  • Method for operating an electrical machine
    Patent number: 9337765
    Abstract: 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. The method includes simultaneously recording vibration measurements by means of which the elliptic vibration modes of the two coil ends 2 can be determined as a factor of time; determining the ellipse inclinations and the phase positions of elliptic vibration modes of the two coil ends 2; determining critical operating states of the electrical machine, in which the elliptic inclinations and the phase positions of the elliptic vibration modes of the two coil ends are substantially identical; and operating the electrical machine in such a manner that the critical operating states can be avoided by varying the idle power of the electrical machine.
