Mixing device for mixing combustion air and gas, and firing device

Abstract: The invention relates to a mixing device for premixing combustion air and gas, having a gas regulating device and a gas outlet and a nozzle, wherein a gas inlet is provided on the nozzle or on a bridging element disposed on the nozzle, and the gas path from the gas outlet to the gas inlet is sealed off by a gasket extending from the gas outlet to the gas inlet.

Method for monitoring rolling bearings

Abstract: The present disclosure relates to a method and an apparatus for monitoring a rolling bearing of an electric motor, wherein the rolling bearing forms a capacitive parasitic antenna, having the following steps of: a capturing the electromagnetic spectrum emitted by the parasitic antenna in a manner triggered by spark formation in the rolling bearing over a respectively defined period t during operation of the electric motor; b evaluating the number N of electromagnetic pulses (a, b, c, d, e) received in the spectrum and the amplitude A of said pulses; c capturing the change in the number N of electromagnetic pulses (a, b, c, d, e) and/or the amplitude A of said pulses, and d determining whether the increase in the number N and/or in the amplitudes A of the electromagnetic pulses (a, b, c, d, e) increases in a non-linear manner with time

Verfahren zum Betrieb eines elektronisch kommutierten Motors, und Motor zur Durchführung eines solchen Verfahrens

Abstract: Es handelt sich um ein Verfahren zum Betrieb eines elektronisch kommutierten Motors, welchem ein Mikroprozessor oder Mikrocontroller und ein diesem zugeordnetes Programm zugeordnet sind, welches Programm zur Steuerung einer Mehrzahl von Motorfunktionen unterschiedlicher Prioritat dient und folgende Schritte aufweist: Es wird eine Mehrzahl von fur den Betrieb des Motors erforderlichen, anforderbaren Routinen vorgesehen, welche nicht Interrupt-Routinen sind; wenn eine anforderbare Routine benotigt wird, wird ein entsprechendes Anforderungssignal fur sie gesetzt; durch eine ubergeordnete Programmfunktion wird gepruft, welche der angeforderten Routinen die hochste Prioritat aufweist, und diese Routine hochster Prioritat wird als erste ausgefuhrt; nach Ausfuhrung dieser Routine hochster Prioritat wird das dieser Routine zugeordnete Anforderungssignal ruckgesetzt.

Method for producing a drive unit device

Abstract: The invention is based on a method for the production of a drive unit device, in particular of a fan device, which has at least one first modular unit (12) and at least one second modular unit (16) which concentrically receives at least part of the first modular unit (12), wherein the first and second modular units (12, 16) are intended to cooperate mechanically in a change in torque, wherein in at least one method step (100, 110) the first modular unit (12) is secured in the second modular unit (16). In order to increase safety and reduce method costs, it is proposed that the first modular unit (12) be secured in the second modular unit (16) by at least one concentric pressing process step.
