Abstract

Die Erfindung betrifft einen Stator, einen Distanzpack für einen Statorkern und einen Generator. Ein Distanzpack (134) zur Reduzierung von Vibrationen eines Statorkerns ist offenbart. Der Statorkern kann eine Mehrzahl von Blechen (132) enthalten, die mit einem Schwalbenschwanz eines Keilstabes (126) verbunden sind und durch einen Distanzblock (136, 139) getrennt sind. Der Distanzpack (134) kann einen länglichen Körper (152) enthalten, der sich von einem ersten Ende (154) enthaltend einen Schwalbenschwanzschlitz zur Verbindung mit dem Schwalbenschwanz des Keilstabs (126) bis zu einem zweiten Ende (158) erstreckt, sich radial erstreckend zumindest im Wesentlichen entlang einer gesamten Länge eines benachbarten Distanzblocks (136, 139). Ein Stator und ein betreffender Generator, enthaltend den Distanzpack (134), können auch bereitgestellt werden.
