   gesamte Stromstoss   wird also stets zur Beschleunigung oder Verzögerung des Propellers ausgenutzt, so dass diese ausserordentlich sehnen auf hohe oder geringe Geschwindigkeit gebracht werden kann. 



  Die Dauer des auftretenden Stromstosses wirdhiedutch so erheblich   beschränkt, dass   die Wicklungen des Motors nicht übermässig auf Erwärmung beansprucht werden. Auch die Kommutierung des starken Stromstosses findet funkenfrei statt, da die Ankergeschwindigkeit bei seinem Auftreten nur gering ist und ausserdem die Erwärmung der Kohlen bis zum Funken immerhin eine gewisse Zeit beansprucht. 



   Um von der grossen Zeitkonstante des Erregerstromkreises und dem dadurch bedingten langsamen Ansteigen des Feldes unabhängig zu sein, wird man die Erregung der Motoren dauernd an Spannung liegen lassen, so dass bereits im Momente des Einschaltens des   Ankerstromco volle   Feldstärke herrscht. 



   Wegen der stets vorhandenen Selbstinduktion des Ankerstromkreises setzt der Strem im Einschaltmomente mit dem Werte Null ein, er gelangt erst nach Ablauf einer allerdings sehr kurzen Zeit auf seinen Maximalwert. um dann wegen der schnell zunehmenden Geschwindigkeit des Motors wieder zu fallen und schliesslich auf seinen normalen Wert zu gelangen. Es kann vorkommen. dass die Selbstinduktion des Ankers bei grossen Maschinen so gering ist, dass der maximale   Stromstoss   übermässig gross wird und Schädigungen am Motor und an der   speisenden Akkumu-     latorenbatterie im Gefolge   hat. Um derartige Störungen zu vermeiden. soll   im Ankerstromkreis   eine Selbstinduktionsspule vorgeschaltet werden, die die Schnelligkeit des Strommanstieges und das Maximum des Stromes beliebig zu begrenzen gestattet. 



   Sehr vorteilhaft ist es, wenn man die Selbstinduktion in die Maschine selbst verlegt, indem man die Feldmagnete mit einer vom Ankerstrom durchflossenen   Kompoundierungswickiung   versieht. Es tritt dann nicht nur die reine Selbstinduktionswirkung auf, sondern der Stromstoss wird auch dadurch geschwächt, dass durch das starke Feld auch bei   kleiner Geschtndigko !   des Motors bereits grössere gegenelektromotorische Kräfte induziert werden. Besonders zweckmässig ist es, die   Kompoundierungswicklung   nicht unmittelbar 111 Reihe mit   dem Ankerstrom   zu schalten, sondern sie durch einen Transformator   induktiv mit dem Ankerkrose zu kuppen.   



  Man erreicht dadurch die Wirkung, dass nur der starke Anstieg des Stromes   tüi   Anfang der Beschleunigungsperiode auf das Feld des Motors und damit auf die   Gfgen-EMK wirkt. dass dagegen   im normalen Betriebe der Maschine keine Beeinflussung   des Magnetfeldes durch den Ankersttum   stattfindet, die die Betriebseigenschaft   des Motor ? verändert.   



   Es kann nützlich sein, anstatt   eines gewöhnlichen Schalters zum Einschalten des Anker-   stromes einen Schalter mit Schutzwiderstand zu   verwenden. Dieser besitzt wegen semer ausser@

 eine erhebliche Raum- und Gewichtsersparms erzielt, die bei vielen Fahrzeugen von ausschlaggebender Bedeutung für   die   Anwendung des Systames ist. Der grösste Vorteil liegt aber darm begründet, dass die Manövrierfähigkeit des Fahrzeuges ausserordentlich verbessert wird. weil die Anlass- oder Umnsteuerzeit des Propellers auf wenige Sekunden herabgedrückt wird.   während   sie bei den bisherigen Antriebsarten gewöhnlich erhebliche Bruchteile von Minuten betrug.

   The entire current surge is therefore always used to accelerate or decelerate the propeller, so that this extremely long can be brought to high or low speed.



  The duration of the current surge that occurs is limited to such an extent that the windings of the motor are not subjected to excessive heating. The commutation of the strong current surge also takes place without sparks, since the armature speed is only low when it occurs and, in addition, the heating of the coals up to the spark takes a certain amount of time.



   In order to be independent of the large time constant of the excitation circuit and the resulting slow increase in the field, the excitation of the motors will be kept permanently connected to voltage so that the full field strength already prevails when the armature current is switched on.



   Due to the constant self-induction of the armature circuit, the current begins at the moment of switch-on with the value zero, but only reaches its maximum value after a very short time. only to then fall again due to the rapidly increasing speed of the motor and finally return to its normal value. It can happen. that the self-induction of the armature in large machines is so low that the maximum current surge becomes excessively large and results in damage to the motor and the supplying accumulator battery. To avoid such interference. a self-induction coil is to be connected upstream in the armature circuit, which allows the speed of the current rise and the maximum of the current to be limited as desired.



   It is very advantageous to move the self-induction into the machine itself, by providing the field magnets with a compounding winding through which the armature current flows. In this case, not only does the pure self-induction effect occur, but the current surge is also weakened by the fact that the strong field means that even when there is little shock! of the motor already greater counter-electromotive forces are induced. It is particularly expedient not to connect the compounding winding directly in series with the armature current, but rather to dome it inductively with the armature taper by means of a transformer.



  This achieves the effect that only the strong rise in the current at the beginning of the acceleration period acts on the field of the motor and thus on the Gfgen EMF. on the other hand, that in normal operation of the machine there is no influence of the armature on the magnetic field, which affects the operating characteristics of the motor? changed.



   It can be useful to use a switch with a protective resistor instead of an ordinary switch to switch on the armature current. This has because of semer except @
 EMI2.1
 A considerable saving in space and weight is achieved, which is of decisive importance for the use of the system in many vehicles. The biggest advantage, however, is that the maneuverability of the vehicle is greatly improved. because the starting or reversing time of the propeller is reduced to a few seconds. while it was usually considerable fractions of minutes with previous types of drive.
