摘要： The invention relates to a current generator unit consisting of a generator and reciprocating engine as the drive system, in particular consisting of a synchronous generator and a diesel engine and comprising a cooling device for the common cooling of the generator and reciprocating engine. Said unit comprises a fan wheel (2) that axially aspirates the cooling air (L) on the motor side and evacuates the latter radially and that has a first passage (49) located in the radial exterior zone of the blades (4) and a second passage (50) located radially inside the blades (4). A small portion (S2) of the cooling air (L) ("generator cooling air") is fed exclusively to the generator on the motor side via the first passage (49) and is evacuated via the second passage (50) and a predominant portion (S1) of the cooling air (L) ("motor cooling air") is fed to the reciprocating engine.

摘要： The invention relates to a power generating installation that comprises a generator and a reciprocating internal combustion engine as drive, especially a synchronous generator and a diesel engine. Permanent magnets are disposed in the rotor of the generator in the pole zone to induce the rotor and a rotor winding (28) in the stator. In the pole zones of the rotor (29) at least one receiving pocket (34) is disposed in the axial direction and is open at least on one side. Said receiving pocket, with a cylindrical peripheral wall (50), borders the air gap (33) formed with the stator (11). The permanent magnets of the pole zone are constituted by a plurality of magnet elements (35) that are located side by side in the peripheral direction within the receiving pockets (34).

摘要： The invention relates to a method and system for assembling an electricity generating unit consisting of a generator and a reciprocating engine as the drive, in particular for centring an internal stator that is positioned inside an external rotor with an air gap. Said method comprises the following steps: mounting the external rotor onto the drive motor and connecting the rotor to the drive system of said motor; inserting at least two centring bolts, which are offset in the peripheral direction, into centring grooves that are provided in the rotor/stator for partially receiving, (when viewed from a radial direction), said centring bolts that bridge the air gap; centring the stator in the rotor by inserting said stator along the centring bolts inside the rotor; fixing the stator to the generator housing and fixing said generator housing to a connection housing of the drive motor; removing the centring bolts from the air gap.

摘要： The invention relates to a power generating installation that comprises a generator and a reciprocating internal combustion engine as drive, especially a synchronous generator and a diesel engine. The rotor (29) of the generator is driven as the outer rotor by the crankshaft (1) of the diesel engine and is provided with permanent magnets (35) that induce the generator. The stator (11) of the generator is disposed within the rotor (29) and carries the rotor winding (28) of the generator. The stator (11) of the generator, for the purpose of voltage control, is divided in a stator outer part (19) that defines an air gap (33) with the rotor (29), and a stator inner part (21) that defines a control air gap (23) with the stator outer part (19) surrounding it. The stator inner part (21) is mounted so as to be rotated with respect to the stator outer part (19) in such a manner that the geometry of the control air gap (23) changes with the rotational position and that the rotation is effected dependent of the variations in the terminal voltage of the generator.

摘要： The invention relates to a device for automatically regulating the voltage of a generator according to the load current. Said device comprises a first couple of clamps which can be connected to a couple of generator clamps carrying the load current and taps a first generator voltage from the generator coil, a second couple of clamps which can be connected to the couple of generator clamps and picks up a second generator voltage that is smaller than the first generator voltage from the generator coil, a third couple of clamps that supplies a control voltage to a control circuit which is provided with a control relay (9) having a switch for switching the connection between the couple of generator clamps and the first couple of clamps or the second couple of clamps. The couple of generator clamps, which is connected to the first couple of clamps by means of the switch, is connected to the second couple of clamps if the control voltage is greater than or equal to an upper threshold voltage of the control relay while the couple of generator clamps, which is connected to the second couple of clamps by means of the switch, is connected to the first couple of clamps if the control voltage is less than or equal to a lower threshold voltage of the control relay. The inventive device also comprises a bridging element that bridges the connection established by the switch between the couple of generator clamps and the first couple of clamps and is provided with a varistor, the on-state voltage of which lies above the difference between the two generator voltages but below the first generator voltage.
