EMI1.1
EMI1.2
Es ist schon vorgeschlagen worden, den zweiphasigen Läufer einer Induktionsmaschine mit zwei Einphasenkollektormaschinen (zweckmässig Maschinen mit kompensierter Ankerrückwirkung) in Kaskade zu schalten. Es ist auch bekannt, die Erregung jeder Kollektormaschine durch ihren eigenen Ankerstrom zu bewirken oder den Erregerstrom im Nebenschluss an den Klemmen der zweiten Maschine abzunehmen.
Gemäss vorliegender Erfindung wird zwar die Erregung jeder Einphasenmaschine ebenfalls im Nebenschluss an den Klemmen der zweiten Maschine abgenommen, jedoch unter Zwischenschaltung des Sekundärkreises eines Transformators, dessen primärer Stromkreis vom Anker-

von Kollektormaschinen mittels Serien-Tramformatoren bekannt ist.
In der Zeichnung ist die Schaltung nach vorliegender Erfindung an einem Ausfiihrungsbeispiel veranschaulicht.
Die Schleifringmaschine, deren Rotor und Stator mit R bzw. mit 8 bezeichnet sind, ist

maschine A, Al geschaltet, die mit Erregerwicklungen C, Cl und Kompensationswicklungen B, Z versehen sind. Die Erregerwicklung jeder Kollektormaschine liegt im Nebenschluss zur anderen Maschine, und zwar unter Zwischenschaltung der Sekundärwicklung von Serientransformatoren D und D Die Primärwicklungen der Transformatoren sind mit den Bürsten der Schleifringe 1, 2 verbunden und werden von dem Strom der der Erregerwicklung nicht zugehörigen Kollektormaschine durchflossen.
Diese Schaltung bietet die Möglichkeit, eine beliebige Nebenschluss-oder KompoundCharakteristik zu erzielen, ohne, wie dies bisher notwendig war, die Anordnung eines Phasenumformers zu erfordern, da die beiden Einphasenkollektormaschmen aufeinander als Phasenumformer wirken.
An dem Wesen der Erfindung wird selbstverständlich njchts geändert, wenn die Erregung jeder Einphasenmaschine teilweise im Nebenschluss an den Klemmen der anderen masche'' und teilweise an ihren eigenen Klemmen erfolgt.

EMI1.1
EMI1.2
It has already been proposed to cascade the two-phase rotor of an induction machine with two single-phase collector machines (expediently machines with compensated armature feedback). It is also known to cause each collector machine to be excited by its own armature current or to shunt the excitation current from the terminals of the second machine.
According to the present invention, the excitation of each single-phase machine is also taken off in the shunt at the terminals of the second machine, but with the interposition of the secondary circuit of a transformer, whose primary circuit is from the armature
EMI1.3
of collector machines by means of serial Tramformatoren is known.
In the drawing, the circuit according to the present invention is illustrated using an exemplary embodiment.
The slip ring machine, the rotor and stator of which are denoted by R and 8, respectively
EMI1.4
machine A, Al switched, which are provided with excitation windings C, Cl and compensation windings B, Z. The excitation winding of each collector machine is shunted to the other machine, with the interposition of the secondary winding of series transformers D and D. The primary windings of the transformers are connected to the brushes of slip rings 1, 2 and the current of the collector machine not belonging to the excitation winding flows through them.
This circuit offers the possibility of achieving any desired shunt or compound characteristic without requiring the arrangement of a phase converter, as was previously necessary, since the two single-phase collector systems act on one another as phase converters.
The essence of the invention is of course not changed if the excitation of each single-phase machine takes place partly in shunt on the terminals of the other "mesh" and partly on its own terminals.
