Abstract
Description
Die Erfindung betrifft einen Elektromotor, insbesondere zum Antrieb einer hydraulischen Pumpe für eine schlupfgeregelte Kraftfahrzeugbremsanlage nach dem Oberbegriff des Patentanspruchs 1. The invention relates to an electric motor, in particular for Drive a hydraulic pump for a slip-controlled Motor vehicle brake system according to the preamble of Claim 1.
Aus der WO 00/28639 ist bereits ein Verfahren zur Herstellung eines Rotors oder Stators für einen Elektromotor bekannt, bei dem einzelne Lamellen des Stators oder Rotors aus mehreren miteinander verbundenen Segmenten bestehen. Die verbundenen Segmente werden aus streifenförmigen Blechwerkstoff ausgetrennt, zur Bildung eines Lamellenpaketes deCkungsgleich gestapelt und in einem späteren Arbeitsgang zur Zylinderform gerollt. Die anschließende Fügung der Segmente findet hierbei im Statorjoch, das heißt zwischen Statorzähnen, statt. WO 00/28639 already describes a method for Manufacture of a rotor or stator for an electric motor known in which individual slats of the stator or rotor several interconnected segments exist. The connected segments are made of strip-shaped Separated sheet metal material to form a laminated core stacked in the same way and used in a later operation Rolled cylindrical shape. The subsequent joining of the segments takes place in the Statorjoch, that is between Stator teeth instead.
Ein Nachteil dieser Vorgehensweise ist darin zu sehen, daß aufgrund der großen Lücken zwischen den über dünne Stege miteinander verbundenen Segmenten keine wirtschaftliche Werkstoffausnutzung des Blechwerkstoffes stattfindet. Ein weiterer Nachteil ist darin zu sehen, daß ein Biegeprozeß der verbundenen Segmente notwendig ist. Dies bedeutet einen zusätzlichen Arbeitsaufwand und die Baugröße steigt aufgrund der nach dem Biegen abstehenden Stege. A disadvantage of this approach is that due to the large gaps between the over thin webs interconnected segments no economic Material utilization of the sheet metal material takes place. On Another disadvantage is the fact that a bending process of the connected segments is necessary. This means one additional workload and the size increases due to the webs protruding after bending.
Es ist weiterhin bekannt, ringförmig geschlossene Lamellen aus streifenförmigem Blechwerkstoff auszutrennen, wobei zur Bildung einer mittigen Ausnehmung sowie von beabstandeten, in Richtung Lamellenzentrum weisenden Zähnen ein Trennvorgang erforderlich ist. Der Werkstoff dieser Ausnehmung ist verloren und kann nur der Wiederverwertung zugeführt werden. It is also known to have annularly closed lamellae to separate from strip-shaped sheet metal material, whereby for Formation of a central recess and of spaced teeth pointing towards the lamella center Separation process is required. The material of this recess is lost and can only be recycled.
Daher ist es die Aufgabe der vorliegenden Erfindung, einen Elektromotor der eingangs genannten Art mit möglichst einfachen, kostengünstigen und funktionssicheren Mitteln zu verbessern, um die genannten Nachteile zu beseitigen. It is therefore the object of the present invention to provide a Electric motor of the type mentioned with possible simple, inexpensive and reliable means improve to eliminate the disadvantages mentioned.
Diese Aufgabe wird erfindungsgemäß für einen Motor der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. This object is the invention for an engine initially mentioned type with the characteristic features of the Claim 1 solved.
Weitere Merkmale, Vorteile und zweckmäßige Ausgestaltungsvarianten der Erfindung gehen aus Unteransprüchen hervor. Die Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Other features, advantages and practical Embodiment variants of the invention emerge from subclaims. The invention is described in more detail below with the aid of a drawing explained.
Es zeigen: Show it:
Fig. 1a, 2a den prinzipiellen Aufbau einer Lamelle aus mehreren Segmenten FIG. 1a, 2a, the basic structure of a lamella from a plurality of segments
Fig. 1b, 2b zwei Ausführungsformen zur Anordnung der Segmente auf einem streifenförmigen Blechwerkstoff. FIG. 1b, 2b show two embodiments for the arrangement of the segments on a strip-shaped sheet-metal material.
