Contents

A new method of calculation of zero-sequence currents and electromagnetic torque of a three-phase slip-ring induction machine is presented in the paper. The zero-sequence equivalent circuit of an induction machine has the single-phase winding in the stator and the single-phase winding in the rotor. In such system generation of infinite sequence of stator's and rotor's currents with various frequencies takes place. Examples of calculations of zero-sequence currents and torque are presented.

Übersicht

In dem Artikel wird ein mathematisches Modell vom Nullsystem der Dreiphasen-Schleifringläufermaschine bearbeitet. Das Modell vom Nullsystem enthält die einphasige Wicklung im Ständer und die einphasige Wicklung im Läufer. In der Arbeit wird eine Methode zur Berechnung der Ströme und Drehmomente vorgelegt. Es wird gezeigt, daß unendliche Reihen für die Ströme im Ständer und Läufer entstehen. Es werden beispiele von der Strom- und Drehmomentberechnung des Nullsystems dargestellt.
