metal. The negative and positive rails are connected to a main field winding. A high speed generator is also disclosed.

Abstract: A method of manufacturing a rotor of an electric motor or an electric generator includes positioning a plurality of amortisseur bars and using additive manufacturing to place electrically conductive material. More specifically, positioning the amortisseur bars may include circumferentially positioning the bars around a rotor stack 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, across opposite axial ends of the rotor stack to electrically interconnect an amortisseur circuit.

Abstract: A generator arrangement includes a stator with armature winding, a rotor with one or more permanent magnets supported for rotation relative to the stator, a variable speed drive, and a control module. The variable speed drive is connected to the rotor for rotating the rotor within a predetermined speed range. The control module is disposed in communication with the armature windings and is operatively connected to the variable speed drive to maintain constant output voltage as load changes by varying rotational speed of the rotor.

Abstract: A rotor for an electrical machine includes a rotor core having a plurality of circumferentially spaced apart rotor poles. Windings are seated in gaps between circumferentially adjacent pairs of the rotor poles. A wedge secures the windings in each gap. The wedge includes a first member made of a first material and at least one second member made of a second material. The second material has a higher electrical conductivity than the first material. The wedge is configured to supply Q-axis damping. A pair of end plates is connected electrically to the at least one second member at opposing longitudinal ends thereof thereby completing a Q-axis winding circuit for each wedge.
