METHOD FOR SETTING AN OPTIMAL OPERATING POINT FOR A SYNCHRONOUS MACHINE, METHOD FOR CONTROLLING A SYNCHRONOUS MACHINE, AND SYNCHRONOUS MACHINE

摘要

The invention relates to a method for setting an optimal operating point for a synchronous machine, to a method for controlling a synchronous machine, and to a synchronous machine, wherein a functional dependency of the voltage components Ud, Uq, UE on the current components ld, lq, lE is determined for the synchronous machine by means of an FEM method or by means of a measuring method in a first method step according to the invention, and the dependency of the flex component ?d, ?q, ?? on the current components ld, lq, lE is determined therefrom according to formula (I), wherein R1 and R2 are the ohmic resistances of the corresponding windings of the synchronous machine, and the synchronous machine is operated in controlled operation in a second method step according to the invention, wherein an operating point is determined according to formulas (II), (III), and (IV) and is then set.
