Auf einem solchen Flächenteil läßt sich die Spule insbesondere in Form einer oder mehrerer übereinanderliegender Spiralen besonders einfach, z. B. durch Aufdrucken befestigen. Hierbei wird eine besonders platzsparende Bauweise erreicht und ein Montieren ist besonders leicht durchführbar.The coil can be placed on such a surface part especially in the form of one or more superimposed spirals particularly simple, e.g. B. fasten by printing.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen:An embodiment of the invention is in the Drawings shown and will be described in more detail below described. Show it:
Fig. 1 Ein mehrlagiges Flächenteil in der Draufsicht. Fig. 1 A multi-layer surface part in plan view.
Fig. 2 Das Flächenteil nach Fig. 1 in einer Seiten ansicht. Fig. 2 The flat part of FIG. 1 in a side view.
Fig. 3 Einzelne Lagen des Flächenteils. Fig. 3 individual layers of the surface part.
Fig. 4 Einen achsialen Schnitt durch einen Stator eines Elektromotors mit an der Wickelkopfkappe kopfseitig befestigtem Flächenteil und Fig. 4 shows an axial section through a stator of an electric motor with the surface part attached to the end cap on the end of the winding head and
Fig. 5 eine Stirnansicht des Motorenstators mit befestigtem Flächenteil. Fig. 5 is an end view of the motor stator with a fixed surface part.
Der elektrische Antriebsmotor einer Kreiselpumpe weist einen Stator 1 auf, dessen Wicklungen 2 zu beiden Stirnseiten durch Kappen 3a, 3b abgedeckt sind. An der, der nicht dargestellten Pumpe zugewandten Wickelkopfkappe ist ein Flächenteil 4 befestigt, das aus einer starren oder flexiblen Scheibe oder einer Folie mit mehreren Lagen besteht. Das Flächenteil 4 ist durch eine Schnappverbindung mit der Kappe 3a verbunden. Hierzu ragen an der Kunststoffkappe 3 nach außen Zapfen 5 vor, die Öffnungen 6 im Flächenteil 4 durchdringen.The electric drive motor of a centrifugal pump has a stator 1 , the windings 2 of which are covered on both ends by caps 3 a, 3 b. On the winding head cap facing the pump, not shown, a surface part 4 is attached, which consists of a rigid or flexible disk or a film with several layers. The surface part 4 is connected by a snap connection to the cap 3 a. For this purpose, pins 5 protrude outward from the plastic cap 3 and penetrate the openings 6 in the flat part 4 .
Das Flächenteil 4 ist im Ausführungsbeispiel teilringförmig und insbesondere U-förmig bzw. hufeisenförmig. Es kann aber auch V-förmig sein. Ferner kann eine U-Form auch mehr oder weniger rechtwinklig abgebogene Ecken besitzen, die die Schenkel des U′s mit der Basis verbinden.The surface part 4 is in the embodiment part-ring-shaped and in particular U-shaped or horseshoe-shaped. But it can also be V-shaped. Furthermore, a U-shape can also have more or less bent corners that connect the legs of the U's to the base.
Das Flächenteil besteht aus mehreren Lagen 7 bis 10, die in Fig. 3 dargestellt sind. Hierbei bildet die Lage 7 die obere Lage, die Lagen 8, 9 mittlere Zwischenlagen und die Lage 10 eine Bodenlage, die an der Wickelkopfkappe 3a anliegt. Mindestens auf eine dieser Lagen, im Ausführungsbeispiel auf allen dieser Lagen, ist auf diametral gegenüberliegenden Seiten jeweils eine Spirale 11 aus leitendem Material, insbesondere aus Metall aufgeätzt und/oder aufgedruckt, die die Funktion einer Spule übernimmt und damit als Sensor wirkt. Die Funktion dieses Sensors wird wesentlich verbessert, wenn mehrere dieser Spiralen übereinander angeordnet sind, wie dies in Fig. 3 dargestellt ist. Hier sind auf jeder der Lagen 7 bis 10 Spiralen aufgedruckt. Alternativ können aber auch die Spiralen auf andere Weise hergestellt und befestigt werden.The surface part consists of several layers 7 to 10 , which are shown in Fig. 3. Here, the layer 7 constitutes the upper layer, the layers 8, 9 mean the intermediate layers and the layer 10 abuts a bottom layer attached to the winding head cap 3 a. At least on one of these layers, in the exemplary embodiment on all of these layers, a spiral 11 made of conductive material, in particular made of metal, is etched and / or printed on diametrically opposite sides, which takes over the function of a coil and thus acts as a sensor. The function of this sensor is significantly improved if several of these spirals are arranged one above the other, as shown in FIG. 3. Here, 7 to 10 spirals are printed on each of the layers. Alternatively, the spirals can also be produced and attached in a different way.
