  • Patent number: 10315280
    Abstract: A press frame for a robot system includes a base, a bridge and a set of columns supporting the bridge above the base. A first robot holds a part on the base and a second robot manipulates a pressing tool to press a component into an opening. The pressing tool is backed by the bridge that opposes a reaction force resulting from pressing the component part into the part. A method of assembling components to a part by pressing the part into an opening while engaging the bridge of a reaction frame. The part is transferred to the base by a first robot that positions the part on the base. A pressing tool and a component are selected by a second robot that orients the component to be inserted in the opening. Data relating to displacement, load and time is collected by the controller.

  • Patent number: 10310016
    Abstract: The present invention is concerned with a method for diagnosing the state of electromechanical systems in which electrical rotating machinery is used on the basis of analysis of impedance estimated from at least two currents and two voltages, measured during an operation of the electromechanical system. The method may be especially useful in the condition monitoring of electric motors and generators. The invention combines the information from both the voltage and current signals measurable at the motor terminals. Specifically, the measurements of voltage and current from two or more phases of a polyphase electrical machine are combined to estimate the impedance of the machine, impedance being the resistance to the flow of current that a circuit exhibits when a voltage is applied to it.

  • Patent number: 9903903
    Abstract: A method for deriving at least one operating parameter of a fluid-insulated electrical apparatus, in particular of gas-insulated switchgear. The operating parameter is dependent on a dielectric breakdown strength of an insulation fluid of the electrical apparatus. The insulation fluid includes at least three components that are assigned to at least a first and a second component group such that at least one component group comprises at least two components. The component groups differ in their weighted average values of the molecular masses of the components in the respective component groups. At least one quantity which is indicative of the concentration of the first component group and of the concentration of the second component group is determined from the insulation fluid, e.g. by measuring one or more measurement variables with one or more sensors. The operating parameter is then derived using the at least one quantity.
