Abstract

Die Erfindung bezieht sich auf die Anordnung eines Stators und eines Reservestators. Zur Vermeidung ständiger Korrektur bei der Länge der Antriebswelle (16) wird der Reservestator mit dem gerade betriebenen Stator (38) verbunden bzw. einstückig ausgeführt. Bei entsprechendem Verschleiß wird diese Statorkombination lediglich um 180° zur Längsachse umgekehrt bzw. ein Zwischenrohr (40) eingesetzt, so daß der Reservestator in den Rotorbereich (42,44) zum Eingriff gelangt.
