Abstract
Description
Titel: Blektromotor mit feststehender Welle undTitle: Sheet metal motor with fixed shaft and
umlaufendem Gehäuse. surrounding housing.
Anwendungs -gebiet: Die Erfindung betrifft einen Elektromotor mit feststehender Welle und einem, dem jeweiligen Anwendungsgebiet in seiner Form angepaßtem, umlauf endem Gehause.Field of application: The invention relates to an electric motor with fixed shaft and one, the shape of which is adapted to the respective field of application, circumferential housing.
Zweck: Bei, von Elektromotoren angetriebenen, Nashilinen, Anlagen und Aggregaten ist es notwendig, die erzeugte Kraft so verlustarm wie möglich zu übertragen, die Baueinheiten so klein wie möglich zu halten und aus Kostengründen Material einzusparbn.Purpose: In systems driven by electric motors and aggregates, it is necessary to use the generated power with as little loss as possible transferred to keep the units as small as possible and for cost reasons To save material.
Stalld der Technik: Heute werden Maschinen, Anlagen und Aggregate einerseits und Elektromotoren andererseits getrennt hergestellt und dann, meist starr, miteinander verbunden.Stalld of the technology: Today machines, systems and aggregates are on the one hand and electric motors on the other hand manufactured separately and then, mostly rigid, interconnected.
Kritik des Standes der Technik: Heute wird mehr Platz und Material benötigt, als eigentlich notwendig wäre. Die doppelte Lagerung, erstens des Elektromotors und zweitens des angetriebenen Maschinenteils ruft durch die Reibungsverluste der Lagerungen höhere Kraftverluste als notwendig hervor.Criticism of the state of the art: Today there is more space and material needed than would actually be necessary. The double bearing, first of all the electric motor and secondly the driven machine part gets through the friction losses of the Bearings result in higher power losses than necessary.
Aufgabe: Aufgabe der Erfindung ist es, bei der Baueinheit Maschine- Elektromotor die Reibungsverluste zu senken, die Baueinheitsgröße zu verringern und Material und damit Kosten zu sparen.Task: The task of the invention is to provide the machine Electric motor to reduce the friction losses, to reduce the unit size and to save material and thus costs.
Lösung: Die Reibungsverluste der Baueinheit Maschine-Elektromotor dadurch gesenkt, daß der Elektromotor mit feststehender Welle und umlaufendem Gehftise gleich als angetriebenes Haschinenteil in die Maschine, Anlage oder das Aggregat eingebaut wird. Das umlaufende Gehuse hat die äußere Form des angetriebenen Maschinenteils, z.3. Verdichterflügel, Rolle, Walze u.s.w. . Damit fallen mindestens zwei Lagerungen und die durch sie verursachten Reibungsverluste fort. Das Material für die zwei Lagerstellen wird eingespart. Die Baueinheit Maschine- Elektromotor wird durch das Hineinverlegen des Elektromotors in die Maschine wesentlich kleiner. Die Stromzuführung erfolgt von der Welle über Kohlen zur Wicklung. Auch bei Drehstrommaschinen ist dies durch drei separate Stromabnahmen auf der Welle möglich. Durch die Gestaltung des Gehäuses des Elektromotors in Form des angetriebenen Maschinenteils ist, bei verschiedenen Ausführungsmöglichkeiten, (z. B. Verdichterflügel, Rollen, Walzen u.s.w.), die völlige Esparung des Itaterials für das bisherige Gehäuse des Elektromotors möglich.Solution: The friction losses of the machine-electric motor unit lowered by the Electric motor with fixed shaft and revolving footstep is installed as a driven machine part in the machine, system or unit. The circumferential housing has the outer shape of the driven machine part, z.3. Compressor blade, roller, roller, etc. This eliminates at least two bearings and the friction losses they cause. The material for the two storage locations is saved. The machine-electric motor unit becomes significantly smaller by moving the electric motor into the machine. Power is supplied from the shaft to the winding via carbon. This is also possible with three-phase machines by means of three separate power take-offs on the shaft. Due to the design of the housing of the electric motor in the form of the driven machine part, with various design options (e.g. compressor blades, rollers, cylinders, etc.), the complete saving of the material for the previous one is possible Housing of the electric motor possible.
Weitere Ausgestaltung der erfindung: Bei verschiedenen Ausführungsformen, z.B. bei Windverdichterflügeln, kann weiterhin eine Wirkungsgradsteigerung des Elektromotors dadurch erreicht werden, daß kein Ventilator mehr zur Kühlung des Elektromotors benötigt wird und diese deshalb auch nicht angetrieben werden muß. Durch das Drehen des Gehäuses als Verdichterflügel im Luftstrom wird genügend Wärme abgegeben,um den Elektromotor kühl genug zu halten. Diese Art der Wirkungsgradsteigerung ist auch bei anderen Ausführungsformen des umlaufenden Gehäuses als angetriebenes Maschinenteil möglich.Further embodiment of the invention: In various embodiments, for example in the case of wind compressor blades, an increase in the efficiency of the electric motor can also be achieved can be achieved by the fact that a fan is no longer required to cool the electric motor is and therefore not driven must become. By rotating the housing as a compressor blade in the air flow, enough heat is given off to keep the electric motor cool enough. This type of increase in efficiency is also possible with other embodiments of the rotating housing as a driven machine part.
Erzielbare Vorteile: Zusammengefaßt ergeben sich folgende Vorteile gegenüber dem bisherigen System: Große Materialeinsparung ( Gehäuse, zwei Lager, Kühlventilator), Platzeinsparung ( der Raum für den gesonderten Elektromotor wird nicht mehr benötigt), Erhöhung des Wirkungsgrades des Elektgmotors ( es ent- fallt der Kühlventilator, außerdem sind die Reibungsverluste geringer).Achievable advantages: In summary, there are the following advantages compared to the previous system: Large material savings (housing, two bearings, cooling fan), Saving space (the space for the separate electric motor is no longer required), increasing the efficiency of the electric motor (it If the cooling fan falls, the friction losses are also lower).
