06 Nov 2008TL;DR: In this paper, the rotor position signals (H1-H4) are suppressed when the duration of a signal impulse exceeds a preset time period during the operation of electronically commutated motors (110, 112, 114, 116).
Abstract: The method involves suppressing rotor position signals when the duration of a signal impulse exceeds a preset time period during the operation of electronically commutated motors (110, 112, 114, 116). Unsuppressed rotor position signals (H1-H4) are continuously analyzed during the running of the motors. The current in all stator windings (120, 122, 126, 128, 132, 134, 138, 140) is simultaneously commutated by a current feeding arrangement i.e. n-channel MOSFET (158, 172), when it is analyzed that all permanent magnetic rotors (118, 124, 130, 136) ran through a preset rotor position. An independent claim is also included for an arrangement for controlling the synchronous running of multiple electronically commutated motors.

16 Nov 2016TL;DR: In this article, a thermodynamic cycle process system consisting of at least two heat exchangers, an EC compressor, and a combination of electronic components such as EC fans, electronic regulator valves and/or EC pumps is described.
Abstract: The present invention relates to a thermodynamic cycle process system comprising at least two heat exchangers, an EC compressor, and a combination of electronic components such as EC fans, electronic regulator valves and/or EC pumps. A central supply electronics unit can be connected to an AC voltage source, wherein the electronic components have an integrated power electronics device which produces the PWM operating voltage required for the electronic components. The central supply electronics unit is connected to the individual integrated power electronics devices for the electronic components, and produces the supply voltages required for the respective power electronics devices.

12 Jul 2001TL;DR: In this article, the authors describe a radial fan for a respirator with a drivable motor, axially between the inlet opening (4) and the outlet port (6) arranged in radial impeller.
Abstract: Radialgeblase (1), insbesondere fur ein Beatmungsgerat, mit einem Geblasegehause (2) mit einer zentralen axialen Einlasoffnung (4) und einer radialen oder etwa tangentialen Auslasoffnung (6) sowie mit einem motorisch antreibbaren, axial zwischen der Einlasoffnung (4) und der Auslasoffnung (6) angeordneten Radial-Laufrad (8), dadurch gekennzeichnet, das das Radial-Laufrad (8) auf seiner der Auslasoffnung (6) zugekehrten Axialseite eine Deckscheibe (10) mit einem derart grosen Durchmesser (D1) aufweist, das zwischen dem Ausenumfang (26) der Deckscheibe (10) und einer inneren Gehause-Umfangsflache (28) ein verengter ringformiger Stromungsspalt (30) fur das uber das Radial-Laufrad (8) in Richtung der Auslasoffnung (6) stromende Medium gebilded ist. The radial fan (1), in particular for a respirator, with a fan housing (2) with a central axial inlet opening (4) and a radial, or approximately tangential outlet opening (6) and with a drivable motor, axially between the inlet opening (4) and the outlet port (6) arranged in radial impeller (8), characterized in that the radial impeller (8) at its said outlet port (6) facing axial side of a cover plate (10) with such a large diameter (D1), in that between the outer circumference (26) the cover disc (10) and an inner housing circumferential face (28) a constricted annular flow gap (30) is for using the radial impeller (8) in the direction of the outlet opening (6) flowing medium gebilded.

28 Dec 2017TL;DR: In this paper, a fastening strut for a fan guard with at least one first leg extending in a longitudinal direction is described, configured so as to reach across several cage bars of the fan guard.
Abstract: The present disclosure concerns a fastening strut for a fan guard with at least one first leg extending in a longitudinal direction, configured so as to reach across several cage bars of the fan guard, wherein the at least one first leg comprises a free lengthwise end, and in the region of the free lengthwise end of the at least one first leg a cube-shaped or cuboidal fastening element is secured laterally to the at least one first leg by integral bonding in a transverse direction running perpendicular to the longitudinal direction.

10 Sep 2020TL;DR: In this paper, a verfahren zur Erkennung eines fehlerhaften Betriebs eines uber einen elektronisch kommutierten Gleichstrommotor angetriebenen Gasgeblases is described.
Abstract: Die Erfindung betrifft ein Verfahren zur Erkennung eines fehlerhaften Betriebs eines uber einen elektronisch kommutierten Gleichstrommotor angetriebenen Gasgeblases, wobei der Gleichstrommotor des Gasgeblases uber eine integrale Motorelektronik geregelt wird, wobei uber die Motorelektronik eine im Betrieb benotigte elektrische Stromaufnahme des Gleichstrommotors zur Erreichung einer vorbestimmten Geblasedrehzahl des Gasgeblases als Messgrose gemessen wird, wobei eine Plausibilitatskontrolle der gemessenen elektrischen Stromaufnahme durch die Motorelektronik erfolgt, bei welcher der gemessene Wert der elektrischen Stromaufnahme bei der vorbestimmten Geblasedrehzahl mit einer in der Motorelektronik hinterlegten Referenzwertkennlinie der Stromaufnahme verglichen wird und bei Abweichungen des gemessenen Werts der elektrischen Stromaufnahme auserhalb eines Toleranzkorridors um die Referenzkennlinie von der Motorelektronik eine Warnung und/oder ein Fehlercode ausgegeben wird.
