Description
Schaltung zur elektrodynamischemixez isiing einer dreiphasig gewickelten, aber bei Motorbetrieb einphäsi,,espeisten Induktionsmaschine Es sind Schaltungen für Asynchronmaschinen vorgeschlagen worden, bei denen die induzierende Wicklung- einphasig an das Netz angeschlossen ist und wenigstens zwei magnetische Achsen hat, längs deren vermöge besonderer Maßnahmen die Ströme zeitlich gegeneinander in der Phase verschoben sind.Circuit for electrodynamic mixing isiing a three-phase wound, but when the motor is running, induction machines are fed in. They are circuits has been proposed for asynchronous machines in which the inducing winding is single-phase connected to the grid and has at least two magnetic axes, along the lines of which, by virtue of special measures, the currents against each other in time Phase are shifted.
Weiter ist eine- Gleichlaufschaltung für nach Art von Induktionsmaschinen gebaute Aggregate bekanntgeworden, bei der für die Ruhelage einphasiger Netzanschluß der primären Teile vorgesehen ist und die auf Widerstände geschalteten Läufer infolge des Kurzschlusses zweier Phasen des primären Teiles nicht weiterlaufen können.Next is a synchronization circuit for on the type of induction machines built aggregates become known, with the single-phase mains connection for the rest position of the primary parts is provided and the rotor connected to resistors as a result the short circuit of two phases of the primary part cannot continue.
Nach der Erfindung kann eine vorteilhafte Bremsschaltung für eine Induktionsmaschine mit mehrachsiger Wicklung und einphasigem Netzanschluß des primären Teiles dadurch erreicht werden, daß die Primärwicklung nach Art eines synchronisierten Asynchronmotors geschaltet wird, bei dem zwei parallel geschaltete Phasen in Serie zur dritten Phase liegen. Der induzierende Stromkreis wird an den Enden der beiden parallelen Phasen und an der dritten Phase an das Netz einphasig angeschlossen. Beim Übergang vom Motorzum Bremsbetrieb wird ein in der Verbindungsleitung der beiden parallel geschalteten Phasen liegender, gegebenenfalls regelbarer induktiver oder kapazitiver Widerstand durch einen Schalter überbrückt.According to the invention, an advantageous braking circuit for a Induction machine with multi-axis winding and single-phase mains connection of the primary Part can be achieved in that the primary winding in the manner of a synchronized Asynchronous motor is switched, in which two phases connected in parallel in series to the third phase. The inducing circuit is at the ends of the two parallel phases and single-phase connected to the third phase to the network. During the transition from motor to braking operation, there is a in the connecting line between the two Phases connected in parallel and optionally adjustable inductive or capacitive resistance bridged by a switch.
Eine Anordnung, bei der eine derartige Umschaltung möglich ist, kennzeichnet Fig. i. Es bedeutet hier i das Netz, 2 und 3 die parallel geschalteten Phasen des induzierenden Teiles, 4 die dritte hierzu in Serie geschaltete Phase, 5 eine regelbare Drosselspule, die im Stromkreis der Phase 2 liegt. Der Rotor der Maschine ist nicht eingezeichnet. Die Drosselspule kann durch den Schalter 6 überbrückt werden. Ist der Schalter 6 geschlossen, so wird eine Schaltung nach Fig.3 hergestellt. Die Charakteristik verläuft generatorisch (Kurve a in Fig..2). Wird Schalter 6 geöffnet, so verläuft die Charakteristik motorisch (Kurve b in Fig. 2). Man hat es nach dieser Schaltung in der Hand, lediglich mit Hilfe des Überbrückungsschalters 6 die Charaktehstik des Motors in eine motorische bzw. in eine generatorische zu verwandeln und daher den Motor lediglich mit Hilfe dieses Schalters nach Bedarf entweder zum Heben oder Senken zu benutzen. Ein weiterer Vorteil dieser Schaltung liegt ferner darin, daß man den Motor nach Fig. i oder Fig. 3 nach Bedarf auch als normalen Drehstromasynchronmotor mit dreiphasigem Anschluß an das- Netz verwenden kann.An arrangement in which such a switchover is possible denotes Fig. I. Here i means the network, 2 and 3 the phases of the connected in parallel inducing part, 4 the third phase connected in series for this purpose, 5 a controllable one Choke coil that is in the phase 2 circuit. The rotor of the machine is not drawn. The choke coil can be bridged by switch 6. is if the switch 6 is closed, a circuit according to FIG. 3 is produced. The characteristic runs as a generator (curve a in Fig. 2). If switch 6 is opened, it runs the motor characteristic (curve b in Fig. 2). You have it after this circuit in the hand, only with the help of the bypass switch 6 the character aesthetics of the motor in a motor or in a generator and therefore just use this switch to either lift or lift the motor as required To use sinks. Another advantage of this circuit is that the motor according to FIG. 1 or FIG. 3 can also be used as a normal three-phase asynchronous motor as required with three-phase connection to the network.
