    Fahrzeug-Wendepol-Dynamomaschine   zur Stromerzeugung gleicher Polarität bei wechselnder
Drehrichtung, deren   Magnetwieklung   von einer Erregermaschine gespeist wird.

 des Magnetfeldes der Hauptdynamo statt. Während somit bei der bekannten Einrichtung die Magnetwicklung der Hauptdynamo von der Erregermaschine allein gespeist wird, wobei deren Erregerwicklung an die Bürsten der Hauptdynamo angeschlossen ist, wird im Gegensatz hiezu nach vorliegender Erfindung gleichzeitig sowohl die Magnetwicklung 3 der Hauptdynamo als auch die Erregerwicklung 15 der Erregermaschine von letzterer gespeist, in der Weise, dass in beiden   Drehrichtungen   die von der Erregermaschine erregte Erregerwicklung 15 von einem Strom gleichbleibender Richtung durchflossen wird,

   die Stromrichtung durch die Magnetwicklung 3 jedoch bei jedem Wechsel der Drehrichtung gewechselt wird. 



   In der Abbildung ist die Aufrechterhaltung des Richtungssinnes des Erregerstromes in der Erregerwicklung 15 beim Wechsel der Drehrichtung durch eine selbsttätig wirkende Bürstenverstellung um eine Polteilung dargestellt. Neben den verstellbaren Bürsten 13, 14 angeordnet befinden sich auf dem Kollektor 9 die feststehenden Bürsten 11, 12. Es liegen beide Bürstenpaare nach erfolgtem Wechsel der Drehrichtung stets in der neutralen Zone der Erregermaschine. Dadurch, dass die Erregerwicklung 15 unmittelbar an die verstellbaren Bürsten 13, 14 angeschlossen ist, wird ausser den bereits erwähnten Vorteilen, die in der sicheren und rascheren Erregung und dem günstigeren grösseren   Regulierbereieh   bestehen, auch der Vorteil erreicht, dass die Erregerwicklung 15 für eine niedrigere Spannung hergestellt werden kann.

   Weil die Klemmenspannung der Dynamo in Anbetracht ihrer grossen Leistung entsprechend hoch gewählt werden muss, um einen Strom kleinerer Grösse zu erhalten, können die Erregermaschine bzw. die von ihr gespeisten Wicklungen 3, 15 daher für eine wesentlich kleinere Spannung ausgeführt werden. Dies ist besonders günstig für die grössere Haltbarkeit der Reglerkontakte, besonders wenn ein Vibrationsregler die Regelung der Spannung und des Stromes der Hauptdynamo besorgt, deren Regulierwiderstand sich im   Nebenschlusszweig     13-14-15-13   befindet. Nach Überschreiten der Mindestdrehzahl der Hauptdynamo nimmt die Spannung im Nebenschlusszweig ab, dagegen ist sie in der bekannten Einrichtung gleich der Grösse der geregelten Klemmenspannung der Dynamo. 



   PATENT-ANSPRÜCHE :
1.   Fahrzeug-Wendepol-Dynamomaschine   zur Erzeugung gleicher Polarität bei wechselnder Drehrichtung mit einer gleichsinnig mit dieser angetriebenen Erregermaschine, dadurch gekennzeichnet, dass gleichzeitig sowohl die Magnetwicklung (3) der Hauptdynamo als auch die Erregerwicklung (15) der Erregermaschine von letzterer gespeist wird, in der Weise, dass in beiden Drehrichtungen die Erregerwicklung der Erregermaschine von einem Strom gleichbleibender Richtung durchflossen wird, die Stromrichtung durch die Magnetwicklung der Hauptdynamo jedoch bei jedem Wechsel der Drehrichtung gewechselt wird.

    Vehicle reversing pole dynamo machine to generate electricity with the same polarity when the

 of the magnetic field of the main dynamo. While in the known device the magnet winding of the main dynamo is fed solely by the exciter, with its exciter winding being connected to the brushes of the main dynamo, in contrast to this, according to the present invention, both the magnet winding 3 of the main dynamo and the exciter winding 15 of the exciter of The latter is fed in such a way that the excitation winding 15 excited by the excitation machine is traversed by a current of constant direction in both directions of rotation,

   however, the direction of current through the magnet winding 3 is changed each time the direction of rotation is changed.



   The figure shows the maintenance of the direction of the excitation current in the excitation winding 15 when the direction of rotation is changed by an automatically acting brush adjustment by one pole pitch. Arranged next to the adjustable brushes 13, 14 are the fixed brushes 11, 12 on the collector 9. After the direction of rotation has been changed, both pairs of brushes are always in the neutral zone of the exciter. The fact that the excitation winding 15 is directly connected to the adjustable brushes 13, 14, in addition to the advantages already mentioned, which consist in the safer and faster excitation and the cheaper, larger regulation range, also has the advantage that the excitation winding 15 for a lower Tension can be established.

   Because the terminal voltage of the dynamo has to be selected to be correspondingly high in view of its high power in order to obtain a current of smaller magnitude, the exciter machine or the windings 3, 15 fed by it can therefore be designed for a significantly lower voltage. This is particularly beneficial for the greater durability of the regulator contacts, especially if a vibration regulator regulates the voltage and current of the main dynamo, the regulating resistor of which is located in the shunt branch 13-14-15-13. After the minimum speed of the main dynamo is exceeded, the voltage in the shunt branch decreases, but in the known device it is equal to the size of the regulated terminal voltage of the dynamo.
