Mit einer Wicklung versehenes, durch ein an sich bekanntes Wickelverfahren hergestelltes und flachgepresstes Blechpaket
Um isoliert geblätterte Wendepolkerne zu erzeugen war es bisher üblich, einzelne gestanzte Bleche (mit Papier oder Lack isoliert) zu schichten und mit Nieten, die durch Rohre und Kappen isoliert wurden, zu verbinden. Eine weitere Fertigungsmöglichkeit besteht darin, diese gestanzten Bleche durch Klebung zu verbinden.
Die Erfindung betrifft ein mit einer Wicklung versehenes, durch ein an sich bekanntes Wickelverfahren hergestelltes und flach gepresstes Blechpaket, insbesondere einen Wendepol, bei dem erfindungsgemäss das Blechpaket zusammen mit der auf das Paket aufgebrachten Wicklung, insbesondere der Polspule einer Giessharztränkung und Aushärtung, unterzogen ist, wodurch es einen mechanischen Bearbeitungen standhaltenden rüttelfesten Körper bildet.
Aus der österr. Patentschrift Nr. 120335 ist zwar ein als Ringkern gewickelter und flachgedrückter Transformatorkern bekanntgeworden, jedoch ist in dieser Patentschrift nicht angegeben, in welcher
EMI1.1
In der deutschen Auslegeschrift 1155527 ist in allgemeiner Art ein Verfahren beschrieben, Polspulen auf Polkörpern zu vergiessen. Ein Vergiessvorgang ist jedoch nicht einem Tränkvorgang gleichzusetzen. Der Tränkvorgang beruht hauptsächlich auf dem vollständigen Füllen der Hohlräume und Spalten durch Kapillarwirkung, während der Giessvorgang rein oberflächlich erfolgt.
Der Vorteil des erfindungsgemässen Verfahrens liegt in der Zeitersparnis bei der Herstellung. Es fällt das Stanzen und Nieten weg. Bei den bereits bekannten aus Blechband gewickelten Kernen für Transformatoren oder für Spulen von elektrischen Maschinen handelt es sich um Ringkerne, die in der genannten Form verbleiben, während bei den Kernen für Wendepole das gewickelte Blechpaket zu einem kompakten Kern gepresst und zusammen mit der Wicklung verfestigt wird.
Das erfindungsgemässe Blechpaket ist in den schematischen Zeichnungen dargestellt, wobei Fig. l eine Ansicht, teilweise im Schnitt, und Fig. 2 eine Aufsicht zeigen. Fig. 3a und 3b zeigen im Querschnitt und in Ansicht den aus dem Bandmaterial gewickelten Wendepolkern. In sämtlichen Figuren ist mit das Bandmaterial, mit--2--der flache Dorn des Wendepolkernes und mit--3-die Wicklung bezeichnet.

Laminated core which is provided with a winding and is produced by a known winding process and is pressed flat
In order to produce insulated peeled reversible pole cores, it has been customary up to now to layer individual stamped sheets (insulated with paper or lacquer) and to connect them with rivets that are insulated by tubes and caps. Another manufacturing option is to connect these punched sheets by gluing.
The invention relates to a laminated core provided with a winding, produced by a known winding process and pressed flat, in particular a reversible pole, in which, according to the invention, the laminated core, together with the winding applied to the packet, in particular the pole coil, is subjected to a cast resin impregnation and curing, whereby it forms a vibration-proof body that can withstand mechanical processing.
A transformer core wound as a toroidal core and flattened is known from Austrian patent specification No. 120335, but this patent specification does not specify in which
EMI1.1
In the German Auslegeschrift 1155527 a method is described in a general way to cast pole coils on pole bodies. However, a casting process is not to be equated with a soaking process. The impregnation process is mainly based on the complete filling of the cavities and crevices by capillary action, while the pouring process takes place purely on the surface.
The advantage of the method according to the invention lies in the saving of time during manufacture. There is no punching or riveting. The already known cores for transformers or for coils of electrical machines, which are wound from sheet metal strip, are toroidal cores that remain in the form mentioned, while in the case of the cores for reversible poles, the wound laminated core is pressed into a compact core and solidified together with the winding .
The laminated core according to the invention is shown in the schematic drawings, FIG. 1 showing a view, partly in section, and FIG. 2 showing a plan view. 3a and 3b show, in cross section and in a view, the reversible pole core wound from the strip material. In all of the figures, the strip material is denoted by, the flat mandrel of the reversible pole core is denoted by -2, and the winding is denoted by -3.
