PATENTAMT.PATENT OFFICE.
In der Patentschrift 229027 ist eine Einrichtung zur Aufhebung der Remanenz bei Anlaßmaschinen für Gleichstrom, insbesondere bei solchen für Panzerturmschwenkwerke, beschrieben. Diese Einrichtung besteht im wesentlichen darin, daß jedesmal beim Auftreten eines Spannungsunterschiedes zwischen der dem angetriebenen Motor zugeführten Spannung und der am Steuerhebel eingestellten Erregerspannung der Anlaßmaschine eine Hilfsmaschine, deren Feldmagnet durch diese Spannungsdifferenz erregt wird, so auf die Magneterregung der Anlaßmaschine einwirkt, daß der erwähnte Spannungsunterschied verschwindet.In the patent specification 229027 a device for canceling the remanence is at Starting machines for direct current, especially those for armored turret slewing gear, are described. This device essentially consists in the fact that each time one occurs Voltage difference between the voltage supplied to the driven motor and the excitation voltage of the starting machine set on the control lever an auxiliary machine, whose field magnet is excited by this voltage difference, so on the magnet excitation the starting machine acts that the mentioned voltage difference disappears.
Den Gegenstand der Erfindung bildet eine Vereinfachung dieser Einrichtung. Diese besteht darin, daß unter Fortfall der Hilfsmaschine auf der Anlaßmaschine selbst eine Hilfserregerwicklung angeordnet ist, welche jedesmal beim Auftreten eines Spannungsunterschiedes zwischen der dem angetriebenen Motor zugeführten Spannung und der am Steuerhebel eingestellten Erregerspannung der Anlaßmaschine so auf das Magnetfeld der Anlaßmaschine einwirkt, daß der erwähnte Spannungsunterschied verschwindet.The subject of the invention is a simplification of this device. This exists in that with the omission of the auxiliary machine on the starting machine itself an auxiliary excitation winding is arranged, which each time a voltage difference occurs between that of the driven motor supplied voltage and the excitation voltage of the starting machine set on the control lever so acts on the magnetic field of the starting machine that the aforementioned voltage difference disappears.
Die Zeichnung zeigt ein Ausführungsbeispiel. Übereinstimmende Teile sind in der gleichen Weise bezeichnet wie beim Hauptpatent und bedürfen daher keiner näheren Beschreibung.The drawing shows an embodiment. Matching parts are in the same In the same way as in the main patent, they do not require any further description.
Die Anlaßmaschine α besitzt außer der vom Steuerhebel beeinflußten Feldwicklung δ noch eine Hilfsfeldwicklung i1. Diese ist in die Leitung / geschaltet, welche eine Klemme des Ankers α der Anlaßmaschine und eine Klemme der Feldwicklung b verbindet. Die beiden anderen Klemmen sind durch die Leitung m verbunden. In einer der beiden Leitungen, z. B. I, liegt noch der Regelungswiderstand k. Der Schaltsinn der Hilfswicklung i1 ist so zu wählen, daß sie die Feldwicklung b unterstützt, wenn die Spannung der Anlaßmaschine geringer ist als die am Steuerhebel eingestellte Erregerspannung, daß sie dagegen im umgekehrten Falle der Feldwicklung b entgegenwirktIn addition to the field winding δ influenced by the control lever, the starting machine α also has an auxiliary field winding i 1 . This is connected to the line /, which connects a terminal of the armature α of the starting machine and a terminal of the field winding b. The other two terminals are connected by the line m . In one of the two lines, e.g. B. I, there is still the control resistor k. The switching direction of the auxiliary winding i 1 is to be selected so that it supports the field winding b when the voltage of the starting machine is lower than the excitation voltage set on the control lever, but in the opposite case it counteracts the field winding b
