Description
Ein- oder Mehrphasen-Induktionsmotor mit Kurzschlußanker, bei dem als Stirnverbindungen für die Ankerleiter die eisernen Deckplatten des Ankerkörpers dienen. Um unter Erzielung eines relativ hohen Anzugdrehmomentes den Anlaufstrom von Ein- oder Mehrphasen-Induktionsmotoren, bei denen als Stirnverbindungen für die Ankerleiter die eisernen Deckplatten dienen, herabzusetzen, soll erfindungsgemäß der Widerstand dieser Deckplatten durch radiale Einschnitte erhöht werden.Single or multi-phase induction motor with short-circuit armature, in which the iron cover plates of the anchor body as end connections for the anchor ladder to serve. To reduce the starting current while achieving a relatively high tightening torque of single or multi-phase induction motors, where as end connections for the anchor ladder serve to lower the iron cover plates, according to the invention the resistance of these cover plates can be increased by radial incisions.
In der Figur ist der Anker des Induktionsmotors in perspektivischer Ansicht dargestellt. Es bedeutet: A das Ankereisen, W die Welle, D die eiserne Deckplatte mit den Einschnitten S, L die Ankerleiter. Die Wirkung dieser Einrichtung ist folgende.In the figure, the armature of the induction motor is shown in a perspective view. It means: A the anchor iron, W the shaft, D the iron cover plate with the incisions S, L the anchor ladder. The effect of this facility is as follows.
Infolge des Skineffektes in den eisernen Stirnverbindungen ist beim Anlauf der Widerstand des Rotorstromkreises relativ hoch, da beim Anlauf im Rotorstromkreis Ströme von derNetzfrequenz fließen. Der hoheWiderstand bedingt eine Herabsetzung des Anlauf-Stromes unter gleichzeitiger Entwicklung eines hohen Anzugdrehmomentes. Beim Anlauf des Motors sinkt die Frequenz der Rotorströme auf den der Schlüpfung entsprechenden Wert, so daß also der Widerstand des Rotorstromkreises ein kleinerer ist. Eine erhöhte Wirkung bringt nun die Anordnung der radialen Schlitze in den Deckplatten, da sie die Stromwege in den Stirnverbindungen verlängern und den Verlauf eindeutig festlegen.As a result of the skin effect in the iron forehead connections, the Starting the resistance of the rotor circuit is relatively high, since it is in the rotor circuit when starting Currents from the mains frequency flow. The high resistance causes a reduction of the starting current with simultaneous development of a high tightening torque. When the motor starts up, the frequency of the rotor currents drops to that of the slip corresponding value, so that the resistance of the rotor circuit is a smaller one is. The arrangement of the radial slots in the has an increased effect Cover plates, as they extend the current paths in the end connections and the course clearly set.
