Fan for conveying media

Abstract: The blower has a sealing (22) arranged at a side of a rear front wall (8) of a housing in such a manner that the sealing in a position, which seals an opening gap, lies against a through hole under axial prestressing at the rear front wall of the housing in a sealed and surrounded manner. The sealing includes a clamping element (32) made of spring-elastic material i.e. spring steel, and a sealing element (23) made of non-elastomer material i.e. PTFE, where the sealing element is fixed between the clamping element and the rear front wall in a force-fit manner.

Network configuration and method for allocating network addresses to ventilator in a network

Abstract: The present invention relates to a method for configuring a network (10) with network addresses (ID), wherein the network (10) (20) and a plurality of fans (30) consists of at least a central computer, which via a bus system (11 ) wired and / or wireless (with the central computer can communicate 20), each fan (30) via a rewritable memory (31) and a RFID interface (32) for communicating with a preferably mobile communications device (33), wherein the memory (31) of the respective fan whose serial number (S) is stored, and the serial number (S) in the inoperative unstressed condition of the respective fan (30) from the communication device (33) can be read.

Electronically Commutated Motor & Method for Controlling the Same

Abstract: The invention relates to an electronically commutated motor ( 10 ) and to a method of controlling an electronically commutated motor ( 10 ). In order to reduce commutation noise, it is proposed to influence the working range of the power-stage transistors ( 20, 22 ) with the aid of a component ( 48 ), in such a way that each transistors produces, during energization of each respective stator winding, a substantially constant current through the stator winding ( 12, 14 ). Preferably, each power-stage transistor operates within a pinch-off range.

Fan for equipment comprises an air-conveying channel containing a fan wheel rotating about a central axis and having a central hub with an outer periphery on which fan blades are fixed

Abstract: Fan (10) comprises an air-conveying channel (16) containing a fan wheel rotating about a central axis and having a central hub (20) with an outer periphery (27) on which fan blades (26A-26E) are fixed. The fan blades extend with their radial outer edges up to a surface (17) arranged coaxially to the central axis and externally defining the air-conveying channel. The fan blades have sickle-shaped concave front edges and are provided in the region of their radial outer edges with a flow element (winglet) (42A-42E) designed as an obstruction for a compensation flow running about this radial outer edge from the pressure side to the suction side. Independent claims are also included for alternative fans.

Elektromotor mit vereinfachter Montage

Abstract: Elektromotor (100), welcher aufweist: Eine Statoranordnung (116), eine Rotoranordnung (140) mit einer Rotorwelle (144), welche ein erstes, freies Wellenende (197) und ein zweites Wellenende (196) aufweist, ein Lagerrohr (190) mit einer Ausnehmung (194), durch welche bei der Montage das erste Wellenende in das Lagerrohr (190) einfuhrbar ist, eine im Lagerrohr angeordnete Lageranordnung (125) zur Lagerung der Rotorwelle, einen Sicherungsring (120) mit einer Ringoffnung und einem Schlitz um eine Aufweitung der Ringoffnung zu ermoglichen, welche Rotorwelle eine Ringnut aufweist, an welcher der Sicherungsring angeordnet ist, welcher Sicherungsring im Lagerrohr zwischen einem ersten Sicherungsringanschlag und einem zweiten Sicherungsringanschlag axial verschiebbar ist, wobei der erste Sicherungsringanschlag dazu ausgebildet ist, bei der Montage ein Einschieben der Rotorwelle in die Ringoffnung zu ermoglichen, und wobei der zweite Sicherungsringanschlag eine Bewegung des Sicherungsrings in Richtung zum zweiten Wellenende hin begrenzt, um eine Bewegung der Rotorwelle zumindest in die Richtung aus dem Lagerrohr hinaus zu begrenzen.