Die Lagen 7 bis 10 sind übereinander befestigt und bilden damit das Flächenteil wie es in den Fig. 1, 2, 4 und 5 dargestellt ist. Am Flächenteil 4 ist noch bedarfsweise ein Temperatursensor 12 auf der der Pumpe zugewandten Seite und seitlich ein Anschlußkabel 13 befestigt. Das Anschlußkabel wird vorzugsweise seitlich des Stators zur gegenüberliegenden Wickelkopfkappe 3b geführt und ist an eine Steckerleiste 14 angeschlossen. The layers 7 to 10 are fastened one above the other and thus form the flat part as shown in FIGS. 1, 2, 4 and 5. If necessary, a temperature sensor 12 is also attached to the surface part 4 on the side facing the pump and a connecting cable 13 is attached to the side. The connecting cable is preferably led laterally of the stator to the opposite end cap 3 b and is connected to a plug connector 14 .
Die einzelnen übereinander liegenden Spiralen 11 der Lagen 7 bis 10 sind miteinander elektrisch verbunden und die äußerste Spirale der Lage 7 ist durch eine Isolierung 15 insbesondere durch eine Isolierfolie oben bedeckt. Der Temperatursensor steht über Lage 7 hervor, um beim Lagerschild (Abtrennung zum Pumpenmedium) einen Anpreßdruck zu bewirken (= besserer thermischer Übergang). Der Temperatursensor selbst liegt im eingebauten Zustand in einer Ausstanzung des "Flächenteils". Der Temperatursensor 12 liegt oben auf der obersten Lage 7 auf und kann zumindest zum Teil in eine Vertiefung des Flächenteils eingedrückt sein. Mindestens eine der Lagen 7 bis 10 besteht vorzugsweise aus einer Leiterplatte.The individual spirals 11 of the layers 7 to 10 lying one above the other are electrically connected to one another and the outermost spiral of the layer 7 is covered at the top by insulation 15, in particular by an insulating film. The temperature sensor protrudes above layer 7 in order to cause a contact pressure on the end shield (separation from the pump medium) (= better thermal transition). When installed, the temperature sensor itself lies in a punched-out area. The temperature sensor 12 lies on top of the uppermost layer 7 and can at least partially be pressed into a recess in the surface part. At least one of the layers 7 to 10 preferably consists of a printed circuit board.
Das am Stator 1 befestigte Flächenteil sehr geringer Bauhöhe liegt damit im befestigten Zustand zwischen dem Stator und dem Lagerschild der Pumpe und damit sehr nahe dem Pumpenlaufrad, das ein oder zwei Magnete trägt, die beim Vorbeifahren an den Spiralen 11 bzw. den Spulen Spannungen und damit Ströme erzeugen, die von einer Elektronik ausgewertet werden, die als Modul an der Pumpe befestigt ist. Hierdurch kann die Drehzahl der Pumpe exakt bestimmt werden.The surface part fastened to the stator 1 of very low height is thus in the fastened state between the stator and the end shield of the pump and thus very close to the pump impeller, which carries one or two magnets, which, when passing the spirals 11 or the coils, tension and thus Generate currents that are evaluated by electronics that are attached to the pump as a module. This enables the speed of the pump to be precisely determined.
Auswertung Temperatur: Sensor liegt in Reihe zu den Spulen, daher weiterhin nur zwei Verbindungsleitungen 13.Temperature evaluation: sensor is in series with the coils, therefore only two connecting lines 13 .
