  • Patent number: 11970114
    Abstract: A system for capturing and presenting views of a vehicle. In an example embodiment, the system captures video data rearward and along a side of the vehicle and/or behind the vehicle. The system includes video cameras for capturing video data at one or more resolutions and in one or more fields-of-view. The displays present the video data to the driver for use during operation of the vehicle. The displays present the video data at one or more resolutions. The resolution of capture and/or display may be in accordance with an operating mode of the vehicle, such as turning, direction of travel and/or driver selection.

  • Patent number: 10784745
    Abstract: A stator for an electrical machine (e.g., a motor or generator) is described. The stator includes a stator core consisting of a plurality of axially adjacent generally annular laminations. The stator has axially extending stator teeth between adjacent pairs of which are formed axially extending stator slots for receiving conductors of a stator winding. At least one of the stator teeth includes an axially extending cooling passageway through which a cooling fluid flows in use. The electrical machine can include means for circulating cooling fluid through the cooling passageway(s) to cool the stacked laminations and means for circulating air around the stator along an air cooling circuit where the circulated air is cooled by the stator laminations and there is no need for a separate heat exchanger.

  • Patent number: 9692262
    Abstract: 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 (6). To minimise the transmission of vibrations caused by stator electromagnetic forces into the external support frame (6), at least one sandwich anti-vibration mount (14a) is secured between the external support frame (6) and a part of the stator (28). The mount (14a) is oriented relative to the stator such that it experiences compression loading in a substantially tangential direction of the stator and radial shear loading in a substantially radial direction of the stator during operation of the rotating electrical machine. The sandwich anti-vibration mount (14a, 14b) is pre-loaded with a pre-determined compression load substantially along its compression axis (Ac).

  • Patent number: 8692433
    Abstract: 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.

  • Patent number: 8669680
    Abstract: 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.
