 Zeitkonstante   T,   des   Gcsamtstromkroises gteich   der   eines Teilpoles 21. Wenn   man nämlich zwei gleiche Selbstinduktionsspulen hintereinander schaltet, so ist bekanntlich die resultierende Selbstinduktion des Stromkreises gleich der doppelten Selbstinduktion einer Spule.

 gewählt werden, ebenso die Spannung, für die man die einzelnen Magnetspulen wickelt ; denn wenn man z. B. einen Pol für doppelte Spannung wickelt, so erhält er die doppelte   Windungszahl   vom halben Querschnitt, also wird n. q und damit l'konstant. 



   Die Unterteilung der Magnetpole in zwei oder mehrere Gleichpole kann in tangentialer (Fig. 1 und 2) oder in achsialer Richtung (Fig. 5 und 6) geschehen. Ebenso ist es möglich,

 Verwendung eines Ankers anzuordnen. Die Teilung der Pole kann auch in tangnntialer und achsialer Richtung zugleich erfolgen (Fig. 1 und 4). 



   Besonders wertvoll ist diese Anordnung beim elektrischen Betrieb von reversierbaren Walzenstrassen, wo zum Anlassen der Maschine nur eine sehr kurze Zeit (1-2 Sekunden) zur Verfügung steht. 



   PATENT-ANSPRÜCHE : 
1. Einrichtung zur Beschleunigung der Erregung elektrischer Maschinen, gekennzeichnet durch die Teilung eines jeden Feldmagnetpoles in mehrere Gleichpole, deren jeder die gleiche Windungszahl wie der ursprüngliche Pol hat, zu dem Zwecke, die Zeitkonstante der Erregerwicklung zu verringern.

 Time constant T, of the total current circuit equals that of a partial pole 21. If you switch two identical self-induction coils in series, the resulting self-induction of the circuit is known to be equal to twice the self-induction of a coil.

 can be selected, as well as the voltage for which the individual magnetic coils are wound; because if you z. If, for example, a pole winds for double the voltage, it receives twice the number of turns of half the cross-section, so n. Q and thus l 'becomes constant.



   The subdivision of the magnetic poles into two or more identical poles can take place in a tangential (FIGS. 1 and 2) or in an axial direction (FIGS. 5 and 6). It is also possible
 EMI2.9
 Use an anchor to arrange. The division of the poles can also take place in the tangential and axial direction at the same time (FIGS. 1 and 4).



   This arrangement is particularly valuable for the electrical operation of reversible roller lines, where only a very short time (1-2 seconds) is available to start the machine.



   PATENT CLAIMS:
1. Device for accelerating the excitation of electrical machines, characterized by the division of each field magnetic pole into several equal poles, each of which has the same number of turns as the original pole, for the purpose of reducing the time constant of the excitation winding.
