Abstract
Description
Die Erfindung betrifft eine Anordnung zum Verbinden der Enden einer Statorwicklung von Elektromotoren unter Verwendung einer an einem Ende des Stators angeordneten, aus Isoliermaterial bestehenden, ringförmigen Leiterplatte, die mit aufgedruckten Kupferleiterbahnen versehen ist, die die Verbindungselemente zwischen den Wicklungsenden einerseits und den Wicklungsenden und dem Motoranschlußkabe! andererseits bilden.The invention relates to an arrangement for connecting the ends of a stator winding of electric motors using a ring-shaped one made of insulating material and arranged at one end of the stator Printed circuit board with printed copper conductor tracks that form the connecting elements between the winding ends on the one hand and the winding ends and the motor connection cable! on the other hand form.
Es ist bekannt, zum Verbinden der Spulen von Statorwicklungen elektrischer Maschinen, an einem Ende des Stators einen Schaltring vorzusehen, der Leiterstücke aufweist, die die Verbindungselemente zwischen den Wicklungsenden und dem Anschlußkabel bilden. Die Leiterstücke werden mit einem Isolierschlauch überzogen, in eine Gießform eingelegt und mit Ausgußmasse z. B. einem aushärtbaren Epoxydharz ausgefüllt (DE-Gbm 19 62 096).It is known to connect the coils of stator windings of electrical machines to one Provide a switching ring at the end of the stator, which has conductor pieces that form the connecting elements between the winding ends and the connecting cable. The conductor pieces are covered with an insulating tube coated, placed in a mold and with pouring compound z. B. a curable epoxy resin completed (DE-Gbm 19 62 096).
Die DE-AS 11 62 467 befaßt sich mit einem Verfahren zum Herstellen einer Reihenwicklung für Anker von Wechselstromerzeugern aller Art, und zwar vor allem mit solchen, die mit einem aus Dioden bestehenden Gleichrichter versehen sind. Auf einem als Verbindungskörper für die Spulenenden dienenden Isolierhalter werden Leiterplättchen eingeformt. Die Wicklungsenden können untereinander bzw. mit dem Anschluükabel auch mittels aufgedruckter Verbindungsteile verbunden werden.DE-AS 11 62 467 deals with a method for the production of a series winding for armatures of all kinds of alternating current generators, in particular with those that are provided with a rectifier consisting of diodes. On an insulating holder that serves as a connecting body for the coil ends circuit boards are molded in. The winding ends can be connected to each other or to the connection cable can also be connected by means of printed connecting parts.
Nach der DE-PS 19 22 860 wird die Aufgabe, bei einer elektrischen Maschine mit einem Magnetpole aufweisenden Läufer und einem nutenlosen Ständer bei zylindrischem Luftspalt eine möglichst geringe axialeAccording to DE-PS 19 22 860, the task is, in an electrical machine with a magnetic pole Rotor and a slotless stator with a cylindrical air gap the smallest possible axial
lü Baulänge zu erreichen, dadurch gelöst, daß an den beiden Stirnseiten des zylindrischen Ständers ringförmige, mit Leitern bestückte Platten befestigt sind, und daß die freien Enden der leitenden Streifen zur Vervollständigung der Windungen der Ständerwicklung mit den Leitern verbunden sind.lü overall length to be achieved by the fact that the both end faces of the cylindrical stator ring-shaped, equipped with conductors plates are attached, and that the free ends of the conductive strips to complete the turns of the stator winding with the Ladders are connected.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, bei einem Außenläufermotor, dessen Statorwicklung
aus drahtgewickelten Spulen besteht und über die Stirnseiten des Blechpaketes überstehende Wicklungsköpfe
aufweist, eine raumsparende Anordnung für die Verbindung zwischen den Wicklungsenden einerseits
und den Wicklungsenden und dem Motorenanschlußkabel andererseits vorzusehen.
Gelöst wird die gestellte Aufgabe dadurch, daß zum Herstellen dieser Verbindung bei einem Außenläufermotor,
dessen Statorwicklung aus drahtgewickelten Spulen besteht und über die Stirnseite des Blechpaketes
überstehende Wickelköpfe aufweist, die Leiterplatte am Kragen einer an der Stirnseite des StatorblechpaketsIn contrast, the invention is based on the object of providing a space-saving arrangement for the connection between the winding ends on the one hand and the winding ends and the motor connection cable on the other hand in an external rotor motor whose stator winding consists of wire-wound coils and has winding heads protruding over the end faces of the laminated core.
The object is achieved in that to establish this connection in an external rotor motor whose stator winding consists of wire-wound coils and has overhanging end windings, the circuit board on the collar of one on the end face of the stator core
anliegenden Isolierstoffscheibe befestigt ist und daß die aufgedruckten Kupferleiterbahnen mit Schlitzen für die Verbindung mit den Wicklungsenden versehen sind.adjacent insulating disc is attached and that the printed copper conductor tracks with slots for the Connection with the winding ends are provided.
Damit ergibt sich der Vorteil der Raumeinsparung. Die Gefahr der Windungsschlüsse in der Schaltnut entfällt, weil der Motoranschluß nicht mehr in der Wickelnut geführt wird. Durch die gedruckte Schaltung erhält das Ansch'.ußkabel eine gute Zugentlastung.This has the advantage of saving space. The risk of winding shorts in the switching groove not applicable because the motor connection is no longer guided in the winding groove. Through the printed circuit the connection cable receives good strain relief.

Printed copper conductor tracks 6 are provided with slots 3 for connection to the winding ends.
Die Anordnung der Kupferleiterbahnen 6 auf der gedruckten Schaltung richtet sich nach der Schaltungsart des Elektromotors (Nutzahl, Polzahl usw.). The arrangement of the copper conductor tracks 6 on the printed circuit depends on the type of circuit of the electric motor (number of slots, number of poles, etc.).
Die Leiterbahnen 6 werden an einer Stelle zusammengeführt, an der das Motoranschlußkabel 4 angelötet ist.The conductor tracks 6 are brought together at a point where the motor connection cable 4 is soldered is.
Einige Leiterbahnen 6 weisen nach außen zum Rand der Leiterplatte 1 hin ragende Stege 7 auf.Some conductor tracks 6 have webs 7 projecting outward toward the edge of the circuit board 1.
