Die Erfindung betrifft Gleichstrommotoren, die ohne Anlaßwiderstand unmittelbar ans Netz angeschaltet werden. Bei solchen Motoren war man darauf bedacht, den Stromstoß beim Einschalten dadurch auf ein bestimmtes Maß zu begrenzen, daß sie außer den üblichen Feldwicklungen eine Hauptstromfeldwicklung (Anlaßwicklung) von hohem scheinbaren und Ohmscljen Widerstand erhielten, die währendThe invention relates to direct current motors that are directly connected to the motor without a starting resistor Be switched on. With such motors one was careful to avoid the electric shock when switching on thereby to limit to a certain level that they are outside of the usual Field windings a main current field winding (starting winding) of high apparent and Ohmscljen resistance received that during
ίο des Anlaufes durch einen beliebigen Nebenschluß überbrückt und damit geschwächt oder kurzgeschlossen wurde oder nach erfolgter Überbrückungauch abgeschaltet werden konnte. Die Erfindung richtet sich auf die Vervollkommnung derartiger Qleichstrommotoren zum Anlassen durch unmittelbares Anschalten ans Netz ohne Anlaßwiderstand; ihr Wesen besteht . darin, daß ' die Hauptstromfeldwicklung (Anlaßwicklung) aus Eisen oder einem anderen paramagnetischen Material hergestellt wird. Es ist zwar bekannt, Wicklungen elektrischer 'Maschinen aus Eisen anzufertigen, doch werden im vorliegenden Fall hierdurch noch besondere Vorteile erreicht. Diese bestehen darin, daß die Hauptstromfeldwicklung mit zur Leitung des Feldkraftlinienflusses herangezogen werden kann, wodurch eine Verringerung des übrigen Eisenquerschnittes an den Stellen, an welchen die Wicklung liegt, möglich ist, und somit eine Verkleinerung des Maschinengewichtes bewirkt wird. Außerdem kann wegen der größeren Wärmekapazität. der Eisenwicklung die Häufigkeit des Anlaufens erhöht und die Anlauf dauer vergrößert werden.ίο the start-up by any shunt bridged and thus weakened or short-circuited, or even after bridging has taken place could be switched off. The invention is directed to perfecting such QDC motors for Starting by connecting directly to the mains without starting resistor; their essence consists . in that 'the main current field winding (starting winding) made of iron or another paramagnetic material is produced. Although it is known to have electrical windings 'Making machines out of iron, but in the present case this makes them even more special Benefits achieved. These consist in that the main current field winding is also used to conduct the field force line flow can be, as a result of which a reduction in the remaining iron cross-section at the points which the winding lies, is possible, and thus a reduction in the weight of the machine is effected. Also, because of the greater heat capacity. the iron winding the frequency of start-up can be increased and the start-up time extended.
Die Hauptstromfeldwicklurig aus Eisen wird unmittelbar auf die Kerne der Hauptpole gewickelt oder auf das Joch. In letzterem Falle ist noch ein weiterer Vorteil durch die leichtere Abkühlbarkeit der Wicklung sowie durch die größere mittlere Windungslänge gegeben. Letzterer Umstand begünstigt in manchen Fällen die Einhaltung einer bestimmten Windungszahl bei einem bestimmten Widerstand.The main current field winding made of iron is wound directly onto the cores of the main poles or on the yoke. In the latter case, there is another advantage due to the easier cooling of the winding as well as through given the greater mean winding length. The latter circumstance favors in some Cases compliance with a certain number of turns at a certain resistance.
