Description

Schaltanordnung zur gleichmäßigen Lastverteilung auf mechanisch gekuppelte Asynchronmotoren Um mechanisch gekuppelte und an das gleiche Netz angeschlossene Asynchronmotoren gleichmäßig zu belasten, werden ihre Läuferwicklungen nach Patent 478 o4I so ausgeführt, daß ihre Achsen den gleichen oder nahezu gleichen Winkel miteinander einschließen wie die Ständerwicklungsachsen und zusammengehörige Phasen so hintereinandergeschaltet sind, daß die elektromotorischen Kräfte in den zusammengehörigen Phasenwicklungen der Läufer gleich oder nahezu gleich sind. Zum Zwecke der Drehzahlregelung oder Phasenkompensation können bei dieser Anordnung auch Kommutatorwicklungen von Drehstromkollektormaschinen oder Frequenzwandlern mit den Läuferwicklungen der Asynchronmotoren in Reihe geschaltet werden.Switching arrangement for even load distribution on mechanically coupled Asynchronous motors To mechanically coupled and connected to the same network To load asynchronous motors evenly, their rotor windings are patented 478 o4I designed so that their axes have the same or almost the same angle include with each other like the stator winding axes and associated phases are connected in series so that the electromotive forces in the associated Phase windings of the rotors are the same or almost the same. For the purpose of speed control or phase compensation can also use commutator windings in this arrangement Three-phase collector machines or frequency converters with the rotor windings of the asynchronous motors can be connected in series.

Erfindungsgemäß erfolgt die Drehzahlregelung besonders vorteilhaft statt durch Drehstromkollektormaschinen oder Frequenzwandler durch eine aus Umformer und Gleichstromhintermotor bestehende Anordnung (vgl. Patent I77 27o), bei der die Erregung des Gleichstrommotors selbsttätig oder von Hand geregelt wird. Der Gleichstrommotor kann statt mit den Hauptmotoren auch in bekannter Weise mit einem an irgendeinem Netz liegenden Generator gekuppelt sein.According to the invention, the speed control is particularly advantageous instead of three-phase collector machines or frequency converters by a converter and DC rear motor existing arrangement (see. Patent I77 27o), in which the Excitation of the DC motor is regulated automatically or by hand. The DC motor instead of the main engines, it can also be used in the known manner with one on any one The generator must be connected to the mains.
