KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch das Haupt patent ist es bekannt geworden , Mehrphasenkollektormaschinen dadurch zu regeln, daß man parallel zum Ständer und Läufer Widerstände schaltet. Fig. 1 gibt diese Anordnung mit den im Hauptpatent gewählten Bezeichnungen wieder.The main patent made it known, multi-phase collector machines thereby to regulate that one switches resistors parallel to the stator and rotor. Fig. 1 reproduces this arrangement with the designations chosen in the main patent.
Diese Schaltung weist jedoch bei Untersynchronismus einen ziemlich schlechten Leistungsfaktor auf, weil da nur ein Teil der to Ständerwicklung α vom Magnetisierungsstrom durchflossen, also nicht die ganze Ständerwicklung als Feldwicklung benutzt wird.However, this circuit has a rather poor power factor in the case of subsynchronism, because magnetizing current flows through only part of the stator winding α, i.e. not the entire stator winding is used as a field winding.
Dieser Nachteil wird nach der Erfindung ganz oder teilweise dadurch aufgehoben, daß Anfang und Ende der Widerstände bzw. Drosselspulen nicht an einander entsprechende Punkte zweier Ständerphasen angeschlossen werden, sondern an Punkte verschiedenen Potentials der Größe nach, wodurch das Ständerfeld im günstigsten Sinne verdreht und somit ein besserer Leistungsfaktor erzielt werden kann.This disadvantage is completely or partially eliminated according to the invention in that The beginning and end of the resistors or inductors do not correspond to one another Points of two stator phases are connected, but at points different Potential according to size, whereby the stator field is twisted in the most favorable sense and thus a better power factor can be achieved.
In der schematischen Darstellung der Fig. 2 bedeuten g die Ständerwicklungen und α und b die bezüglichen Anschlußpunkte verschiedenen Potentials für die Widerstände d. In the schematic representation of FIG. 2, g denotes the stator windings and α and b denote the connection points of different potentials for the resistors d.
Der Symmetrie halber sollen sämtliche Anfänge α und Enden b der Widerstände bzw. Drosselspulen je das gleiche Potential der Größe nach haben.For the sake of symmetry, all beginnings α and ends b of the resistors or inductors should each have the same potential in terms of size.
