Description

Es ist bekannt, tragbare Kompressoren durch Kombination von Elektromotor mit Kompressor dadurch herzustellen, daß der Kompressor direkt von der Motorwelle angetrieben wird: Bei -diesen Kompressoren ist "es unangenehm, wenn bei Störungen im Motor, vor allem beiden am häufigsten vorkommenden Statorstörungen, ein Ausbauen de3 Motors und der Motorwelle notwendig ist.It is known to use portable compressors by combining an electric motor to produce with a compressor that the compressor directly from the motor shaft is driven: With these compressors "it is uncomfortable when there is a fault in the motor, especially the two most common stator faults, an expansion de3 motor and the motor shaft is necessary.

Die Erfindung betrifft einen Elektrokompressor, insbesondere einen tragbaren Elektrokornpresisor, und besteht darin, daß der den Stator tragende Motorteil auswechselbar in einem -den Fuß tragenden Lagerteil befestigt wind. Hierdurch werden Störungen im Motor durch Auswechselndes Stators behoben, ohne daß die Maschine einer Werkstatt oder einer Fabrik zur Behebungsdes Motorschadens zugesandt zu werden braucht und stets einsatzbereit ist, weil ein Ersatzstator vorrätig behalten werden kann. Es erscheint ferner zweckmäßig, den Elektromotor bei Elektrokompressoren in an sich. bekannter Weise so auszubilden, daß er für verschiedene Spannungen benutzbar ist. Um äußerlich am Gehäuse anzuzeigen, für welche Spannung -die Wicklung geschaltet ist, wird erfindüngs@F emäß auffallend am Schaltbrett für den Anlaßschalter eine Schlitzschraube angeordnet, deren Schlitz als Hinweis für die eingeschaltete Spannung dient und ;darauf hinweist, beim Einschalten (des Motors festzustellen, ob auch die eingestellte Spannung an den Motor angelegt wird. Es: erscheint ferner vorteilhaft, den Fliehkraftschalter - des-- Motors unter einem leicht lösbaren Deckel am filterfreien Motorschild in einer zentralen Schildeinbuchtung zu lagern; wodurch der Fliehkraftschalter bei Unregelmäßigkeiten leicht zugänglich ist und beobachtet werden kann.The invention relates to an electric compressor, in particular one portable Elektrokornpresisor, and consists in that the motor part supporting the stator interchangeable in a bearing part that supports the foot. This will be Malfunctions in the motor corrected by replacing the stator without the machine having a To be sent to a workshop or factory to have the engine repaired and is always ready for use because a replacement stator can be kept in stock. It also appears expedient to use the electric motor in itself in electric compressors. known way to train so that it can be used for different voltages. To indicate on the outside of the housing the voltage for which the winding is switched is, erfindüngs @ F emäß noticeably on the switchboard for the starter switch Slotted screw arranged, its slot as an indication of the switched on voltage and; indicates that when the motor is switched on (to determine whether also the set voltage is applied to the motor. It: also appears advantageous, the centrifugal switch - of the engine under an easily removable cover on the filter-free To store the engine shield in a central shield indentation; whereby the centrifugal switch is easily accessible and can be observed in the event of irregularities.

In der Zeichnung ist als Beispiel schematisch eine Ausführungsform des Erfindüngsgegenstande s nach Fig. i in teilweisem Schnitt und nach Fig. 2 in Au@-sicht auf,das Motorschaltbrett dargestellt.In the drawing, an embodiment is shown schematically as an example of the subject matter of the invention according to FIG. 1 in partial section and according to FIG. 2 in Au @ view of the motor control panel shown.

In dem -'L\lot-orgehäuse i ist mittels ödes, Lagers 2 ein Elektromotor gelagert, auf dessen verlängerter Welle 3 der Exzenter 4 zur Betätigung des- Kompressors 5 und Idas Lüfterrad 6 befestigt sind. Vor dem Lüfterra:d 6 ist Idas Filter 7 in der Gehäusewand angeordnet, das mittels des Griffes 8 herausnehmbar ist. Die durch,das Filter 7 mit seiner Luft-Leitvorrichtung g dem Lüfterrad.6 zugeleitete Luft wird. ,durch das Lüfter rad komprimiert und als vorkomprimierte Luft dem Kompressor 5 zugeleitet, während die überschüssige Druckluft durch den ringförmigen Kanal ita über -den Manteldes Motorgehäuses i hinweg, durch das nicht dargestellte, filterfreie Lagerschild am anderen Motorende aus. geblasen wird. Dieses Lagerschild weist ringförmige Öffnungen zum Ausblasen der als Kühlluft dienenden Überschüssigen Druckluft auf. Der Aden Stator tragende Motorteil ist lösbar im Motorgehäuse befestigt.In the -'L \ lot-or-housing i is an electric motor by means of desolate, bearing 2 stored, on the extended shaft 3 of the eccentric 4 for actuating the compressor 5 and Idas fan wheel 6 are attached. In front of the fan wheel 6 is Ida's filter 7 in arranged on the housing wall, which can be removed by means of the handle 8. The through, that Filter 7 with its air-guiding device g the fan wheel.6 is supplied air. , compressed by the fan wheel and as pre-compressed air to the compressor 5 supplied, while the excess compressed air through the annular channel ita over the casing of the motor housing i, through the filter-free, not shown End shield at the other end of the motor. is blown. This end shield has an annular shape Openings for blowing out the excess compressed air serving as cooling air. The motor part carrying the stator is detachably fastened in the motor housing.

Die Fig. 2 zeigt einen Blick auf den Schalter i i zum Einschalten des Elektromotors. Das Schaltbrett trägt außerdem eine Schlitzschraube 12 mit dem Schlitz 13, der auf .die eingeschaltete Spannungszahl hinweist und :den Bedienenden bei der Einschaltung des Motors an die Einschaltung der richtigen Spannung erinnert. Wenn die Schlitzschraube mit idem Betätigungsorgan für den Spannungsumschalter der Wicklung gekuppelt ist, ist es durch Verdrehender Schlitzschraube auf eine andere Spannungszahl möglich, den Tragkompressor mittels der Schlitzschraube auf unterschiedliche Spannungen umzuschalten.Fig. 2 shows a view of the switch ii for switching on the electric motor. The switchboard also has a slotted screw 12 with the slot 13, which indicates the switched on voltage number and: reminds the operator to switch on the correct voltage when switching on the motor. If the slotted screw is coupled to the actuator for the voltage changeover switch of the winding, it is possible to switch the portable compressor to different voltages by turning the slotted screw to a different voltage.
