KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Anker der Induktionsmotoren bestehen bekanntlich aus einem lameliierten Eisenkörper, der bei kleineren Motoren meist unmittelbar, bei größeren dagegen vermittels einer besonderen Nabenkonstruktion auf die Motorwelle aufgesetzt und seitlich durch sogen. Preßflantschen zusammengehalten wird. Diese werden gewöhnlich vermittels durch den Eisenkörper hindurchgehender Schrauben oder eines auf der Welle aufgeschnittenen Gewindes und Muttern zusammengehalten. Die Wickelung ist entweder in sich selbst oder vermittels fester oder veränderlicher (regelbarer) Widerstände geschlossen.As is well known, the armatures of induction motors consist of a laminated iron body, in the case of smaller engines usually directly, in the case of larger engines, however, by means of a special one Hub construction placed on the motor shaft and laterally by sucked. Press flanges is held together. These are usually by means of screws going through the iron body or one on the shaft cut thread and nuts held together. The winding is either in itself or by means of fixed or variable (controllable) resistances closed.
Der Anker gemäß vorliegender Erfindung besitzt einen Aufbau, welcher sowohl den Zweck der Stabwickelung als denjenigen der Preßschrauben in sich vereinigt und außerdem dem induzierten Strome einen veränderlichen Widerstand bietet (Fig. 1 bis 3).The anchor according to the present invention has a structure which both the Purpose of the rod winding as that of the press screws combined and also offers a variable resistance to the induced currents (Figs. 1 to 3).
Der lameliierte Eisenkörper α wird seitlich durch elektrisch gut leitende Preßflantschen b begrenzt, welche in eigenartiger Weise durch die nahe am Umfang in gestanzten Löchern des Eisenkörpers eingebetteten Stäbe c der Wickelung in axialer Richtung zusammengehalten werden. Da, wo die Stäbe aus dem Eisenkörper beiderseits heraustreten, sind sie radial nach der Mitte zu abgebogen und greifen mit ihren Enden in die Lücken eines am Umfange der Preßflantschen b angegossenen Zahnkranzes d. The laminated iron body α is laterally bounded by electrically highly conductive pressure flanges b , which are held together in the axial direction in a peculiar manner by the rods c of the winding, which are embedded close to the circumference in punched holes in the iron body. Where the rods protrude from the iron body on both sides, they are bent radially towards the center and their ends grip into the gaps of a ring gear d cast on the circumference of the press flanges b.
Nach dem Einlegen und Umbiegen der Kupfer- oder Messingstäbe c werden die Zähne des Kranzes d unter einer Presse in der in der Zeichnung angedeuteten Weise umgebogen, so daß sie die Stabenden klauenartig umfassen und mit diesen eine kompakte Masse bilden.After inserting and bending the copper or brass rods c , the teeth of the ring d are bent under a press in the manner indicated in the drawing, so that they encompass the rod ends like claws and form a compact mass with them.
Diese Verbindung bietet, weil nur durch Pressung erzeugt, in kaltem Zustande, d. h. beim Anlauf des Motors einen gewissen Widerstand, welcher, sobald der Anker infolge der Belastung des Motors warm geworden ist, infolge der durch die Wärme hervorgerufenen Ausdehnung von selbst geringer wird, weil dadurch an den Kontaktstellen der Stäbe mit den klauenartigen Zähnen eine starke Pressung entsteht. Der Widerstand der Stabwickelung wird um so kleiner, je größer die Belastung des Motors, d. h. je wärmer der letztere wird.This connection, because it is produced only by compression, offers in the cold state, i.e. H. when starting the motor a certain resistance, which, as soon as the armature as a result of the Load on the engine has become warm as a result of the heat generated Expansion is less by itself, because it is at the contact points of the rods with the claw-like teeth create a strong pressure. The resistance of the rod winding becomes the smaller, the greater the load on the engine, d. H. the warmer the latter gets.
