ELECTRIC MACHINE, METHOD FOR OPERATING A SEPARATELY EXCITED SYNCHRONOUS MACHINE AND USE OF A SEPARATELY EXCITED SYNCHRONOUS MACHINE

摘要

The invention relates to a method for operating a separately excited synchronous machine, to an electric machine and to the use thereof, wherein field coils are arranged at the rotor of the synchronous machine, wherein the synchronous machine is operated as a reluctance machine or as an asynchronous machine in case of non-energization of the field coils, in particular in case of emergency operation and/or excitation field failure.
