Es sind Asynchronmaschinen bekannt, bei denen mittels Kommutatorhintermaschinen beliebiger Bauart in den Sekundärstromkreis zwei Spannungen eingeführt werden, von denen die eine die Sekundärspannung aufhebt, während die zweite in ihrer Größe vom Schlupf unabhängig ist und den Belastungsstrom im Sekundärstromkreis der Asynchronmaschine erzeugt. Eine derartige Anordnung hat die Eigenschaft, daß der Belastungsstrom sowohl in der Richtung als auch in der Größe vom Schlupf der Asynchronmaschine unabhängig ist. Die Anordnung kann mit Vorteil bei Umformern zur Kupplung zweier in der Periodenzahl gegeneinander schwankender Netze oder auch bei Asynchronmotoren oder Generatoren, die mit einer Kolbenarbeitsmasc'hine oder Kolbenkraftmaschine gekuppelt sind, verwendet werden.Asynchronous machines are known in which, by means of commutator rear machines of any design, two voltages can be introduced into the secondary circuit one of which cancels the secondary voltage, while the second in its magnitude of Slip is independent and the load current in the secondary circuit of the asynchronous machine generated. Such an arrangement has the property that the load current is both in direction and in magnitude is independent of the slip of the asynchronous machine. The arrangement can be advantageous in the case of converters for coupling two, the number of periods fluctuating against each other Networks or also with asynchronous motors or generators that work with a piston work machine or piston engine are coupled.
Die Erfindung betrifft eine Anordnung zur Einführung zweier Spannungen in den Sekundärstromkreis von ständergespeisten Nebenschlußkommutatormotoren, von welchen Spannungen, ähnlich wie dies für gewöhnliche Asynchronmaschinen in der geschilderten Weise bekannt ist, die eine die Spannung in der Sekundärwicklung des Kommutatormotors ganz oder teilweise aufhebt, während die zweite von der veränderlichen Frequenz im Sekundärkreis des Kommutatormotors (Schlupffrequenz) unabhängig ist, und den Arbeitsstrom in der Sekundärwicklung erzeugt. Gemäß der Erfindung ist ein mit Verstärkerwirkung arbeitender Frequenzwandler vorgesehen, der mit der einen Seite an den Kommutator des Nebenschlußmotors angeschlossen ist und mit der anderen Seite in den Sekundärstromkreis des Motors zur Einführung der die Sekundärspannung aufhebenden Gegenspannung eingeschaltet ist. Die von der Schlupffrequenz unabhängige Spannung ist dabei entweder über den Frequenzwandler oder unabhängig von diesem in den Sekundärstromkreis des Motors eingeführt. Um eine Verstärkerwirkung zu erreichen, ist der Frequenzwandler mit einer Kompensationswicklung ausgerüstet; an deren Stelle könnte er auch eine Erregerwicklung im Ständer besitzen, die vom- Kommutator gespeist wird. Wenn die von der Sc'hlupffrequenz unabhängige Spannung unabhängig von dem Frequenzwandler in den Sekundärstromkreis des Motors eingeführt ist, so kann man dies beispielsweise dadurch erreichen, daß eine zweite Kommutatorhintermaschine vorgesehen ist, deren Spannung in Reihenschaltung mit der Spannung des Frequenzwandlers in den Sekundärstromkreis des Nebenschlußmotors eingeführt ist. Wird die vom Schlupf unabhängige Spannung über den Frequenzwandler in den Sekundärkreis des Neben-The invention relates to an arrangement for introducing two voltages into the secondary circuit of stator-fed shunt commutator motors, of which voltages, similar to that for ordinary asynchronous machines is known in the manner described, the one the voltage in the secondary winding of the commutator motor completely or partially cancels, while the second of the variable frequency in the secondary circuit of the commutator motor (slip frequency) is independent, and generates the working current in the secondary winding. According to the Invention, a working with amplifier effect frequency converter is provided with one side connected to the commutator of the shunt motor and with the other side in the secondary circuit of the motor to introduce the secondary voltage canceling counter voltage is switched on. The one that is independent of the slip frequency The voltage is either via the frequency converter or independently of it in the secondary circuit of the motor introduced. In order to achieve an amplifier effect, the frequency converter is equipped with a Equipped with compensation winding; instead of this, it could also have an excitation winding own in the stator, which is fed by the commutator. If that of the push-up frequency independent voltage independent of the frequency converter in the secondary circuit of the motor is introduced, this can be achieved, for example, by having a second commutator rear machine is provided, the voltage of which is connected in series with the voltage of the frequency converter in the secondary circuit of the shunt motor is introduced. The voltage across the frequency converter is independent of the slip in the secondary circuit of the secondary
