  • Fault-tolerant electrical generator operable with partial power
    Patent number: 9787160
    Abstract: An electrical machine with a rotor or the stator including a plurality of discrete field modules, and the other one of the rotor and the stator including a plurality of armature coils connected to different power converters. Each field module includes one or more field coils which can be activated independent of the field coils of the neighbouring field modules. When at least one of the field coils is inactivated, e.g. because of a defect, each of the power converters is allowing less power to pass through when an armature coil connected to it is moving over an inactivated field coil, and more power to pass through when the armature coil connected to it is moving over an activated field coil.

  • Modular Rotor For Synchronous Reluctance Machine
    Publication number: 20120146448
    Abstract: A rotor for a synchronous reluctance machine includes a plurality of rotor modules disposed in an axial sequence along a common axis. Each rotor module includes a plurality of poles disposed in adjacent sectors about the common axis, each pole including a plurality of magnetic segments spaced apart from one another in radial direction, a support plate, provided on an axial side of the plurality of poles, and fastening means for fastening the plurality of poles to the support plate. The fastening means, preferably a plurality of axially arranged bolts or an adhesive, bonds the plurality of poles to the support plate.
