Erfindungsgemäß wird der Generator gebildet durch einen Rotor 1, und innerhalb des zylindrischen Teiles befin den sich die Polkerne 11 (am Rotorpol), um die herum die Erregerspulen 6 gewickelt sind, wobei ferner die rohr förmige Nabe 3 und die Verkeilung 5 vorgesehen sind, die den Rotor 1 auf der Achse 15 des Dieselmotors 16 fest halten.According to the generator is formed by a rotor 1 , and within the cylindrical part are the pole cores 11 (at the rotor pole) around which the excitation coils 6 are wound, furthermore the tubular hub 3 and the wedge 5 are provided, which hold the rotor 1 firmly on the axis 15 of the diesel engine 16 .
Der Strom vom Negativpol erreicht die Erregerspulen 6 des Rotors 1 durch Erde, die beispielsweise vom Rotor 1 selbst aufgenommen wird, während der Negativpol durch eine Bronzescheibe 8 als Antifriktions-Beilagscheibe und eine konventionelle Bürste 2 geleitet wird, wobei dieser Positivpol von einem herkömmlichen elektronischen Reg ler 12 gespeist wird.The current from the negative pole reaches the excitation coils 6 of the rotor 1 through earth, which is received, for example, by the rotor 1 itself, while the negative pole is passed through a bronze disc 8 as an anti-friction washer and a conventional brush 2 , this positive pole being guided by a conventional electronic regulator ler 12 is fed.
Der Erreger oder Induktor des Stators 9 wird durch eine ringförmige Packung einer herkömmlichen Magnet platte gebildet, an deren Rand sich die Wicklungen bzw. Spulen 10 befinden, die den variablen Hochfrequenz strom erzeugen und tragen.The exciter or inductor of the stator 9 is formed by an annular packing of a conventional magnetic plate, on the edge of which are the windings or coils 10 which generate and carry the variable high-frequency current.
Diese Induktorpackung (Stator 9) wird durch Gewindebol zen 13 als Befestigungsschrauben am stationären Teil des Dieselmotors 16 durch einen geeigneten Lagerkör per 14 gehalten.This inductor pack (stator 9 ) is held by threaded bolts 13 as fastening screws on the stationary part of the diesel engine 16 by a suitable bearing body by 14 .
Wie in jedem herkömmlichen Generator induziert der Mag netismus, der vom Rotorpol 11 ausströmt, wenn dieser sich um den Kern des Stators 9 dreht, einen Schwach strom in den Spulen 10. Dieser Strom wird zu den Spu len 6 des Rotors 1 durch den herkömmlichen elektro nischen Regler 12 zu rückgeführt, so daß auf diese Weise das Magnetfeld der Rotorpole 11 verstärkt wird, bis die in die Spulen 10 des Stators induzierte Span nung die vorbestimmte Nominalgröße erreicht. Der Regler 12 hält die Erregung aufrecht, die sicherstellt, daß die an den Spulen 10 erzeugte Spannung von der vorbe stimmten Nominalgröße ist, unabhängig von der Ladung und Geschwindigkeit innerhalb bestimmter Grenzen, d. h. den Arbeitsgeschwindigkeitsgrenzen des Generators selbst.As in any conventional generator, the magnetism that flows from the rotor pole 11 when it rotates around the core of the stator 9 induces a weak current in the coils 10 . This current is fed back to the spools 6 of the rotor 1 by the conventional electronic controller 12 , so that in this way the magnetic field of the rotor poles 11 is amplified until the voltage induced in the coils 10 of the stator reaches the predetermined nominal size. The controller 12 maintains the excitation, which ensures that the voltage generated on the coils 10 is of the predetermined nominal size, regardless of the charge and speed within certain limits, ie the operating speed limits of the generator itself.
Unter diesen Bedingungen und wenn der Generator einmal mit einem Motorelement bzw. dem Dieselmotor 16 gekop pelt ist (vorzugsweise thermisch und fähig, innerhalb vor eingestellter Grenzen seine Geschwindigkeit entsprechend den Erfordernissen zu variieren), ist es möglich, eine Hochfrequenzelektrizität zu erzeugen, die in Überein stimmung mit der Geschwindigkeit des Generators variabel ist, wobei der erzeugte Strom durch herkömmliche Mittel gleichgerichtet wird, um ihn anschließend bei Normalspan nung und -frequenz, vorzugsweise 200 V und 50/60 Hz, schwingen zu lassen, so daß er unter Verwendung eines ge eigneten Verteilernetzwerkes Verbraucherelementen, wie zum Beispiel Beleuchtung, Heizung, elektromechanischen Einrichtungen, Sendern usw., zuzuführen, unter Änderung der Frequenz des Generators entsprechend der erforder lichen Belastung und mit geeigneten Mitteln.Under these conditions and once the generator is coupled to a motor element or the diesel engine 16 (preferably thermally and capable of varying its speed according to requirements within preset limits), it is possible to generate high frequency electricity which is in agreement mood is variable with the speed of the generator, the generated current is rectified by conventional means in order to then vibrate it at normal voltage and frequency, preferably 200 V and 50/60 Hz, so that it can be used using a suitable ge Distribution network supply consumer elements, such as lighting, heating, electromechanical devices, transmitters, etc., by changing the frequency of the generator according to the required load and with suitable means.
Außerdem läßt sich der beigefügten Zeichnungsfigur ent nehmen, daß die Antifriktions-Beilagscheibe 8 so ange bracht ist, daß sie in permanentem Kontakt mit der Nabe 3 und der Bürste 2 ist, die im induzierten Stator 9 sitzt.In addition, the attached drawing figure ent ent that the antifriction washer 8 is placed so that it is in permanent contact with the hub 3 and the brush 2 , which sits in the induced stator 9 .
Weil bei dieser erfindungsgemäßen Ausführung der Gene ratorrotor auf der Kurbelwelle des Dieselmotors montiert ist, können wesentliche Einsparungen von Teilen erzielt werden, da alle Arten von elastischen Kupplungen/Lage rungen entfallen, wodurch die Kosten reduziert werden und eine vereinfachte Wartung erreicht wird.Because in this embodiment of the genes according to the invention rator rotor mounted on the crankshaft of the diesel engine significant savings in parts can be achieved be because of all kinds of flexible couplings / location There is no need for savings, which reduces costs and simplified maintenance is achieved.
