Description
Zylinderspule für elektrische Maschinen Für..elektrische Maschinen, insbesondere kleinere Gleichstrommotoren oder Gleichstromgeneratoren werden Zylinderspulen eingesetzt, wenn eine.mügliehst geringe Trägheit des Rotors eine große Rolle spielt. Diese spezifische Form einer Spule bietet darüber hin.-aus die Möglichkeit, die im allgemeinen entstehenden.Wickelköpße zu vermeiden und damit für kleine Gleichstrommaschinen ungewöhnlich hohe Wirkungsgrade zu erzielen. Cylinder coil for electrical machines Cylinder coils are used for electrical machines, especially smaller DC motors or DC generators, if the rotor's inertia is as low as possible. This specific form of a coil also offers the possibility of avoiding the winding heads that generally arise and thus achieving unusually high levels of efficiency for small DC machines.
In der deutschen Patentschrift Nr. 1 188 709 ist die Herstellung einer solchen Spule be= schrieben. Diese Heretellungsart besitzt jedoch den Nachteil, daß man zum Wickeln teure Spezialmaschinen braucht. Diesen Nachteil hat ein anderer Hersteller zu umgehen versucht, der seohskantf örmige Vindungen auf einen entsprechenden Dorn mittels einer gewöhnlichen Wickelmaschine herstellt und diese zu einer Zylinderfora biegt und mit Giessharz verbackt.In the German patent specification No. 1 188 709 is the production of a such a coil described. However, this type of production has the disadvantage that you need expensive special machines for winding. This disadvantage Another manufacturer tried to bypass the square-shaped connections on a corresponding mandrel by means of an ordinary winding machine and bends it into a cylindrical shape and baked it with casting resin.
Hierbei traten jedoch ebenfalls größere Leiterverluste. auf, weil die Wicklung keine optimale Form aufwies.However, this also resulted in greater conductor losses. on because the winding was not optimally shaped.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden und eine optimale Gestalt der Wicklung zu schaffen. Erfindungsgemäß ist die Zylinderspule so ausgebildet und hergestellt, daß der die Zylinderspule bildende Leiter rautenförmig, Windung neben Windung liegend anuÄhernd einen Leiterdurchmesser versetzt gewickelt, zu einem Zylinder gebogen und zu einer Einheit verbunden ist. Anhand@der Zeichnungen sei der Erfindungs-Bedanke näher erläutert.The invention is based on the object of avoiding this disadvantage and to create an optimal shape of the winding. According to the invention is the solenoid designed and manufactured in such a way that the conductor forming the solenoid is diamond-shaped, Winding next to winding approximating one conductor diameter wound offset, is bent into a cylinder and connected to form a unit. Based on Drawings will be explained in more detail of the invention.
Fig. i zeigt die bekannte eechskantförmige Wicklung, Fig. 2 zeigt ein Ausführungsbeispiel der erßind'ungsgemäßen rautenförmigen Wicklung' Fig. 3 demonstriert die Verkürzung der Leiterlänge zwecks Reduktion der ohmsahen Verluste bzw. Verbesserung des Wirkungsgrades gegenüber der bekannten Wicklung nach Fig. 1Fig. I shows the known hexagonal winding, Fig. 2 shows an exemplary embodiment of the diamond-shaped winding according to the invention is demonstrated in FIG the shortening of the conductor length in order to reduce the resistive losses or improve them the efficiency compared to the known winding according to FIG. 1
