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 variable coaxial shaft for a hydraulic unit includes a shaft body having a variable input shaft interface to drive rotation of a variable input shaft of the hydraulic unit. The variable coaxial shaft also includes a differential assembly interface having a first sealing interface, a second sealing interface, and one or more lubrication ports between the first sealing interface and the second sealing interface. The differential assembly interface is configured to be driven by a differential assembly. The one or more lubrication ports provide a lubrication path to the differential assembly. A shaft length is defined between a first end of the variable input shaft interface and a second end of the differential assembly interface. A ratio of the shaft length to a shaft diameter of the shaft body is between 18.65 and 19.12.

Abstract: A method of installing the terminal block assembly onto a generator includes the step of providing a terminal block with multiple terminal studs. Protrusions that are integral with the terminal block are aligned with corresponding bores in a generator housing. The terminal block is mounted on the generator housing with the protrusions received in the bores. A terminal lead assembly is inserted through the protrusion, and a terminal pad of the terminal lead assembly is arranged over the terminal stud. A terminal lug is fastened to the terminal stud. A terminal cover is secured to the terminal block over the terminal with a boss of the terminal block received in a corresponding recess of the terminal cover.

Abstract: A method includes pumping coolant into a cooling system of a generator while the generator is generating electrical power. The method includes regulating flow into the cooling system using a pressure relief valve to recirculate a portion of the coolant back to an inlet of the pump. Using the pressure relief valve includes actuating the pressure relief valve based on input from the cooling system and/or from the generator.

Abstract: A generator assembly for a high temperature environment that exceeds a seal temperature limit in operation can include a generator housing enclosing one or more generator components and one or more attached components sealed to the housing. The assembly can include one or more seals disposed between each of the one or more attached components and the generator housing and an oil circuit within the housing configured to circulate oil. The assembly can include one or more oil spray orifices within the housing and in fluid communication with the oil circuit. Each of the one or more oil spray orifices can be directed at an interior portion of the one or more attached components and/or an interior housing area adjacent the one or more attached components to provide oil spray thereto for cooling each of the one or more seals to maintain the one or more seals below the seal temperature limit.
