  • Patent number: 11005351
    Abstract: An automotive electric fluidic pump includes a brushless and electronically commutated electric drive motor. The electric drive motor includes a permanent-magnetic motor rotor which rotates around a rotation axis and includes rotor poles, stator-sided electro-magnetic coils, a printed circuit board with openings, at least two stator-sided Hall sensors arranged on a proximal side of the printed circuit board to face the permanent-magnetic motor rotor, and a ferromagnetic back iron member arranged at a distal side of the printed circuit board to provide a direct magnetic coupling of the Hall sensors with each other. The Hall sensors are arranged eccentrically to detect axial magnetic fields of the rotor poles. The ferromagnetic back iron member comprises axial protrusions. An axial protrusion extends into an opening of the printed circuit board. Each axial protrusion faces a Hall sensor.

  • Patent number: 10224837
    Abstract: A method for starting a drive motor. The drive motor includes a motor stator with stator coils and a motor rotor, and a control electronics system and a power electronics system which supply power to the stator coils with a predefined coil voltage and a predefined constant start-up rotation frequency to generate a rotating field to drive the motor rotor. The method includes supplying power to at least one stator coil with a coil voltage corresponding to a start value, increasing the coil voltage in steps, monitoring an electric current flowing through the power electronics system, and, when a specific minimum voltage drop is detected, terminating the increasing of the coil voltage in steps, and performing a safety increase of the coil voltage by increasing a start-up voltage value by a predefined safety value to a first operating voltage value where the motor rotor is drivable in an unregulated mode.

  • Patent number: 7522277
    Abstract: The present invention relates to an imaging optical system for imaging the peripherally extending lateral surfaces (9) of an object (10) on to an imaging plane, comprising a reflecting element (6) and a first angle-reducing element (3, 17) which is arranged downstream of the reflecting element in the beam direction and which reduces the angle between a light beam emanating from the object (10) and the optical axis (12). In order to provide an imaging optical system for imaging the peripherally extending lateral surfaces of objects, which is both simple and inexpensive to produce and also has a large acceptance angle for the incident radiation and which is tolerant in relation to inaccurate positioning of the object, it is proposed in accordance with the invention that arranged upstream of the reflecting element (6) in the beam direction is a second angle-reducing element (13) which reduces the angle between a light beam (1, 1) emanating from the object (10) and the optical axis (12).

  • Publication number: 20080122365
    Abstract: This application document describes a method of supplying pulsed power to light bulbs of different output ratings in motor vehicles. The pulse width (duty cycle: ratio of pulse duration and period duration) is adjustable by detecting the bulb current (I), determining the nominal output of the light bulb that power is to be supplied to, and adapting the pulse width to the bulb current (I) detected.

  • Patent number: 5750949
    Abstract: A metal-encapsulated, gas-insulated high-voltage circuit-breaker includes a fixed contact configuration which is accommodated in its own fixed contact housing, and a moving contact piece configuration which is driven by a first drive and is accommodated in a contact housing that is connected to the moving contact piece configuration or can move with said contact piece configuration during a switching operation. The contact configurations may have contact pieces for a rated current and for guiding and extinguishing an arc. At the same time, a device is provided for producing a gas flow. The device includes a dielectric nozzle in which the arc burns and is blown and which is guided in a sealed manner in the fixed contact housing throughout an entire switching operation.

  • Patent number: 4251924
    Abstract: The drying medium (T) is driven through the adsorbent (5) of the adsorption cell (1) in the same direction as the process medium (P). Initially it is ejected through an auxiliary output (19) and a device (26) for removal of dampness and then is changed-over towards a main output (18) and preferably into the workroom (A).

  • Patent number: 4021211
    Abstract: A process and apparatus for separation of solvents from an air stream laden with solvent vapors by adsorption using active carbon followed by regeneration of the carbon by desorption by steam using a plurality of active carbon chambers. The sequence of charging and regeneration of the active carbon is controlled automatically in dependence upon the concentration of solvent vapors in the air stream. During the change over from charging to regeneration the active carbon is first subjected to desorption by steaming with a large volume of steam and then, when steam breaks through on the outlet side of the carbon the volume of steam is reduced for the purpose of drying the carbon. The change over is effected by a measuring device arranged on the outlet side of the carbon chamber responsive to a pre-determined threshold concentration of solvent vapors in the outgoing stream.
