Description

Bekannt sind Elektromotoren mit einem sogenannten, zwischen dem Ständer und dem Läufer befindlichen Spaltrohr. Derartige Elektromotoren werden zum Antrieb von Tiefbrunnenpumpen und ähnlichen Apparaten bevorzugt, und zwar besonders dann, wenn das Motorinnere dem Angriff von Flüssigkeiten ausgesetzt ist. Es ist ferner bekannt, das Spaltrohr an den Zähnen des Ständerblechpaketes ίο schwächer auszuführen als im übrigen. Es entstehen aber Schwierigkeiten beim sitzgerechten Zusammenbau des Ständerblechpaketes mit einem vorher fertiggestellten Spaltrohr von verschiedener Wandstärke dieser Art.Are known electric motors with a so-called, between the stand and the Can located in the rotor. Such electric motors are used to drive deep well pumps and similar devices preferred, especially when the interior of the engine is exposed to attack by liquids is exposed. It is also known that the can on the teeth of the stator core ίο weaker to perform than the rest. However, difficulties arise when it comes to sitting properly Assembly of the stator core with a previously completed can of various wall thicknesses this kind.

Gemäß der Erfindung werden diese Schwierigkeiten dadurch vermindert, daß man ein solches Spaltrohr in Verbindung mit einem zähneweise in Paketsektoren unterteilten Ständerblechpaket verwendet.According to the invention, these difficulties are reduced by having a such a can in connection with a tooth-wise subdivided into packet sectors Stator core used.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Fig. ι zeigt einen Längsschnitt durch den Motor mit dem Spaltrohr gemäß der Erfindung, Fig. Ι shows a longitudinal section through the motor with the can according to the invention,

Fig. 2 einen Längsschnitt durch das Spaltrohr undFig. 2 shows a longitudinal section through the can and

Fig. 3 einen Schnitt durch das Spaltrohr nach der Linie III-III der Fig. 2.
3P Um... das Spaltrohr 2 herum, das an denFIG. 3 shows a section through the can along the line III-III in FIG. 2.
3P Around ... the can 2 attached to the

Zähnen des Ständerblechpaketes 3, wie bei 4 angedeutet ist, sehr dünn ausgebildet ist, während es z. B. an den Nuten eine größere Stärke 5 hat, ist das Ständerblechpaket 3, zähneweise in Blechpaketsektoren unterteilt, herumgebaut. Letzteres ist an sich bereits Gegenstand eines älteren Vorschlages. Die gebildeten Stege 5 des Spaltrohres dienen einerseits in bekannter Weise als Abschlußleisten für die Nuten sowie zur Versteifung des Spaltrohres und andererseits zum Halten der Ständerwicklung 6. Der Läufer des Motors ist mit ι bezeichnet.Teeth of the stator core 3, as indicated at 4, is very thin, while it z. B. has a greater thickness 5 at the grooves, the stator core is 3, Tooth-wise divided into laminated core sectors, built around. The latter is in itself already Subject of an older proposal. The formed webs 5 of the can serve on the one hand in a known manner as end strips for the grooves and for stiffening the can and on the other hand to hold the stator winding 6. The rotor of the motor is denoted by ι.
