Description

  

  Nutenwicklung für elektrische Maschinen.    Werden Nuten von bestimmter, normaler  Höhe mit Leiterbündeln von solchem Quer  schnitt belegt, dass zwischen Wicklung und  Nutenboden Spielraum entsteht, so wird letz  terer in der Regel mit einem Keil, zum Bei  spiel aus Holz, ausgestopft.  



  Bei dem gezeichneten Ausführungsbei  spiel der Erfindung ist dieser Keil a U-förmig  ausgebildet, so dass zwischen Wicklung b  und Eisen c ein Kühlkanal d entsteht. Diese  allenfalls auch Z- oder T-förmige Stabeinlage  kann zwecks Abstimmung der Stärke des    magnetischen Feldes aus magnetischem oder  unmagnetischem Material bestehen.



  Groove winding for electrical machines. If grooves of a certain, normal height are covered with conductor bundles of such a cross-section that there is clearance between the winding and the groove base, the latter is usually stuffed with a wedge, for example made of wood.



  In the illustrated Ausführungsbei, game of the invention, this wedge a is U-shaped so that a cooling channel d is created between winding b and iron c. This possibly also Z- or T-shaped rod insert can consist of magnetic or non-magnetic material in order to adjust the strength of the magnetic field.

Claims (1)

PATENTANSPRUCH: Nutenwicklung für elektrische Maschinen mit zwischen Nutenboden und Wicklung vor gesehenem Keil, dadurch gekennzeichnet, dass letzterer aus einem den Raum zwischen Wick- lung und Eisets nicht ausfüllenden Formstab bestellt. PATENT CLAIM: Grooved winding for electrical machines with a wedge provided between the groove base and the winding, characterized in that the latter orders from a shaped rod that does not fill the space between the winding and the ice set.
