Abstract: The dynamics of a magnetic gear mechanism are intended to be improved. For this purpose, a magnetic gear mechanism with a stator, a first rotor, which has permanently excited magnet poles (2, 3), and a second rotor, which likewise has permanently excited magnet poles, is proposed. The rotors are magnetically coupled to the stator. In each case one coil (5) is wound around each of the magnet poles (2, 3) of the first rotor. The coils (5) of the magnet poles (2, 3) are connected in series. The series circuit of the coils (5) can be supplied direct current in order to alter the magnetic flux through the magnet poles (2, 3) in comparison with the de-energized state.

Abstract: The invention relates to a system and a method for identifying automation components, particularly sensors, actuators and wiring components. According to the invention, each component (sensor, actuator, cable, compensation box, etc.) that is to be identified is equipped with an identification unit in which a code for identifying the automation component is stored and which outputs said identification code when being activated. Preferably, the identification unit comprises an electronic circuit (e.g. an RFID chip or a discreet circuit) while being provided with galvanically insulating (inductive, capacitive, radio-based) or galvanically conducting coupling to the component that is to be identified. The identification unit can be subsequently mounted on a component or can be inseparably connected thereto already during the production of the component.

Abstract: The invention concerns a method of coating shaped parts having a three-dimensional coating surface by the cathodic atomization of target material of a first cathode arrangement. The cathode arrangement comprises a magnetic field generator for the concentration of a first discharge space (plasma cloud) in the zone of the target surface by means of a first magnetic field (plasma trap), which is spatially closed with respect to the target. According to the invention and for the purpose of producing a uniform coating even on parts of complicated shape, it is proposed that, on their side disposed opposite the first cathode arrangement, the shaped parts should be simultaneously subjected to the atomizing action of a second cathode arrangement with the same target material.
