Description

  

  Wechselstrom-Kollektormotor.    Vorliegende Erfindung bezieht sich auf  Motoren nach dem Patentanspruch des Haupt  patentes mit mindestens zwei getrennten,  magnetisch und elektrisch möglichst gleich  auf dem Ankerumfang angeordneten Anker  wicklungen, welche zur Erzielung einer höhe  ren Spannung in Serie geschaltet sind.  



  Hierbei soll erfindungsgemäss eine Ver  einfachung, Materialersparnis und Reduktion  der Verluste in den Sperrkreisen dadurch  erzielt werden, dass nur jedem zweiten  Bürstenpol jedes Kollektorkranzes ein Sperr  kreis zugeordnet ist, während die miteinander  übereinstimmenden Bürsten der andern Pole  in Serie geschaltet sind.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist in der Zeichnung schematisch  dargestellt.  



  In der Zeichnung sind S1 und S2 zwei  getrennte Ankerwicklungen, welche magne  tisch und elektrisch möglichst gleich auf dem  Anker des Motors angeordnet und je mit  einem Kollektor K1 bezw. K2 verbunden    sind. Jeder Kollektor hat abwechselnd auf  einanderfolgende Wirk- und Blindlamellen  1, 3, 5, 7 . . . bezw. 2, 4, 6, 8 . . . Jeder  Bürstenpol jedes Kollektors hat zwei um  1,5 Lamellenbreite voneinander entfernte  Bürsten, und zwar der Kollektor<B>Ei</B> die  Bürstenpaare B1, B1' und B2, B2', der  Kollektor K2 die Bürstenpaare B3, B3' und  B4, B4. An die Bürstenpaare B1, B1' und  <I>B4, B4'</I> sind Sperrkreise angelegt, welche  je in Parallelschaltung je einen Kondensator  C bezw. C4 und eine Drosselspule L1 bezw.  C4 enthalten, und die Zuführung bezw. Ab  leitung des Stromes ist an den Mittelpunkt  O der beiden Drosselspulen angeschlossen.

    Die beiden andern Bürstenpaare sind in  Serie geschaltet, und zwar ist die Bürste B2  mit der Bürste B3', die Bürste B2' mit der  Bürste B3 unmittelbar verbunden, so dass  sich im Linienzuge die im Stromkreis     B2-          Spule,    II-Bürste, B2'-Bürste, B3-Spule,     III-          Bürste        Bs'    zurück nach Bürste     B2    in den  Ankerspulen     II    und     III    induzierten Spannungen      gegenseitig aufheben. Es genügt deshalb,  wenn bloss zwei Bürstenpaare mit einem  Sperrkreis versehen sind.



  AC collector motor. The present invention relates to motors according to the claim of the main patent with at least two separate, magnetically and electrically as possible the same armature windings arranged on the armature circumference, which are connected in series to achieve a higher voltage.



  Here, according to the invention, a simplification, material savings and reduction in losses in the blocking circuits should be achieved in that only every second brush pole of each collector ring is assigned a blocking circuit, while the matching brushes of the other poles are connected in series.



  An embodiment of the subject invention is shown schematically in the drawing.



  In the drawing, S1 and S2 are two separate armature windings, which magne table and electrical as possible the same on the armature of the motor and each with a collector K1 respectively. K2 are connected. Each collector has alternating active and blind lamellae 1, 3, 5, 7. . . respectively 2, 4, 6, 8. . . Each brush pole of each collector has two brushes separated by 1.5 lamella width, namely the collector <B> Ei </B> the brush pairs B1, B1 'and B2, B2', the collector K2 the brush pairs B3, B3 'and B4 , B4. Blocking circuits are applied to the pairs of brushes B1, B1 'and <I> B4, B4' </I>, each of which is connected in parallel to a capacitor C respectively. C4 and a choke coil L1 respectively. C4 included, and the feed respectively. From the line of the current is connected to the center point O of the two inductors.

    The other two pairs of brushes are connected in series, namely the brush B2 is directly connected to the brush B3 ', the brush B2' is directly connected to the brush B3, so that the circuit in the circuit B2 coil, II brush, B2 ' -Brush, B3 coil, III- brush Bs' back to brush B2 in the armature coils II and III cancel each other induced voltages. It is therefore sufficient if only two pairs of brushes are provided with a blocking circuit.
