Abstract
Description
Synchrongenerator mit Permanentntagne+.l^v.fer, Halbleitergleichrichtern und eingebautem PolamschalterSynchronous generator with permanent magnet + .l ^ v.fer, semiconductor rectifiers and built-in pole switch
Bekanntlich ist die Polarität von Synchrongeneratoren mit Permanentmagnetläufern und Halbleitergleichrichtung drehrichtungsunabhängig. Dieser Mangel konnte bisher nur durch Einbau von Umschaltern behoben werden, welche mittels Freilaufsperrtrieben bei Drehrichtungsumkehr von der Antriebskraft des Generators mit betätigt wurden.The polarity of synchronous generators with permanent magnet rotors is well known and semiconductor rectification independent of the direction of rotation. So far, this deficiency has only been resolved by installing changeover switches be remedied, which by means of freewheel locking drives Reversal of the direction of rotation were actuated by the driving force of the generator.
Abgesehen von der verhältnismäßig großen Verzögerung erfolgt die Umschaltung infolge der vielen zu bewegenden Getriebe- und Schalterteile stoßweise, also z.B. bei schwachen tachometrischen Generatoren nicht rückwirkungsfrei. Diese Nachteile entfallen, wenn in die Generatoren Vorrichtungen gemäß dieser Erfindung eingebaut werden. -Apart from the relatively long delay, the changeover takes place as a result of the large number of gear and switch parts to be moved intermittently, e.g. with weak tachometric generators, not free of retroactive effects. These disadvantages do not apply if devices according to this invention are incorporated into the generators. -
Abbildung 1, 2 und 3 lassen zwei Ausführungsbeispiele des Erfindungsgegenstandes erkennen. Die Kontaktfedern a sind isoliert am Stator des Generators b, die Gegenkontakte c isoliert an einem, die Achse d des Generators konzentrisch umgebenden, gehärteten Stahlring e befestigt. Dieser Ring ist entweder bei f verdrehbar im Stator gelagert oder beispielsweise von Kugeln g getragen, welche, wie bei Wälzlagern« auf der Generatorachse umlaufen. Im Falle des zuerst Genannten sitzt auf der Drehachse d, konzentrisch einen Luftspalt h vom Stahlring e entfernt, ein permanenter, beispielsweise Ringmagnet i. Dreht sich die Achse, dann wird jenerFigures 1, 2 and 3 show two exemplary embodiments of the subject matter of the invention recognize. The contact springs a are isolated on the stator of the generator b, the mating contacts c isolated on one, the axis d of the generator concentrically surrounding hardened steel ring e attached. This ring can either be rotated at f stored in the stator or carried, for example, by balls g, which, as in roller bearings, rotate on the generator axis. in the The case of the first mentioned sits on the axis of rotation d, concentrically an air gap h away from the steel ring e, a permanent one, for example Ring magnet i. If the axis rotates, then it becomes that
Stahlring entweder durch die Rollreibung der Kugeln oder durch die wechselnde Magnetisierung des Stahlringes (Kysterese-Effekt), jeweils bis zu einem der Anschläge j oder k mitgenommen, ohne den weiteren Lauf der Achse zu behindern. Auf diese Weise geraten die Kontaktfedern a mit den Gegenkontakten c zu sinngemäßer Berührung (vgl. Abb. k u. 5).Steel ring either by the rolling friction of the balls or by the changing magnetization of the steel ring (cysteresis effect), each carried up to one of the stops j or k without hindering the further movement of the axis. In this way, the contact springs a come into analogous contact with the mating contacts c (see Fig. K and 5).
