The machine unit includes a stator, which includes a plurality of magnetic flux conductors and an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and a movable element, which includes permanent magnet elements movable in a reciprocating movement in relation to the stator along a movement path. The winding path includes a first current carrying portion, which extends substantially in parallel with the movement path. Each magnetic flux conductor is arranged to form, together with one of the permanent magnet elements, a closed magnetic flux circuit extending around the current carrying portion.

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.
