  • Patent number: 12212256
    Abstract: A method and a control apparatus for determining parameters for controlling an electric drive having an electric machine improve the start-up of the electric drive by applying a current indicator as a signal at three-phase winding connections of the electric machine, and measuring a d-component and a q-component of the stator voltage and of the stator current at the winding connections. In a first measurement step, a rotating current indicator is applied to the three-phase winding connections and the electric machine is oriented such that an exciter current in the q-axis assumes a minimum. In a second measurement step, when the rotor of the electric machine is stationary, a field winding of the electrical machine is short-circuited and a current indicator in form of a binary noise signal is applied to the winding connections. A stator impedance is then determined as a first control parameter.

  • Publication number: 20180340734
    Abstract: The invention relates to an electric arc furnace and a method for operating same. The electric arc furnace comprises a lower vessel and a lid 120 placed on said lower vessel. The lower vessel has a tapping device for tapping molten metal. At least one electrode protrudes through the lid into the interior of the electric arc furnace, said electrode being held by an electrode holding device. A supply voltage device 150 is provided for supplying an electric direct current or alternating current to the electrode 130. The aim of the invention is to allow a continuous operation of the electric arc furnace. This is achieved in that the electrode holding device has an electrode adjusting device for adjusting the electrode dependent on the wear of the electrode and an electrode nippling device for nippling the electrode during the operation of the electric arc furnace.

  • Patent number: 9774077
    Abstract: A radome having a core layer and two cover layers and method of forming the radome. The core layer is arranged between the two cover layers. Each of the two cover layers is composed of a plurality of partial layers which, by their respective dielectric constant, are embodied such that the radome provides a high mechanical stability and a high electromagnetic transparency. The dielectric constant of adjacent partial layers thereby alternates from relatively high to relatively low in the direction towards the core layer, and vice versa.
