Wolf-Dieter Dr. Dipl.-Ing. Weigel,Dieter Dipl.-Ing. Köllensperger,Theodor Dipl.-Ing. Salzmann,Thomas Schlegel,Weigel Wolf-Dieter Dr-Ing +4 more
TL;DR: In this article, a drive for a rotating field machine which has two AC voltage integrators of identical design for forming two electric voltage signals each of which is proportional to a flux component in the machine is described.
Patent
Circuit for generating an electric signal proportional to a flux component of a rotating-field machine
Wolf-Dieter Dr. Dipl.-Ing. Weigel,Dieter Dipl.-Ing. Köllensperger,Theodor Dipl.-Ing. Salzmann,Thomas Schlegel,Weigel Wolf-Dieter Dr-Ing +4 more
TL;DR: In this article, an AC voltage integrator was used to determine the position of the flux of a rotating field machine, with the correct phase and amplitude, and independently of frequency, while the zero-controller remains engaged at speeds from the beginning of localization of standing rotor position up to the nominal frequency of the machine.
Patent
Circuit for forming a voltage signal which is proportional to a magnetic flux component within a rotating field machine
Walter Dipl Ing Dreiseitl,Dieter Dipl.-Ing. Köllensperger,Theodor Dipl.-Ing. Salzmann,Thomas Schlegel,Wolf-Dieter Dr. Dipl.-Ing. Weigel +4 more
TL;DR: In this paper, the authors describe an electrical voltage signal which is a flux component (ψ R) in a rotating field machine (M) proportional to the frequency (ω) of the rotary field machine(M) weighted (a; F1) the input of the proportional controller (V3) to the input to the maximum frequency (V4) this paper.
