Abstract
(DE)
Ein Verfahren zum Betreiben einer elektrischen Maschine aufweisend einen Stator 1 mit einer Wicklung aus elektrischen Leitern, welche zwei gegenüberliegende Wickelköpfe 2 aufweist, weist folgende Schritte auf: Zeitgleiches Erfassen von Schwingungsmessgrößen mit denen die Ellipsierungsschwingungsmoden der beiden Wickelköpfe 2 bestimmbar sind in Abhängigkeit von der Zeit; Bestimmen der Ellipsenneigungen und der Phasenlagen der Ellipsierungsschwingungsmoden der beiden Wickelköpfe 2; Ermitteln von kritischen Betriebszuständen der elektrischen Maschine, bei denen die Ellipsenneigungen und die Phasenlagen der Ellipsierungsschwingungsmoden der beiden Wickelköpfe im Wesentlichen gleich sind; Betreiben der elektrischen Maschine derart, dass die kritischen Betriebszustände mittels einer Variation der Blindleistung der elektrischen Maschine vermieden werden.
(EN)
A method for operating an electrical machine, having a stator 1 with a coil from electrical conductors, which has two coil ends 2 lying opposite each other, has the following steps: simultaneous recording of vibration measurands by means of which the elipsing vibration modes of the two coil ends 2 can be determined as a factor of time; determining the elipsing inclinations and the phase positions of the elipsing vibration modes of the two coil ends 2; determining critical operating states of the electrical machine, on which the elipsing inclinations and the phase positions of the elipsing vibration modes of the two coil ends are substantially identical; operating the electrical machine in such a manner that the critical operating states can be avoided by means of varying the idle power of the electrical machine.
