  • Patent number: 10416028
    Abstract: To determine the temperature of a link capacitor (C) of a link converter (1) more accurately with less expenditure, a device and a method are described, in which the link capacitor (C) is modeled as a series interconnection of an equivalent capacitance (CS) and an equivalent series resistance (ESR), wherein a modeled capacitor current (iCm) flows across the equivalent series resistance (ESR). A modeled capacitor power loss (PC), from which the capacitor temperature (TC) is determined by means of a specified temperature model, is calculated from the modeled capacitor current (iCm) and the value of the equivalent series resistance (ESR) by means of a first relationship of the form PC=f(iCm, ESR). Direct measurement of the capacitor temperature (TC), of the capacitor current (iC), or of the capacitor power loss (PC) is not required. For example, a measurement of the capacitor voltage (uC) and a further calculation of the modeled capacitor current iCm and finally of the capacitor power loss (PC) are sufficient.

  • Patent number: 8816552
    Abstract: The different electrical components and cables arranged in the B flange of an electric motor can be installed only with difficulties and are complicated and time-consuming due to the restricted space conditions in the B flange. In order to improve this, it is proposed to recess the B flange's 3 front side 10 facing away from the electric motor 1 at least in sections with respect to an imaginary surface normal to the longitudinal axis 15 of the electric motor 1 in the direction toward the motor housing 2, and to shape the B flange cover's 9 front face resting against the B flange 3 in a mirror-inverted manner to thereby improve the accessibility to the inside of the B flange 3.

  • Patent number: 7630799
    Abstract: A flight sensor for controlling electronic components in an aircraft includes a vibration sensor for converting structure-borne sound to electric vibration signals. A filtering device receives the vibration signals and determines the fraction thereof which is attributable to the aircraft engine, relative to the overall sound in the vibration signals. A comparator compares the engine sound with the overall sound and generates a flight condition signal based on the result of the comparison, which flight condition signal indicates a defined flight status of the aircraft, such as “flight” or “no flight”. Electronic components on board an aircraft are controlled such that the emission of interfering electromagnetic waves is prevented when the flight status signal indicates that the aircraft is in flight.

  • Patent number: 5095214
    Abstract: An optical hole seeking apparatus for webs (17) advanced in their longitudinal direction has two laser scanning devices (12, 15) which are arranged spaced apart along the web with a respective light receiving arrangement (11, 14) operating in reflection being associated with each laser scanning device. The two light receiving arrangements (11, 14) are connected to an electronic processing circuit (18) in which the two received photoelectric signals detected at the same position of the web (17) are correlated and then investigated to see whether they are the same or not.
