  • Patent number: 8269381
    Abstract: The mounting of a coolant line system in a magnet device of an electric machine is to be simplified. Therefore, a magnet device is provided, with a ferromagnetic base member (4) comprising a first (3) and an opposite second side (5) and comprising penetration holes for coolant lines from the first side (3) to the second side (5), and a plurality of first coolant line segments (1) inserted through the holes. The first coolant line segments (1) are U-shaped and each of the free leg ends (2) thereof is inserted through two of the holes of the first side (3) such that the leg ends (2) protrude from the second side (5) of the base member (4). Two of the leg ends of the first coolant line segments (1) are connected by way of a second coolant line segment. Thus, only two types of coolant line segments are needed to construct the coolant line system, and also the coolant line segments can be connected at a single side (5) of the base member (4).

  • Patent number: 8261884
    Abstract: A mechanical energy storage system includes a containment vessel, a drive shaft operatively connected to a generator/motor and supported for rotation in the containment vessel. A support structure is attached to the drive shaft and configured for radial extension from a rest position proximate the drive shaft. A resilient member having a mass and extending circumferentially around the drive shaft is connected to free ends of the support structure and configured to store elastic energy when the support structure extends radially from its rest position. Upon rotation of the drive shaft, the resilient member stores both elastic and rotational energy commensurate with its mass and elastic properties.

  • Patent number: 8264209
    Abstract: The invention relates to a method and a device for operating an asynchronous motor (1) with double feeds, having a stator (1a) connected to a grid and a rotor (1b) connected to an inverter (6), said inverter (6) being designed such that it impresses a target value for an electrical variable in the rotor (1b). In a method according to the invention, after detecting a transient grid voltage change, a target value for the electrical variable determined from at least the rotor flux and the stator flux is impressed in the rotor (1b) such that an active reduction in the torque occurring during the transient grid voltage change is achieved. The target value of the electrical variable is preferably determined from a suitable weighting of the stator flux, rotor flux, stator voltage, stator current, rotor current, and, if available as a measured variable, stator voltage.

  • Patent number: 8256261
    Abstract: In a method of making through-passages in a perforated U-shaped sheet metal part, an inner core is positioned between confronting legs of the sheet metal part in an area of holes, and a support bar is inserted through one hole into the sheet metal part for support of a backside of the inner core. A shaping punch is inserted through another opposite hole into the inner core, thereby forming an inwardly directed collar. After retracting the support bar and the shaping punch and transferring the sheet metal part to replace the first inner core with a second inner core, a centering bar is inserted through the collared hole into the sheet metal part to center the sheet metal part in relation to the centering bar and to support a backside of the other inner core. A further shaping punch is then inserted into the second inner core through the first hole, thereby forming an inwardly directed collar so that the two collars are aligned and form through-passages.

  • Patent number: 8247923
    Abstract: A photovoltaic system having a plurality of photovoltaic modules producing electric energy and method for operating such photovoltaic system are disclosed. With the method, the photovoltaic modules are connected to a first DC motor having a motor shaft, and a generator shaft of a three-phase generator is coupled to the motor shaft. The three-phase generator can be connected to a power grid. The motor shaft of a second DC motor can be connected to the generator shaft, with only one of the two DC motors being initially driven with the electric energy produced by the photovoltaic modules. The electric energy is subsequently divided among both the first and the second DC motor. This process significantly shortens the startup process of the photovoltaic system compared to conventional systems.

  • Patent number: 8242753
    Abstract: In a method and an apparatus for controlling the output or drawn active and reactive power of a double-fed asynchronous machine (5), the maintenance of a maximum permissible current (16) of the machine—without the use of a subordinate current controller—is ensured by virtue of the fact that, during the operation of the double-fed asynchronous machine, a maximum permissible desired value for the active power (10a) to be output or to be drawn and a maximum permissible desired value for the reactive power (10b) to be output or to be drawn are calculated with the aid of a model of the asynchronous machine from the maximum permissible current (16), preferably corrected at least using the actual value of the current to be limited of the machine, in such a way that the maximum permissible current (16) is not exceeded. The predetermined active and reactive power desired values are then limited to the calculated maximum permissible values.
