Description
Ankerwicklungen mit Stromwender für Gleichstrom., Wechselstrom oder Drehstrom werden häufig als Schleifenwicklung· mit 'einer Windung je Stromwendersteg ausgeführt Bei gegebener Maschinentype wird die Anzahl der Stromwendersteg© um so größer, je höher die IQemmenspannung ist, . und von einer bestimmten Spannung an wird die Breite der Stromwenderstegie unausführbar schmal. Die bekannte Wellenwicklung verringert die Anzahl der Stromwenderstege, erhöht aber die Spannung zwischen benachbarten Stegen und ist darum in vielen Fällen nicht zulässig. Das gleiche gilt auch für eine in anderem Zusammenhang bekanntgewordene Schleifen* wicklung, bei der die Stegzahl auf die Hälfte verringert, dafür aber die Spannung zwischen, benachbarten Stegen verdoppelt wird.Armature windings with commutator for direct current, alternating current or three-phase current are often called loop winding · with 'a Winding per commutator web. For a given machine type, the number of The commutator bridge © is larger, the higher the terminal voltage,. and from a certain Voltage on, the width of the commutator web becomes impracticably narrow. the known wave winding reduces the number of commutator bars, but increases the Tension between adjacent webs and is therefore not permitted in many cases. The same applies to loops that have become known in another context * winding in which the number of webs is reduced by half, but the tension between, adjacent webs is doubled.
Erfindungsgemäß ist die Anzahl der Stromwenderstege einer Schleifenwicklung ohne Erhöhung der Spannung zwischen benachbarten Stegen dadurch verringert, daß die Stege je zweier benachbarter Polteilungen fortgelassen sind und eine oder mehrereAccording to the invention, the number of commutator bars in a loop winding is without Increasing the tension between adjacent webs is reduced by the fact that the webs each have two adjacent pole pitches are omitted and one or more
S5 Gruppen benachbarter Ankierspulen, welche je einem Polpaar entsprechen, nicht unmittelbar, sondern über Ausgleichsleitungen mit Stromwenderstegen verbunden sind, Ausgleichsleitungen sind an sich bekannt. Im vorliegenden Falle muß ihr Querschnitt größer bemessen werden, als für den Ausgleich von Unsymmetrien nötig ist.S5 groups of neighboring anchor coils, which each correspond to a pair of poles, not directly, but via compensating lines with Commutator bars are connected, compensating lines are known per se. In the present case, their cross-section must be larger be dimensioned as is necessary to compensate for asymmetries.
Die Erfindung ist in der Zeichnung in beispielsweiser Ausführungsform veranschaulicht.The invention is illustrated in the drawing in an exemplary embodiment.
Die Abbildung zeigt eine erfindungsgemäße Wicklung für eine achtpolige Gleichstrommaschine mit den Polen N1-S1-N2-S2 usw. Der Anker hat 32 Nuten und ebenso viele Ankerspulen, die in vier Gruppen parallel geschaltet sind. Es sind daher 32 Ausgleichs-Verbindungen erforderlich, von denen je vier einen geschlossenen Ring· bilden. Von den Ankerspulen sind die einem Polpaar entsprechenden Spulen 9 bis 16 und die einem Polpaar entsprechenden Spulen 2 5 bis 32 nicht unmittelr bar, sondern über Ausgleichsverbindungen an Stromwenderstege angeschlossen. Der Stromwender hat daher nur 32/2= 16 Stege 1 bis 8 und 17 bis 24 und 8/2 = 4 Bürstenbolzen A3 B, C und D. The figure shows a winding according to the invention for an eight-pole DC machine with the poles N 1 -S 1 -N 2 -S 2 etc. The armature has 32 slots and the same number of armature coils, which are connected in parallel in four groups. 32 compensating connections are therefore required, four of which form a closed ring. Of the armature coils, the coils 9 to 16 corresponding to a pair of poles and the coils 2 5 to 32 corresponding to a pair of poles are not directly connected, but rather are connected to commutator webs via compensating connections. The commutator therefore only has 32/2 = 16 bars 1 to 8 and 17 to 24 and 8/2 = 4 brush pins A 3 B, C and D.