Die Fig. 1a zeigt eine Lamelle 1 eines Stators oder Rotors für einen Elektromotor, der insbesondere zum Antrieb einer hydraulischen Pumpe für Kraftfahrzeugbremsanlagen geeignet ist. Eine Verwendung für andere Zwecke wie beispielsweise eine elektromechanische Bremse ist möglich. Die Lamelle 1besteht aus mehreren, idealerweise identischen, Segmenten 2, 3, 4, deren Trennstellen 5, 6, 7 sich in den Statorzähnen 8, 9, 10 befinden, wobei sich zwischen den getrennten Statorzähnen 8, 9, 10 noch weitere ungetrennte Statorzähne befinden können. Hierdurch wird zum einen eine vereinfachte Montage aufgrund der großen Anlageflächen der Trennstellen 5, 6, 7 erreicht, zum anderen ist die Lage der Trennstellen 5, 6, 7 in den Statorzähnen 8, 9, 10 magnetisch günstig, da hier die magnetische Flußrichtung parallel zu den Luftspalten, entstanden durch die Trennstellen 5, 6, 7, verläuft. Somit wirken sich die Trennstellen 5, 6, 7 nicht negativ auf den Magnetkreis aus. The Fig. 1a shows a blade 1 of a stator or rotor for an electric motor, which is particularly suitable for driving a hydraulic pump for motor vehicle brake systems. Use for other purposes, such as an electromechanical brake, is possible. The lamella 1 consists of several, ideally identical, segments 2 , 3 , 4 , the separation points 5 , 6 , 7 of which are located in the stator teeth 8 , 9 , 10 , wherein there are still further undivided stator teeth between the separated stator teeth 8 , 9 , 10 can be located. In this way, on the one hand, a simplified assembly is achieved due to the large contact surfaces of the separating points 5 , 6 , 7 , on the other hand, the position of the separating points 5 , 6 , 7 in the stator teeth 8 , 9 , 10 is magnetically favorable, since here the magnetic flow direction is parallel to the air gaps, created by the separation points 5 , 6 , 7 , runs. The separation points 5 , 6 , 7 thus do not have a negative effect on the magnetic circuit.
Die Fig. 1b zeigt eine bevorzugte Anordnung der einzelnen Segmente 2, 3, 4 auf einem Blechwerkstoff 11. Die Segmente 2, 3, 4 werden hierbei mit einer hohen Materialausnutzung und gleichsinniger Walzrichtung (A) der einzelnen Segmente 2, 3, 4 aus dem Blechwerkstoff 11 herausgetrennt, insbesondere gestanzt. Bei einer aus den Segmenten 2, 3, 4 zusammengesetzten Lamelle 1 verläuft die Walzrichtung (A) jeweils annähernd radial in Richtung auf den Mittelpunkt der zusammengesetzten Lamelle 1 zu, bzw. weg. FIG. 1b shows a preferred arrangement of the individual segments 2, 3, 4 on a sheet material. 11 The segments 2 , 3 , 4 are cut out of the sheet material 11 , in particular punched, with a high material utilization and the same direction of rolling (A) of the individual segments 2 , 3 , 4 . In the case of a lamella 1 composed of the segments 2 , 3 , 4 , the rolling direction (A) runs approximately radially towards or away from the center of the assembled lamella 1 .
Die Fig. 2a ist äquivalent zur Fig. 1a aufgebaut. Fig. 2a is constructed equivalent to Fig. 1a.
Fig. 2b zeigt eine andere bevorzugte Anordnung der einzelnen Segmente 2', 3', 4' auf einem Blechwerkstoff 11'. Die Segmente 2', 3', 4' werden hierbei wiederum mit einer hohen Materialausnutzung und gleichsinniger Walzrichtung (B) der einzelnen Segmente 2', 3', 4' aus dem Blechwerkstoff 11' herausgetrennt, insbesondere gestanzt. Bei einer aus den Segmenten 2', 3', 4' zusammengesetzten Lamelle 1' verläuft die Walzrichtung (B) jeweils annähernd in Umfangsrichtung der Lamelle 1'. FIG. 2b shows another preferred arrangement of the individual segments 2 ', 3', 4 'on a sheet material 11'. The segments 2 ', 3 ', 4 'are again cut out, in particular punched, from the sheet metal material 11 ' with high material utilization and the same direction of rolling (B) of the individual segments 2 ', 3 ', 4 '. In the case of a lamella 1 'composed of the segments 2 ', 3 ', 4 ', the rolling direction (B) runs approximately in the circumferential direction of the lamella 1 '.
Der Einfluß von Materialanisotropien (unterschiedliche Werkstoffeigenschaften in Walzrichtung und quer dazu) wird verringert. Prinzipiell werden möglichst wenige Segmente zusammengefügt, um die Entstehung von zusätzlichen Luftspalten im Magnetkreis zu vermeiden. The influence of material anisotropies (different Material properties in the rolling direction and across) reduced. In principle, as few segments as possible put together to create additional air gaps in the Avoid magnetic circuit.
