Description
Durch die große Verbreitung des Ein-Due to the widespread use of
phasenkollektormotors ist die Vereinfachung der Bauart zugunsten leichter Herstellung, großer Betriebssicherheit und leichter In-Standstellung immer wichtiger geworden.phase collector motor is the simplification of the design in favor of easier production, high operational safety and easy maintenance have become more and more important.
Die Erfindung bringt nun gegenüber bereits bekannten Lösungen eine weitere wesentliche Vereinfachung. Sie bezieht sich auf die Ausbildung des Wicklungsraumes im Ständer, insbesondere von Maschinen der genannten Art, deren geblechter Eisenkörper ausgeprägte Pole und Wendepole besitzt und deren konzentrierte Erreger- und Wendepol wicklungen zum voraus fix und fertig gewickelt und isoliert und in die beiden Wicklungen gemeinsamen Nuten radial eingeschoben werden können. Zur günstigsten Raumausnützung und größten Vereinfachung setzt sich erfindungsgemäß der Querschnitt der beiden Wicklungen gemeinsamen Nuten zusammen aus zwei sich teilweise überdeckenden Trapezen, deren Größe und Form gleich ist dem für jede einzelne Wicklung erforderlichen Querschnitt und der zum Einschieben jeder Wicklung erforderlichen Bahn.The invention now brings about a further essential solution compared to already known solutions Simplification. It relates in particular to the formation of the winding space in the stator of machines of the type mentioned, the laminated iron body of which is pronounced Poles and reversing poles and their concentrated exciter and reversing pole windings wrapped and insulated beforehand and shared in the two windings Grooves can be inserted radially. According to the invention, it is used for the best utilization of space and the greatest possible simplification the cross-section of the two coils common grooves together from two partially overlapping trapezoids whose The size and shape is the same as the cross-section required for each individual winding and the path required to insert each winding.
Fig. ι zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes, Fig. 2 die geometrische Erzeugung der Nut für dieses Beispiel und Fig. 3 einen Querschnitt einer geteilten Erregerwicklung. Fig. Ι shows an embodiment of the subject matter of the invention, FIG. 2 shows the geometrical generation of the groove for this example and FIG. 3 shows a cross section of a divided field winding.
Die Erregerwicklung 1 allein mit ihrer Einlegebahn würde im Statorblechkörper 3 eine Nut mit dem Umriß 5, 6, 7, 8 (Fig. 2) erfordern, die Wendepolwicklung 2 allein einen Umriß 5, 9, 10, 8; beides zusammen ergibt den Nutenquerschnitt mit minimaler Fläche, die das Einlegen und Verkeilen der beiden fertigen Spulen ermöglicht.The excitation winding 1 alone with its insert track would be in the laminated stator body 3 Groove with the outline 5, 6, 7, 8 (Fig. 2) require the reversible pole winding 2 alone Outline 5, 9, 10, 8; both together result in the Groove cross-section with minimal area, which finish the insertion and wedging of the two Allows coils.
Durch geeignete Wahl des Spulenquerschnittes wird auch die Nutenöffnung 5 bis 8 nicht größer, als sie zur Vermeidung starker magnetischer Streuung ohnehin erforderlich ist.By a suitable choice of the coil cross-section, the slot opening 5 to 8 no larger than is necessary anyway to avoid strong magnetic scattering.
Außerdem könnte die Erregerwicklung in zwei getrennten Paketen 15, 16 der Fig. 3 fertig gewickelt und isoliert werden. Das Paket 15 könnte zuerst auf der einen Seite und nachher erst auf der anderen Seite eingeschoben werden, so daß die Nutenöffnung 5 bis S weniger als die Breite der ganzen Erregerspule aufweisen muß, wenn gleichzeitig die Wendepolspule entsprechend schmäler gemacht wird.In addition, the field winding could be in two separate packages 15, 16 of FIG ready to be wrapped and insulated. The package 15 could first be on one side and can only be inserted afterwards on the other side so that the groove opening 5 until S must have less than the width of the entire excitation coil, if at the same time the reversible pole coil is made correspondingly narrower.
Die Hohlräume 11 und 12 können mit Ausfüllkörpern versehen sein, die zweckmäßig ausThe cavities 11 and 12 can be filled with filling bodies be provided that expediently
