PATENTAMT.PATENT OFFICE.
Bei Repulsionsmotoren tritt an zwei Punkten A und B des sekundären Bürstensystems ein Spannungsunterschied auf, welcher je nach den Betriebsverhältnissen in weiten Grenzen variiert.In repulsion motors, a voltage difference occurs at two points A and B of the secondary brush system, which varies within wide limits depending on the operating conditions.
Er ist wesentlich abhängig von der primären Spannung, von der sekundären Bürstenstellung und von der Tourenzahl oder von einzelnen dieser drei Größen, wenn die übrigen konstant bleiben.It is essentially dependent on the primary voltage and the secondary brush position and of the number of tours or of any of these three quantities, if the others stay constant.
Wird an diese beiden Punkte (Fig. i) ein geeigneter Hilfsmotor hm angelegt, so wird er von Strömen gleicher Periodenzahl durchflossen wie der Hauptmotor HM und übt Drehmomente aus, welche wesentlich von dem Spannungsunterschied an den Anschlußpunkten, also von den Betriebsverhältnissen des Hauptmotors abhängen. Mit Hilfe dieser Drehmomente soll nach vorliegender Erfindung die zur Regelung des Hauptmotors beweglich eingerichtete Bürstenbrücke verstellt werden. If a suitable auxiliary motor hm is applied to these two points (Fig. I), it is traversed by currents of the same number of periods as the main motor HM and exerts torques which essentially depend on the voltage difference at the connection points, i.e. on the operating conditions of the main motor. With the help of these torques, according to the present invention, the brush bridge, which is movably set up to control the main motor, is to be adjusted.
Als Beispiel einer Anwendung sei das Anlassen von Repulsionsmotoren bei Fernsteuerung angeführt (Fig. 2). Wird der Stator von fern ans Netz gelegt, so herrscht an den zwei Anschlußpunkten A und B des sekundären Bürstensystems die maximal dort auftretende Transformatorspannung. Der Hilfsmotor übt sein größtes Drehmoment aus und beginnt sofort mit der Betätigung des regelnden Apparates, z. B. mit der Verstellung der beweglichen Bürsten b, b. Mit größer werdender Bürstenverstellung α und zunehmender Tourenzahl des Hauptmotors nimmt die Spannung am Hilfsmotor ab und damit seine Tourenzahl bis zum Stillstand, wenn die Bürstenverstellung beendet ist. Auch die Kurzschließung des sekundären Teiles nach beendigter Bürstenverstellung mittels des Schalters K kann durch den Hilfsmotor geschehen. -As an example of an application, the starting of repulsion motors with remote control is given (Fig. 2). If the stator is connected to the grid remotely, the maximum transformer voltage occurring there prevails at the two connection points A and B of the secondary brush system. The auxiliary motor exerts its greatest torque and immediately starts operating the regulating apparatus, e.g. B. with the adjustment of the movable brushes b, b. As the brush adjustment α increases and the number of revolutions of the main motor increases, the voltage on the auxiliary motor decreases and thus its number of revolutions to a standstill when the brush adjustment is finished. The short-circuiting of the secondary part after the brush adjustment has been completed by means of switch K can also be done by the auxiliary motor. -
Weitere Anwendungen sind die Bewegung' der Bürsten (Regelung des primären oder sekundären Teiles) im Betrieb, sei es zur Aufrechterhaltung einer normalen Tourenzahl bei verschiedenen Belastungen, sei es zur Anpassung der Tourenzahl an die verschiedenen Belastungen, wobei je nachdem der Hilfsmotor von vornherein eingerichtet oder passend geschaltet oder eingestellt wird.Further applications are the movement of the brushes (regulation of the primary or secondary Part) in operation, be it to maintain a normal number of tours with different Loads, be it to adapt the number of tours to the various loads, depending on the auxiliary motor set up from the start or switched appropriately or is discontinued.
Fig. 3 zeigt den Anschluß eines Hilfsmotors an einen kompensierten Repulsionsmotor nach Latour.Fig. 3 shows the connection of an auxiliary motor to a compensated repulsion motor according to Latour.
