Claims (6)

1. Läufer für einen Elektromotor mit einer Läuferwelle, auf die ein Läuferkern aufgeschoben und ein Lager, beispielsweise ein Kugellager, und ein Kom­ mutator aufgesetzt sind, und wobei Teilbereiche des Läuferkerns und der Läuferwelle zur Erzeugung einer Isolierschicht pulverbeschichtet sind, dadurch gekennzeichnet, dass die Läuferwelle (10) ein Lageranschlag-Element (11) trägt, das mittels der Isolierschicht (12) mit der Läuferwelle (10) verbunden ist.1. rotor for an electric motor with a rotor shaft, on which a rotor core is pushed and a bearing, for example a ball bearing, and a commutator are placed, and partial areas of the rotor core and the rotor shaft are powder-coated to produce an insulating layer, characterized in that the Rotor shaft ( 10 ) carries a bearing stop element ( 11 ) which is connected to the rotor shaft ( 10 ) by means of the insulating layer ( 12 ). 2. Läufer nach Anspruch 1 dadurch gekennzeichnet,
dass das Lageranschlag-Element (11) als Scheibe ausgebildet ist, die mit einem Durchbruch versehen ist, dass die Läuferwelle (10) durch diesen Durchbruch hindurchgeführt ist, und
dass die Scheibe in dem dem Läuferkern (14) zugewandten Bereich mit der Isolierschicht beaufschlagt ist und auf ihrer dem Lager zugewandten Seite eine plane Anlagefläche (11.1) bildet. 2. Runner according to claim 1, characterized in
that the bearing stop element ( 11 ) is designed as a disk which is provided with an opening, that the rotor shaft ( 10 ) is guided through this opening, and
that the disc is exposed to the insulating layer in the area facing the rotor core ( 14 ) and forms a flat contact surface ( 11.1 ) on its side facing the bearing. 3. Läufer nach Anspruch 2, dadurch gekennzeichnet, dass die dem Läuferkern (14) zugewandte Seite der als Scheibe ausge­ bildeten Lageranschlag-Elementes (11) vollständig und zusätzlich der radial außenliegende Umfangsbereich der Scheibe zumindest teilweise mit der Isolierschicht überzogen sind.3. Runner according to claim 2, characterized in that the rotor core ( 14 ) facing side formed as a disk stop element ( 11 ) completely and additionally the radially outer peripheral region of the disk are at least partially covered with the insulating layer. 4. Läufer nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass das Lageranschlag-Element (11) rotationssymmetrisch ausgebildet ist und eine zentrische Bohrung aufweist, mit der es auf die Läuferwelle (10) aufgeschoben ist.4. Rotor according to one of claims 1 to 3, characterized in that the bearing stop element ( 11 ) is rotationally symmetrical and has a central bore with which it is pushed onto the rotor shaft ( 10 ). 5. Läufer nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass das Lageranschlag-Element (11) aus einem Material besteht, dessen Schmelzpunkt oberhalb der Plastifiziertemperatur der Pulverbeschichtung liegt.5. Runner according to one of claims 1 to 4, characterized in that the bearing stop element ( 11 ) consists of a material whose melting point is above the plasticizing temperature of the powder coating. 6. Läufer nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass die Isolierschicht aus einem Duromer, insbesondere aus Epoxidharz besteht.6. Runner according to one of claims 1 to 5, characterized, that the insulating layer made of a thermoset, in particular of epoxy resin consists.
