  • Patent number: 11671035
    Abstract: A method for operating a system having at least two mechanically coupled asynchronous motors, a computer program implementing the method and a system operating in accordance with the method are disclosed. One asynchronous motor is selected as master, with the other asynchronous motor(s) selected as slave(s). An effective (master) flux angle is measured in the motor selected as master and used as a basis for a setpoint value for controlling the flux angle of every other motor (slave) in the system. The flux angle of every slave motor is adjusted to the setpoint value as part of the control operation.

  • Patent number: 11146189
    Abstract: A control device for drives of a machine switches between normal operation and special operation depending on power demand from a power supply. In both operating modes, the control device cyclically determines preliminary current setpoint values. In normal operation, the current setpoint values match the preliminary setpoint values. In special operation, the control device dynamically determines a proportional factor for the drives depending on nominal and/or actual operating states of the drives. The control device determines current setpoint values by modifying the preliminary current setpoint values so that a respective drive draws no more power than the product of the respective proportional factor and the available total power. The current setpoint values and the current actual values are fed to drive controllers for the first drives, by means of which the preliminary first current setpoint values are determined. The control characteristics of the drive controllers include an integral part.

  • Patent number: 10327339
    Abstract: The present embodiments provide a circuit board. The circuit board may comprise a first main surface, a first soldering region located on the first main surface, the first soldering region including a plurality of first capture pads for connecting the circuit board with connection pins of an integrated circuit carrier, and a second soldering region for connecting the circuit board with a heat conducting surface of the integrated circuit carrier. The first capture pads of the first soldering region may be arranged on a boundary of a rectangle or square, where the second soldering region is arranged inside the boundary, and where the second soldering region is divided into multiple second capture pads with soldering barriers formed between adjacent second capture pads.

  • Patent number: 6678948
    Abstract: A method for connecting an electronic components to a carrier substrate is described. At least one pad of the component is connected electrically conductively to at least one pad on an upper surface of the carrier substrate. A solder bump is deposited on at least one of the pads to be connected, the component is alignedly mated with the carrier substrate, and the at least one solder bump is soldered in order to wet the contact surfaces. It is provided that during the soldering, the at least one solder bump is deformed within the contacting plane in such a way as to achieve a degree of deformation that permits the two-dimensional analysis of said degree of deformation by a radiograph of the interconnection site.

  • Patent number: 6666721
    Abstract: An easily producible and easily installable ignition mechanism for restraint devices in a vehicle includes an ignition capsule, in which at least one ignition element and its contact pins are fixed. Into the ignition capsule a pedestal can be set, in which a carrier arrangement having circuit elements is arranged. Spring elements are present, by which contact is established between circuit elements and contact pins of the ignition element when the pedestal is set into the ignition capsule.
