摘要： 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.

摘要： A rotating electrical machine and method for making the machine, where the machine includes a high-voltage stator winding and elongated support devices for supporting the winding. The machine and method employ an arrangement of cable that is made of inner conductive strands, covered with a first semiconducting layer, which is covered with an insulating layer, which is covered with a second semiconducting layer. The cable is wound in slots in the stator such that separate cable lead-throughs are positioned in specific arrangements with respect to each other and in slots of the stator. The arrangement of the cable in the stator protects the integrity of the respective components in the cable and particularly the second semiconducting layer.

摘要： In a plant comprising one or more electric machines constructed with insulated conductors and connected for heavy current via insulated conductors, the magnetic circuit in at least one of these electric machines is connected directly to a high supply voltage of 20-800 kV, preferably higher than 36 kV. The insulation of the electric machine is built up of a cable (6) placed in its winding and comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by outer and inner semiconducting layers (34, 32) and intermediate insulating layers (33). The conductors (31) may be group-wise connected in parallel and semiconducting layers are therefore not required around every conductor in the group. If the conductors (31) are connected in series with each other within the group a part insulation (35) is required which will withstand a few kV, whereas connection of the conductors (31) to every phase requires a strong part insulation (35) which will withstand the phase voltage of the high-voltage supply network.

摘要： Methods and devices for performing a selection action of information in a central system before communicating selected information to a user terminal. The selection is based on at least the identity of the user and position of the user terminal. Using relations between identity and profiles, a first information filtering can be achieved. Using relations between the actual position of the user terminal and constitution of the industrial automation facility, information irrelevant for parts in the vicinity of the user terminal is removed. The operational situation of the facility and history of user actions may be used for filtering or prioritizing the information. The most prioritized data quantity is communicated to the user terminal and displayed at a user terminal display. If all the data, despite sifting, is too extensive to be shown at once on the user terminal, the user may move between different parts of the relevant information.

摘要： The present invention discloses methods and devices, with which a selection action of information is performed in a central system before communicating the selected information to a user terminal. This selection (4,6) is according to the invention based on a least both the identity (9) of the user and the position (11) of the user terminal. By using relations between identity (9) and profiles (8) a first information filtering can be achieved. By further using relations between the actual position (11) of the user terminal and the constitution of the industrial automation facility, information irrelevant for the parts in the vicinity of the user terminal is removed. Preferably, also the operational situation of the facility and the history of the user actions are used for filtering or prioritising the information. The most prioritised data quantity is communicated (12) to the user terminal (13) and displayed at a user terminal display. If all the data, despite the sifting, is too extensive to be shown at once on the user terminal (13), the user may by one or a few key presses or mouse actions zap between different parts of the relevant information.
