Description
Kollktorlose Gleichstrommaschine Zusatz zur Anmeldung Aktenzeichen ........... (wird nach Bekanntwerden derselben mitgeteilt).Collatorless DC machine Addition to the registration file number ........... (will be communicated after the same becomes known).
In der Hauptanmeldung ist vorgeschlagen 1) die Wicklung der Maschine als Trommelankerwicklung auszubilden und dann durch Weiterschaltung der Speisepunnte eine Drehung dea magnetischen Feldes zu bewirken. 2) Soll zur Vereinfachung der Löschvorgänge eine Parallelwicklung galvanisch von der ersten getrennt sein.The main application proposes 1) the winding of the machine to be designed as a drum armature winding and then by switching on the feed point to cause a rotation of the magnetic field. 2) intended to simplify the Deletion processes a parallel winding must be galvanically separated from the first.
Gegenstand dieser Erfindung ist die Einsparung der Parallelwicklung, da die Ldsohung des vorherigen Schaltkreises durch Kondensatoren, welche parallel zu den Wicklungselementen der Schaltkreise liegen in Verbindung mit den weiterschaltenden Thyristoren bewirkt wird.The object of this invention is to save the parallel winding, because the solution of the previous circuit through capacitors, which are in parallel to the winding elements of the circuits are in connection with the further switching Thyristors is effected.
Die bisher bekannt gewordenen Vorschläge stellen alle Maschinen vor mit offenen Rotorwicklungen und haben daher schlechte Kommutierungseigenschaften und ebenfalls schlechte elektromaschinenbauliche Eigenschaften hinsichtlich der Ausnutzung des Eisens und des Kupfers.The proposals that have become known so far present all machines with open rotor windings and therefore have poor commutation properties and also poor electrical engineering properties in terms of Utilization of iron and copper.
In der beigefügten Figur ist das Schalt schema für die Speisung und Fortschaltung eines Trommelankers mit vier Speisepunkten dargestellt. Die Zahl der Speisepunkte kann in weiten Grenzen verändert werden. Die Spulengruppen des Ankers sind mit a1, a2, a3 und a4 bezeichnet. Die Strombahnen entsprechend mit 1E ( E = Eingang ) - 1A ( A = Ausgang ) analog dazu die Strombahnen 2 E - 2 A 3 E - 3 A 4 E - 4 A Die Schalt- und Löschvorgänge laufen folgendermaßgen. Ausgangspunkt möge 1 E und 1 d sein. Der nächste schritt sei dann 2 E - 2 A oder 4 E - 4 A für die entgegengesetzt. Drehrichtung.In the attached figure is the circuit diagram for the supply and Continuation of a drum armature with four feed points shown. The number of Feeding points can be changed within wide limits. The coil groups of the armature are denoted by a1, a2, a3 and a4. The current paths are marked with 1E (E = Input) - 1A (A = output) analogously to the current paths 2 I - 2 A 3 I - 3 A 4 E - 4 O The switching and deleting processes run as follows. Starting point may 1 E and 1 d. The next step is then 2 I - 2 O or 4 I - 4 O for the opposite. Direction of rotation.
Durch Zünden der Thyristoren des Schaltkreises 2 oder 4 werden die Thyristoren des Kreises 1 geläscht. Weiterhin löschen die Thyristoren des Schaltkreises 3 die von 2 usw. Die Maschine kann auch als Einankerformer betrieben werden, indem von verschiedenen Punkten der Wicklung welche um den gewünschten Phasenwinkel versetzt sind, die Wechsel oder Drehstrom- oder Mehrphasenspannungen abgenommen werden. Der Rotor braucht nicht zu rotieren sondern kann ohne Wicklung sein und dann stillstehen. Zur Verminderung der Streuung können Stator und Rotorblechpakete konisch geschichtet seinr so daß der Luftspalt ganz geschlossen ist.By triggering the thyristors of circuit 2 or 4, the Circuit 1 thyristors cleared. The thyristors of the circuit also clear 3 those of 2 etc. The machine can also be operated as a single anchor former by of different Points of the winding which around the desired Phase angles are offset, the alternating or three-phase or multi-phase voltages be removed. The rotor does not need to rotate but can without winding be and then stand still. To reduce the scattering, stator and rotor laminations can be used be conically layered so that the air gap is completely closed.
