Bei elektrischen Maschinen und Motoren mit Kurzschlußankern, bei welchen die Bleche zusammenhaltende .-Preßplatten zugleich als Kurzschlußstücke für die am Umfange ange-5 ordneten Kupferstäbe dienen und mit diesen fest verlötet sind, besteht der Übelstand, daß die Lötstellen bei Erwärmung infolge des Bestrebens der Kupferstäbe, sich anders auszudehnen als die schmiedeeisernen Bleche,In electrical machines and motors with short-circuit armatures, in which the metal sheets holding together arranged copper rods and are firmly soldered to these, there is the disadvantage that the soldering points when heated due to the tendency of the copper rods to expand differently than the wrought iron sheets,
ίο sehr stark beansprucht und häufig zerstört werden, sobald der zur Fortleitung des Stromes erforderliche gute Kontakt zwischen den Stäben und dem Kurzschlußstück verloren geht.ίο very heavily used and often destroyed as soon as the necessary good contact between the rods and the short-circuit piece is lost.
Nach vorliegender Neuerung soll dieser Übelstand dadurch beseitigt werden, daß nur das eine Kurzschlußstück a 7Mva Zusammenpressen der Bleche verwendet wird, während auf der anderen Seite eine besondere Preßplatte b, durch welche die Stäbe lose hindurchgeführt werden, vorgesehen ist. Auf der verlängerten Nabe der Preßplatte ist, in achsialer Richtung verschiebbar, das Kurzschlußstück c angeordnet, welches nunmehr ohne weiteres den durch die Erwärmung hervorgerufenen Bewegungen der Kupferstäbe folgen kann, ohne daß dabei eine besondere Beanspruchung der Lötstellen eintritt.According to the present innovation, this drawback is to be eliminated by using only one short-circuit piece a 7Mva pressing the sheets together, while on the other side a special pressing plate b, through which the rods are loosely passed, is provided. The short-circuit piece c is arranged on the elongated hub of the press plate, displaceable in the axial direction, which can now easily follow the movements of the copper rods caused by the heating without causing any particular stress on the soldering points.
