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 U_d, U_q, U_E on the current components l_d, l_q, l_E 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 Ψ_d, Ψ_q, Ψ_Ε on the current components l_d, l_q, l_E 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.
