Abstract: A hybrid-electric propulsion system is provided. In one example aspect, the hybrid-electric propulsion system includes a power converter and a propulsor. The propulsor includes a gas turbine engine having a shaft and one or more bearings supporting the shaft. The propulsor also includes an electric machine electrically coupled with the power converter. The electric machine includes a stator assembly and a rotor assembly. The rotor assembly has a rotor and a rotor connection assembly. The rotor connection assembly operatively couples the rotor with the shaft. The rotor connection assembly has an insulated joint for interrupting common mode electric current from flowing from the rotor of the electric machine to the shaft. A grounding device is included to electrically ground the shaft. The power converter includes an electromagnetic interference filter to reduce common mode voltage reaching the electric machine.

Abstract: A propulsion assembly includes a first torque source coupled with a first shaft and a second torque source coupled with a second shaft. A coupler selectively couples the first and second torque sources. When the first and second torque sources are coupled via the coupler, in response to a command to decouple the first torque source, an unloading operation is performed to decrease the torque output provided by the first torque source to a threshold, and when reached, the first shaft is decoupled from the coupler. When the first torque source is coupled with the coupler but the second torque source is not, in response to a command to couple the second torque source, a speed matching operation is performed to increase the speed of the second shaft to match a speed of the first shaft, and when the speeds are matched, the second shaft is coupled to the coupler.

Abstract: A system for laterally moving an industrial machine is provided. The system includes a pair of rail elements configured to be positioned laterally below and support the industrial machine, the rail elements allowing the industrial machine to be moved laterally from a first operative position to a second, maintenance position; and a pair of linear actuators configured to laterally move the industrial machine as from the first, operative position to the second, maintenance position. The rail elements may include a first skid configured to couple laterally to an underside of the industrial machine at a first axial position; and a second skid configured to couple laterally to an underside of the industrial machine at a second axial position. First and second segmented support rails are positioned in sliding, aligned contact with the first and second skid, respectively, and are configured to be supported on a respective machine foundation.

Abstract: An electric component for an electric machine includes a body having slots defined therein, and a conductive winding extending out of axial end(s) of the slot(s). The electric component may include any electric machine component having conductive windings, e.g., a stator for a generator. The electric component includes a resin dam around the conductive winding at axial end(s) of the slot(s). The resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot(s), during manufacture. The electric component also includes a (solidified) insulating resin in the slot(s) and against the resin dam(s) at the axial end(s) of the slot(s). Any number of the conductive windings and slots may include a resin dam, e.g., one, some or all. The resin dams ensure complete filling of the slots and encapsulation of the conductive windings.
