20130034437 | FASTENING DEVICE PARTICULARLY SUITABLE FOR THE FASTENING BETWEEN AN AIR INTAKE AND AN ENGINE OF AN AIRCRAFT NACELLE - An aircraft nacelle includes a first conduit for an air inlet and a second conduit for an engine, arranged end to end and connected by an annular flange, attached to the air inlet, and an annular flange, attached to the engine. The annular flanges are connected by a plurality of passage holes in the annular flanges and arranged in line with each other. Rods are housed in the passage holes. For at least one rod, the passage hole of one of the annular flanges has a diameter greater than the diameter of the rod allowing the rod to move in case of deformation of one of the two conduits. An angle profile is inserted between the rod and a cylindrical portion adjacent to the annular flange and. is connected to the adjacent cylindrical portion through the intermediary of at least one means for absorbing eventual deformations in radial direction. | 02-07-2013 |

20100186592 | Air Cleaners for Electrical Machines - The present invention provides an air cleaner suitable for forced air open-ventilation systems used to cool electrical machines. The air cleaner comprises an air chamber with a first end where air is drawn in from the surroundings, via an inlet, by the open-ventilation system and a second end, opposite the first end, where air is drawn out of the air chamber, via a first outlet, by the open-ventilation system. A rotating means is contained within the air chamber and may be driven to rotate about an axis that extends between the first end and the second end of the chamber. When driven to rotate, the rotating means applies a centrifugal force to any particles contained in the air entering the air chamber and throws them radially outwards from the central axis. These particles are then drawn out of the air chamber, via at least one second outlet formed adjacent to a radially outer edge of the rotating means, by a high-velocity outlet stream of the open-ventilation system. | 07-29-2010 |
20130214628 | WIND TURBINE GENERATORS - A wind turbine generator has a drive end at which one or more turbine blades are mountable and a non-drive end. The wind turbine generator comprises an external stator having a radially inner surface and an internal rotor having a radially outer surface, an air gap being defined between the rotor and the stator. A main bearing arrangement is provided at the drive end and acts between the rotor and the stator to mount the rotor for rotation about the stator and a stabiliser beating is provided at the non-drive end and acts between the rotor and the stator to stabilise the rotor and stator and maintain and control the air gap therebetween. | 08-22-2013 |

20100096942 | Rotor or a stator for a superconducting electrical machine - A rotor (or a stator) for a superconducting electrical machine includes a mounting that is maintained at substantially ambient temperature during operation of the electrical machine and a field coil support structure. A plurality of superconducting field coils are maintained at cryogenic temperatures during operation of the electrical machine and are supported by the field coil support structure. At least one coupling element is used to fix the field coil support structure to the mounting. The field coil support structure is preferably fixed to the mounting by a plurality of substantially circumferentially extending coupling elements at a first and second axial end of the field coil support structure and the mounting such that the mounting and field coil support structure are substantially separated over their axial lengths by a vacuum gap. | 04-22-2010 |

20100225121 | Rotating Electrical Machines - A torsional vibration damper is integrated into a rotating electrical machine. A rotatable assembly of the electrical machine includes a rotor core pack having a first end and a second end. The integrated torsional vibration damper consists of a torsional elastic coupling and a torsional elastic damper and provides mechanical damping. The integrated torsional vibration damper is mounted to the rotatable shaft of the electrical machine by a flange. The rotor core pack is mounted at the first end to the integrated torsional vibration damper by suitable structure members such as a mounting flange and is not fixedly mounted directly to the rotatable shaft. In the case where the rotor core pack is cooled by circulating coolant fluid (e.g. MIDEL) then the integrated torsional vibration damper may be a viscous damper that uses the coolant fluid as a viscous working fluid. | 09-09-2010 |
20120169156 | Suspension Structures - A support structure is used to mount the stator of a rotating electrical machine (e.g. a motor or generator). The support structure includes a rigid external support frame ( | 07-05-2012 |
