  • Patent number: 8631571
    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.

  • Patent number: 7821171
    Abstract: A wedge placed between adjacent coils in a generator comprises a wedge body having a generally triangular portion to be positioned at a radially inner location, and a radially outer portion. The radially outer portion includes ends that will be spaced at axial ends of the wedge when the wedge is positioned within a generator. The ends have a first surface spaced a first distance from an apex of the triangle. The end walls extend above the first surface at each of two spaced positions axially inwardly of the ends of the wedge. The end walls are connected to side walls that extend near circumferential edges of the wedge. An open pocket is formed within the wedge body at locations between the side walls and axially between the end walls.

  • Patent number: 7791238
    Abstract: A motor driven assembly includes a motor having a motor shaft mounted for rotation about a rotational axis and a rotor radially located about the shaft. The motor drives a compressor that receives air from the motor, compresses the air, and circulates the compressed air to a space. The motor includes a first cooling flow passage and a second cooling flow passage that each receive air to provide internal cooling of the motor. A portion of the air compressed in the compressor is diverted from the compressor to a heat exchanger. The heat exchanger cools the compressed air from before the air circulates into the first cooling flow passage to cool the motor. The second cooling flow passage receives air from the environment surrounding the motor driven assembly to further cool the motor.

  • Patent number: 7627941
    Abstract: An alignment fixture includes a rotor fixture, a stator fixture and a sensor system which measures a rotational displacement therebetween. The fixture precisely measures rotation of a generator stator assembly away from a NULL position referenced by a unique reference spline on the rotor shaft. By providing an adjustable location of the stator assembly within the housing, the magnetic axes within each generator shall be aligned to a predetermined and controlled tolerance between the generator interface mounting pin and the reference spline on the rotor shaft. Once magnetically aligned, each generator is essentially a line replaceable unit which may be readily mounted to any input of a multi-generator gearbox assembly with the assurance that the magnetic alignment will be within a predetermined tolerance.
