Abstract

The housing (10) is made of aluminium plate which is shaped by cold drawing and has a wall thickness of 0.5 to 1.2 mm., pref. 0.8 mm. A self-contained pot (8) is attached to the housing, esp. to its flange (11). An opening on one side of the housing, esp. on its top, accepts a plastic insert. A clamp box and/or electronic unit is or are mounted on the insert. Alternatively, a box contg. the clamp box and/or electronic unit can be placed with its underside in the opening.

Description

Die Erfindung betrifft ein Gehäuse eines Elektromotors, insbesondere für eine Motorkreiselpumpe, wobei das Gehäuse aus Aluminium gefertigt ist.The invention relates to a housing of an electric motor, especially for a motor centrifugal pump, the housing is made of aluminum.

Es ist bekannt, das Gehäuse eines Elektromotors aus Aluminiumdruckguß herzustellen. Dieses Herstellungsver­ fahren ist aufwendig, benötigt verhältnismäßig viel Material und erfordert eine spanabhebende Bearbeitung.It is known to make the housing of an electric motor To manufacture die-cast aluminum. This manufacturing ver driving is complex, requires a relatively large amount Material and requires machining.

Aufgabe der Erfindung ist es, ein Motorgehäuse aus Aluminium so zu verbessern, daß es bei einfacher Herstellung wenig Material erfordert.The object of the invention is to develop a motor housing To improve aluminum so that it is easier Manufacturing requires little material.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse aus Aluminiumblech besteht, das durch Tiefziehen in seine Form gebracht wurde.This object is achieved in that the housing is made of aluminum sheet that through Thermoforming was brought into its shape.

Ein Motorgehäuse aus tiefgezogenem Aluminiumblech ist kostengünstig herstellbar, führt zu einer erheblichen Materialreduzierung und erfordert keine spanabhebende Bearbeitung. Hierbei wird eine sehr gute Wärmeleitfähigkeit erreicht.A motor housing is made of deep-drawn aluminum sheet inexpensive to produce, leads to a considerable Material reduction and does not require machining  Editing. This will be a very good one Thermal conductivity reached.

Besonders vorteilhaft ist hierbei, wenn das Aluminiumblech eine Wandstärke von 0,5 bis 1,2 mm, vorzugsweise von 0,8 mm aufweist. Von größtem Vorteil ist es, wenn am Gehäuse, insbesondere an seinem Flansch ein selbsttragender Spalttopf befestigt ist.It is particularly advantageous if the Aluminum sheet a wall thickness of 0.5 to 1.2 mm, preferably of 0.8 mm. Is of the greatest advantage it when on the housing, especially on its flange self-supporting can is attached.

Zur thermischen Isolierung der Elektronik wird vorgeschlagen, daß das Gehäuse an seiner Seite, insbesondere Oberseite eine Ausnehmung aufweist, in der ein Kunststoffeinsatz einliegt, auf dem der Klemmenkasten und/oder ein Elektronik enthaltener Kasten angeordnet ist. Alternativ wird hierzu vorgeschlagen, daß das Gehäuse an seiner Seite, insbesondere Oberseite eine Ausnehmung aufweist, in der ein Klemmenkasten und/oder bin Elektronik enthaltener Kasten mit seiner Unterseite einliegt.For thermal insulation of the electronics suggested that the case by his side, especially top has a recess in which there is a plastic insert on which the terminal box and / or a box containing electronics is arranged is. Alternatively, it is proposed that the Housing on its side, especially top one Has recess in which a terminal box and / or am electronics contained box with its bottom lies in.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zeigen:Two embodiments of the invention are in the Drawing shown and are closer below described. Show it:

Fig. 1 einen axialen Schnitt durch den Elektro­ motor einer Kreiselpumpe in einer ersten Ausführung und Fig. 1 shows an axial section through the electric motor of a centrifugal pump in a first embodiment and

Fig. 2 einen Ausschnitt aus Fig. 1 in einer zweiten Ausführung. Fig. 2 shows a detail from Fig. 1 in a second embodiment.

Ein Elektromotor 1 weist einen Stator 2 mit Wicklungen 3 und einen Rotor 4 auf, der auf einer Welle 5 befestigt ist, die in zwei Lagern 6, 7 gehalten ist. An electric motor 1 has a stator 2 with windings 3 and a rotor 4 which is fastened on a shaft 5 which is held in two bearings 6 , 7 .

Zwischen Stator 2 und Rotor 4 ist ein Spalttopf 8 angeordnet, der einen Flansch 9 aufweist. Der Flansch 9 bildet die Trennwand zwischen dem Motor 1 und einer am Motor angeflanschten Kreiselpumpe, deren Laufrad auf einem Ende der Welle 5 befestigt ist.A can 8 is arranged between the stator 2 and the rotor 4 and has a flange 9 . The flange 9 forms the partition between the motor 1 and a centrifugal pump flanged to the motor, the impeller of which is attached to one end of the shaft 5 .

Das Gehäuse 10 des Motors 1 ist aus Aluminiumblech tiefgezogen, das eine Stärke von 0,5 bis 1,2 mm, vorzugsweise von 0,8 mm aufweist. Das topfförmige Motorgehäuse 10 bildet auf der der Pumpe zugewandten Seite einen Flansch 11, an dem der Flansch 9 des Spalttopfes 8 und insbesondere auch der nicht dargestellte Flansch des Pumpengehäuses befestigt ist.The housing 10 of the motor 1 is deep-drawn from aluminum sheet, which has a thickness of 0.5 to 1.2 mm, preferably 0.8 mm. The cup-shaped motor housing 10 forms on the side facing the pump a flange 11 to which the flange 9 of the containment shell 8 and in particular also the flange (not shown) of the pump housing is fastened.

In dem etwa zylindrischen seitlichen Mantel 12 des Motorgehäuses 10 ist eine, vorzugsweise rechtwinklige Öffnung 13 eingebracht, in der formschlüssig, insbesondere reibschlüssig ein plattenförmiger Kunststoffeinsatz 14 füllend bzw. abschließend und abdichtend einliegt. Auf dem Einsatz 14 ist ein Klemmenkasten 15 aus Kunststoff befestigt, der elektronische Bauteile zur Steuerung der Pumpe aufweist.In the approximately cylindrical lateral casing 12 of the motor housing 10 , a, preferably rectangular, opening 13 is introduced, in which a plate-shaped plastic insert 14 lies in a form-fitting, in particular a friction-fitting manner, filling or closing and sealing. A plastic terminal box 15 is attached to the insert 14 and has electronic components for controlling the pump.

Ein steckerförmiger Teil 16 steht an der Unterseite des Klemmenkastens 15 vor und reicht durch eine Öffnung im Einsatz 14 in das Innere des Motors hinein, um Kontakte an der Wicklung 3 zu kontaktieren.A plug-shaped part 16 protrudes on the underside of the terminal box 15 and extends through an opening in the insert 14 into the interior of the motor in order to contact contacts on the winding 3 .

In der in Fig. 2 dargestellten Alternative ist die Öffnung 13 durch die Unterseite des Klemmenkastens 15 ausgefüllt, so daß es eines Kunststoffeinsatzes 14 nicht bedarf.In the alternative shown in FIG. 2, the opening 13 is filled through the underside of the terminal box 15 , so that a plastic insert 14 is not required.
