  Elektrische Maschine mit Nutenwicklung und Dämpferspulen.

 EMI2.1 
 Ankers nicht an ein bestimmtes Breitenmass gebunden ist, wie aus Fig. 4 hervorgeht.'
Auch eine Kommutierungsspule nach Fig. 6 und 7 kann eine vorzügliche, fast streuungsfreie Verkettung ergeben. Diese Spule besteht aus einer Reihe hintereinander geschalteter Windungen, die nicht unterhalb der Ankerwicklung w in der Nut konzentriert, sondern neben dieser Wicklung bis zur Höhe der ganzen Ankerwicklung ausgebreitet werden. Bei dieser Anordnung der Dämpferspulen wird zwar die Nut etwas breiter als bei den vorher beschriebenen Anordnungen ausfallen. Da aber nur die innere Spulenseite für die Wegnahme von Nutenraum in Betracht kommt, ist die Anordnung in manchen Fällen noch zulässig. 



   PATENT-ANSPRÜCHE :

  Electric machine with slot winding and damper coils.
 EMI1.1
 

 <Desc / Clms Page number 2>

 
 EMI2.1
 Anchor is not tied to a certain width, as can be seen from FIG.
A commutation coil according to FIGS. 6 and 7 can also result in an excellent, almost scatter-free concatenation. This coil consists of a series of turns connected one behind the other, which are not concentrated in the groove below the armature winding w, but are spread out next to this winding up to the height of the entire armature winding. With this arrangement of the damper coils, the groove will be somewhat wider than in the arrangements described above. However, since only the inner side of the coil can be used to remove slot space, the arrangement is still permissible in some cases.



   PATENT CLAIMS:
 EMI2.2

Claims (1)

Seiten (Fig. 4). Pages (Fig. 4). 3. Elektrische Maschine nach Anspruch 1, dadurch gekennzeichnet, dass die Höhe (a) der innen liegenden Seiten der Dämpferspulen und die Breite (il) der radialen Seiten dieser Spulen oder nur eine dieser beiden Dimensionen grosser ist als die Höhe (b) der aussen liegenden Seiten der Dämpferspulen. 3. Electrical machine according to claim 1, characterized in that the height (a) of the inner sides of the damper coils and the width (il) of the radial sides of these coils or only one of these two dimensions is greater than the height (b) of the outside lying sides of the damper coils. 4. Elektrische Maschine nach Anspruch 1, dadurch gekennzeichnet, dass die innen liegenden Seiten der Dämpferspulen neben der Ankerwicklung (v, w) ausgebreitet liegen (Fig. 6). 4. Electrical machine according to claim 1, characterized in that the inner sides of the damper coils next to the armature winding (v, w) are spread out (Fig. 6). 5. Elektrische Maschine nach Anspruch 1 bis 4, dadurch gekennzeichnet, dass die aussen liegenden Seiten der Dämpferspulen durch diese und die inneren Spulenseiten umschliessende Bindedrähte (r)' oder durch Klammern an den Verschlusskeilen im Bereich der Ankernuten gegen die Fliehkräfte geschützt sind. 5. Electrical machine according to claim 1 to 4, characterized in that the outer sides of the damper coils are protected against centrifugal forces by binding wires (r) 'surrounding them and the inner coil sides or by clips on the locking wedges in the area of the armature grooves. 6. Elektrische Maschine nach Anspruch 1 bis 5, dadurch gekennzeichnet, dass die Wirbelstrombildung in den Aussenseiten der Dämpferspulen durch Verdrillen oder Verschränken der Seiten od. dgl. verhindert ist. EMI2.3 6. Electrical machine according to claim 1 to 5, characterized in that the formation of eddy currents in the outer sides of the damper coils by twisting or entangling the sides or the like is prevented.
