Description
Die Erfindung bezieht sich auf ein Verfahren zur Tränkung von aus Blechen geschichteten Paketen für elektrische Maschinen und Geräte, insbesondere Ständerblechpakete für gehäuselose Motoren, durch Eintauchen der Pakete in ein Tränkmittel, das nach Aushärtung die geschichteten Bleche miteinander verklebt.The invention relates to a method for impregnating packets layered from sheet metal for electrical machines and devices, in particular stator core assemblies for frameless motors Immersing the packets in an impregnating agent, which, after hardening, binds the laminated sheets together glued.
Bei einem bekannten Verfahren der eingangs genannten Art (britische Patentschrift 1 060 705) wird das aus Blechen geschichtete Paket aus dem Tränkmittelbad gezogen, danach wird in einem weiteren Arbeitsgang überschüssiges Tränkmittelmaterial — beispielsweise durch Wegblasen— entfernt und anschließend das verbleibende Tränkmittel beim Durchlaufen durch einen Trocknungsofen verfestigt.In a known method of the type mentioned (British patent specification 1 060 705) the stacked sheet-metal package is pulled out of the impregnating agent bath, after which it is put into another In the process, excess impregnating agent material is removed - for example by blowing it away - and then the remaining impregnating agent solidifies as it passes through a drying oven.
Nach einem weiteren bekannten Tränkungsverfahren werden die mittels einer besonderen Vorrichtung
auf Distanz gehaltenen Bleche aus einem Tauchbad ohne Beachtung besonderer Maßgaben zusammen
herausgezogen, aufeinandergedrückt und bei anschließender Trocknung des Tränkmittels miteinander
verklebt. Zumindest zur Entfernung der beim Zusammendrücken entstehenden Tränkmittelüberstände
muß ein derartig verklebtes Blechpaket einer zusätzlichen Nachbearbeitung unterzogen werden,
um beispielsweise den Rotor fluchtend und unter allseitiger Einhaltung des vorgeschriebenen Luftspalts
in die Ständerbohrung des aus Blechen geschichteten Ständerblcchpaketes einbringen zu können,
ίο Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zur Tränkung von aus Blechen geschichteten
Paketen für elektrische Maschinen und Geräte, insbesondere Ständerblechpakete für gehäuselose
Motoren, durch Eintauchen der Pakete in ein Tränkmittel zu schaffen, das wirtschaftlich vertretbar
ist und den Arbeitsaufwand beim Zusammenbau ein solches Blechpaket enthaltenden Motors im Vergleich
zu dem bekannten Verfahren weiter mindert.According to a further known impregnation process, the metal sheets, which are kept at a distance by means of a special device, are pulled together from an immersion bath without observing any special requirements, pressed onto one another and glued to one another when the impregnating agent is subsequently dried. At least to remove the impregnating agent protruding from compression, such a glued laminated core must be subjected to additional post-processing in order, for example, to be able to insert the rotor into the stator bore in the stator core, which is layered from sheet metal, in alignment with the prescribed air gap on all sides,
It is therefore the object of the present invention to provide a method for impregnating stacks of laminated sheets for electrical machines and devices, in particular stator laminated stacks for frameless motors, by immersing the packages in an impregnating agent that is economically justifiable and reduces the workload during assembly such a laminated core containing engine is further reduced compared to the known method.
Die Lösung der gestellten Aufgabe ist erfindungsgemäß dadurch möglich, daß die Austauchgeschwindigkeiten der Blechpakete aus dem Tränkmittel niedriger als die Fließgeschwindigkeit des Tränkmittels unmittelbar oberhalb der Austauchebene gehalten wird, derart, daß die Schichten an der Oberfläche, insbesondere in der Ständerbohrung, eine im wesentlichen gleichmäßige Stärke annehmen. Damit wird erreicht, daß das Blechpaket verfestigt und dabei gleichzeitig von einer gleichmäßigen Tränkmittelschichtdicke überzogen wird, ohne daß zusätzliche Arbeitsgänge nach dem Tränken, beispielsweise für eine Nachbearbeitung und für eine Entfernunc von Tropfen, erforderlich sind.The object is achieved according to the invention in that the exchange speeds of the sheet metal stacks from the impregnating agent lower than the flow rate of the impregnating agent is held immediately above the exchange level, in such a way that the layers on the surface, especially in the stator bore, assume a substantially uniform thickness. So that will achieves that the laminated core solidifies and at the same time of a uniform thickness of the impregnating agent is coated without additional operations after soaking, for example for post-processing and for removal of drops are required.
Durch Wahl eines bestimmten Tränkmittels, beispielsweise hinsichtlich einer bestimmten Viskosität oder einer bestimmten Temperatur, läßt sich in vorteilhafter Weise die Schichtdicke beeinflussen, so daß die Schichten insbesondere den erforderlichen Isolationswiderstand aufweisen. Nachdem man nach diesen Gesichtspunkten das Tränkmittel ausgewählt hat, kann zweckmäßigerweise in der Praxis die genaue, optimale Austauchgeschwindigkeit im Sinn der erfindungsgemäßen Lehre im Einzelfall experimentell ermittelt werden.By choosing a specific impregnating agent, for example with regard to a specific viscosity or a certain temperature, the layer thickness can be influenced in an advantageous manner, so that the layers in particular have the required insulation resistance. After going after these Has chosen the impregnating agent, in practice the exact, optimal exchange speed in the sense of the teaching according to the invention determined experimentally in individual cases will.
Nach einer besonderen Ausgestaltung der Erfindung wird als Tränkmittel Polyesterharz verwendet, das unter anderem in ausreichender Menge zwischen die einzelnen Bleche einzudringen vermag. Die einzelnen Bleche werden in vorteilhafter Weise vor dem Tauchen in an sich bekannter Weise zu einem Paket geschweißt bzw. genietet oder vor dem Tauchen zu einem Paket geklammert, wobei die Klammern nach dem Tauchen und Aushärten, z. B. durch Abschlagen, entfernt werden. Da die Festigkeit im wesentlichen durch das Tränkmittel erzielt wird, ist der Aufwand für Klammern, Nieten und Schweißen der geschichteten Blechpakete gering. Es ist zweckmäßig, die Blechpakete vor dem Tauchen zu entgraten. In Fällen, in denen eine Verfestigung der aus Blechen geschichteten Pakete vor dem Wickeln nicht erforde rl ich ist (keine mechanische Bearbeitung der Pakete vor dem Wickeln), kann das Verfahren erst nach dem Anwickeln Anwendung finden.According to a particular embodiment of the invention , polyester resin is used as the impregnating agent, which, among other things, is able to penetrate between the individual sheets in sufficient quantities. The individual sheets are advantageously welded or riveted to form a package in a known manner prior to dipping or clamped to form a package before dipping, the brackets after dipping and hardening, e.g. B. by knocking off. Since the strength is essentially achieved by the impregnating agent, the effort for staples, rivets and welding of the layered laminated cores is low. It is advisable to deburr the sheet metal stacks before diving. In cases in which it is not necessary to solidify the laminated sheets before winding (no mechanical processing of the packages before winding), the process can only be used after the winding has started.
