07 Jul 2005TL;DR: An arrangement with an electric motor, in the form of a small or miniature motor has a support flange (36) for guiding a locking element extending over at least one part of the periphery of the supporting flange and radially displaced inwards by an impact directed inwards as discussed by the authors.
Abstract: An arrangement with an electric motor, in the form of a small- or miniature motor has a support flange (36) for guiding a locking element (82) extending over at least one part of the periphery of the support flange (36) and radially displaced inwards by an impact directed inwards, and is designed so that it latches into the recess (94) after assembly of the support flange (36).

12 Sep 2013TL;DR: In this paper, a support element for an axial fan with a wall ring and an electric fan motor is presented, where the wall ring has a hinge consisting of a first hinge part that is connected to the wall and a second hinge part pivoted about a hinge axis relative to the first hinge.
Abstract: A fan, in particular an axial fan, comprising a support element with a wall ring and an electric fan motor which is mounted in the wall ring and comprises a fan rotor. The wall ring has on its outer periphery a hinge consisting of a first hinge part that is connected to the wall ring and a second hinge part that can be pivoted about a hinge axis relative to the first hinge part, wherein the second hinge part is designed as a terminal box for receiving electrical connectors. The invention further relates to a support element for such a fan.

05 Dec 2002TL;DR: In this paper, a method for generating an alarm signal in a motor which comprises a rotor (50) whose effective operating speed is in a standard zone (nSoll, TSoll) and can deviate from said standard zone if defective, and is to be monitored for such a defective state.
Abstract: The invention relates to a method for generating an alarm signal in a motor which comprises a rotor (50) whose effective operating speed is in a standard zone (nSoll, TSoll) and can deviate from said standard zone if defective, and is to be monitored for such a defective state. At least one alarm trigger speed (nAOn, TAOn) and at least one alarm switch-off speed (nAOff, TAOff) are determined, the latter being closer to the standard zone than the first. A hysteresis zone is defined between an associated pair of alarm trigger speed and alarm switch-off speed. If the speed to be monitored, starting from the hysteresis zone, approaches the alarm trigger speed, an alarm trigger criterion (Flag DIR=0) is generated (Fig. 13: S178). The duration of said alarm trigger criterion is monitored (Fig. 13: S184, 192). When the duration reaches a predetermined value (tdOn), an alarm signal (ALARM) is activated (Fig. 13: S186, 194). The invention also relates to a corresponding motor.

29 Jun 2013TL;DR: In this paper, anordnung zur fortlaufenden Uberwachung der voraussichtlich noch verfugbaren Lebensdauer eines Elektromotors (32) is presented.
Abstract: Eine Anordnung zur fortlaufenden Uberwachung der voraussichtlich noch verfugbaren Lebensdauer eines Elektromotors (32) hat eine Anordnung (20, 236) zur Erfassung eines ersten Wertes, welcher die Temperatur des Elektromotors (32) charakterisiert, eine Anordnung (240; 244) zur Erfassung eines zweiten Wertes, welcher die Drehzahl (n) des Elektromotors (32) charakterisiert, einen Speicher (31) zum Speichern eines digitalen dritten Wertes (Cr) fur die voraussichtlich noch verfugbare Lebensdauer des Elektromotors (32), und eine Rechenvorrichtung (30), welche dazu ausgebildet ist, – in zeitlichen Abstanden einen aktuellen Lebensdauer-Korrekturwert (Δt) zu erzeugen, der abhangig ist von dem erfassten Wert fur die Temperatur und dem erfassten Werte fur die Drehzahl (n), – den augenblicklich gespeicherten dritten Wert fur die voraussichtlich noch verfugbare Lebensdauer (Cr) abhangig vom berechneten aktuellen Lebensdauer-Korrekturwert (Δt) zu verandern, – das Resultat als neuen augenblicklich gespeicherten dritten Wert fur die noch verfugbare Lebensdauer (Cr) im Speicher zu speichern, und – das Signal als Funktion des gespeicherten dritten Werts zu erzeugen und auszugeben.

05 Feb 2009TL;DR: In this paper, an electronically commutierter electric motor (20) has a rotor (28) and a stator (26), where the stator during operation from an energy source (47) of electrical current (i1) for the drive of the motor(20) can be fed, which can have different values at the start of the engine.
Abstract: Ein elektronisch kommutierter Elektromotor (20) hat einen Rotor (28) und einen Stator, mit einer Statorwicklungsanordnung (26), wobei dem Stator im Betrieb aus einer Energiequelle (47) elektrischer Strom (i1) fur den Antrieb des Motors (20) zufuhrbar ist. An electronically commutated electric motor (20) has a rotor (28) and a stator with a stator winding (26), wherein the stator during operation from an energy source (47) of electrical current (i1) for the drive of the motor (20) can be fed , Der Motor hat einen digitalen Rechner (36), der zur Steuerung des regularen Starts des Motors (20) ausgebildet ist und dem ein PWM-Generator (84) zugeordnet ist. The motor has a digital computer (36) which is adapted to control the regular start of the engine (20) and is assigned to the a PWM generator (84). Der Motor (20) ist fur Betrieb in einem Parameterbereich ausgelegt, welcher mindestens einen variablen Parameter, z. B. die Betriebsspannung oder die Umgebungstemperatur, umfasst, der beim Start des Motors (20) unterschiedliche Werte haben kann. The motor (20) is designed for operation in a parameter range which at least one variable parameter z. B. the operating voltage or the ambient temperature covers, which can have (20) different values at the start of the engine. Der Mikrocontroller (36) ist zur Ausfuhrung folgender Schritte ausgebildet: Nach dem Einschalten des Motors (20) wird, vor dem Beginn des regularen Starts, wahrend einer ersten Phase (T1) der der Statorwicklungsanordnung (26) zugefuhrte Strom (i1) mit einem vorgegebenen, von dem mindestens einen variablen Parameter abgeleiteten Tastverhaltnis (pwm) gesteuert, um einen Start des Motors (20) zu bewirken; The microcontroller (36) is configured to perform the following steps: After switching on the motor (20) is, before the start of the regular start, during a first phase (T1) of the stator winding (26) supplied current (I1) given with a , controlled by the at least one variable parameter derived duty cycle (pwm), to effect a start of the engine (20); anschliesend an die erste Phase (T1) wird, wenn sich der Rotor (28) dreht, der regulare Start des Motors (20) durchgefuhrt. Subsequently, to the first phase (T1), when the rotor (28) rotates, the regular start of the engine (20) is carried out.
