Abstract
Bei einem Drehstrommotor mit einer Sternschaltung zu Spulensegmenten (25-28) zusammengeschaltet. Die Spulensegmente (25-28) verbinden die Spulen (1-24) untereinander und weisen jeweils eine Verbindung mit den Strängen (U, V, W) auf. Die Aufteilung der Spulen (1-24) auf die Spulensegmente (25-28) führt zu einer Vereinfachung der Fertigung des Drehstrommotors.In a three-phase motor with a star connection to coil segments (25-28) interconnected. The coil segments (25-28) connect the coils (1-24) with each other and each have a connection to the strands (U, V, W). The division of the coils (1-24) on the coil segments (25-28) leads to a simplification of the production of the three-phase motor.
Description
Die Erfindung betrifft einen Drehstrommotor mit einem Rotor und mit einem Stator mit drei sternförmig geschalteten Strängen des Stators, wobei pro Strang eine Anzahl s Spulen in Serie und eine Anzahl p Spulen parallel geschaltet sind.The The invention relates to a three-phase motor with a rotor and with a stator with three stars switched strands of the stator, wherein per strand a number s coils in series and a number of p coils are connected in parallel.
Solche Drehstrommotoren werden häufig in Großserien hergestellt und sind aus der Praxis bekannt. Die Statoren der aus der Praxis bekannten Drehstrommotoren werden als so genannte verteilte Wicklung oder als Einzelzahnspulen hergestellt. Die Verschaltung der Spulen erfolgt in der Regel von Hand oder durch Einziehtechnik. Dies führt jedoch insbesondere bei Großserien zu einem großen fertigungstechnischen Aufwand. Zur Vereinfachung der Verschaltung sind daher Ringsegmente oder Kontaktbrücken bekannt geworden. Dennoch erfordert die Fertigung der bekannten Drehstrommotoren einen sehr großen Aufwand.Such Three-phase motors become common in large series made and are known from practice. The stators of the The practice known three-phase motors are called a so-called distributed winding or manufactured as single tooth coils. The interconnection of the coils usually done by hand or by Einziehtechnik. However, this leads in particular in large series to a big one production engineering effort. To simplify the interconnection Therefore ring segments or contact bridges have become known. Yet requires the production of the known three-phase motors a very huge Effort.
Der Erfindung liegt das Problem zugrunde, einen Drehstrommotor der eingangs genannten Art so zu gestalten, dass er insbesondere in einer Großserie besonders einfach zu fertigen ist.Of the Invention is based on the problem, a three-phase motor of the above be designed so that he especially in a large series especially easy to manufacture.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Spulen des Stators in p Spulensegmenten symmetrisch aufgeteilt sind und dass die Spulensegmente jeweils mit jedem der Stränge verbunden sind.This Problem is inventively characterized solved, that the coils of the stator are divided symmetrically into p coil segments and that the coil segments are each connected to each of the strands are.
Durch diese Gestaltung lassen sich die Spulensegmente einfach als vormontierte Bauteile fertigen. Die Einteilung der parallel geschalteten Spulen in dieselbe Anzahl an Spulensegmenten ermöglicht die einfache Verschaltung der Spulen untereinander. Die Aufteilung des Sternpunktes in p einzelne Sternpunkte ermöglicht die Modularisierung in p Spulensegmente, welche jeweils von allen Strängen angesteuert werden. p entspricht der Anzahl der parallel geschalteten Spulen pro Strang. Eine zusätzliche Sternpunktschiene zur Erzeugung des Sternpunktes wird dank der Erfindung vermieden. Durch die Verbindung jeder der Spulensegmente mit jedem der Stränge wird die Verschaltung der einzelnen Spulen untereinander vervollständigt. Hierdurch gestaltet sich die Fertigung des erfindungsgemäßen Drehstrommotors insbesondere in Großserie besonders einfach. Die Spulen sind so genannte Einzelzahnspulen mit eigenem Spulenkern.By This design allows the coil segments simply as pre-assembled Manufacture components. The division of the parallel coils in the same number of coil segments enables easy interconnection the coils with each other. The division of the star point into p single Star points enabled the modularization in p coil segments, each of which strands be controlled. p corresponds to the number of parallel connected Coils per strand. An additional star point rail to generate the star point is avoided thanks to the invention. By connecting each of the coil segments with each of the strands becomes completed the interconnection of the individual coils with each other. hereby designed the production of the three-phase motor according to the invention in particular in mass production especially easy. The coils are so-called single-tooth coils with own coil core.
Der erfindungsgemäße Drehstrommotor lässt sich besonders kostengünstig aus Gleichteilen zusammensetzen, wenn die Spulensegmente jeweils gleich aufgebaut sind.Of the inventive three-phase motor can be especially inexpensive Assemble from identical parts, if the coil segments in each case the same are constructed.
Die Kontaktierung der Spulen gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn Anschlüsse der Spulen abstehen und mit einem Kontaktring verbunden sind und wenn auf dem Kontaktring die vorgesehene Verschaltung der Spulen innerhalb der Spulensegmente angeordnet ist. Durch diese Gestaltung lässt sich die Verschaltungsart einfach durch die Montage des Kontaktrings herstellen. Fehlerhafte Verschaltungen der Spulen werden hierdurch zuverlässig vermieden.The Contacting the coil designed according to another advantageous Development of the invention particularly simple when connections of the coils stand out and connected with a contact ring and if on the Contact ring the intended interconnection of the coils within the Coil segments is arranged. Through this design can be the connection method simply by mounting the contact ring produce. Faulty interconnections of the coils are thereby reliable avoided.
Zur weiteren Vereinfachung des erfindungsgemäßen Drehstrommotors trägt es bei, wenn der Kontaktring aus derselben Anzahl an Kontaktringsegmenten zusammengesetzt ist wie der Stator Spulensegmente hat. Weiterhin lässt sich hierdurch der erfindungsgemäße Drehstrommotor aus vielen kostengünstig zu fertigenden Gleichteilen zusammensetzen.to further simplification of the three-phase motor according to the invention contributes to if the contact ring consists of the same number of contact ring segments is composed of how the stator has coil segments. Farther let yourself thereby the three-phase motor according to the invention from many inexpensive put together to produce identical parts.
Die Verbindung der Kontaktringsegmente mit den einzelnen Strängen gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn jeder der Kontaktringsegmente drei Anschlusskontakte für die Stränge aufweist. Die Verbindung der Anschlusskontakte der Kontakt ringsegmente kann dann einfach durch Kontaktbrücken erfolgen.The Connection of the contact ring segments designed with the individual strands according to another advantageous embodiment of the invention particularly simple, if each of the contact ring segments has three terminal contacts for the strands. The connection of the terminal contacts of the contact ring segments can then simply by contact bridges respectively.
Die Kontaktierung der einzelnen Spulen des erfindungsgemäßen Drehstrommotors gestaltet sich besonders einfach, wenn die Anschlüsse der Spulen parallel zur Achse des Rotors angeordnet sind. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass der erfindungsgemäße Drehstrommotor hierdurch besonders kompakt aufgebaut ist.The Contacting the individual coils of the three-phase motor according to the invention makes it particularly easy when the connections of the Coils are arranged parallel to the axis of the rotor. Another Advantage of this design is that the three-phase motor according to the invention This makes it very compact.
