Description
Elektrische Maschine mit außerhalb und innerhalb eines Ringankers angeordneten, unter Umständen gegeneinander versetzten Feldmagnetpolen. Die Erfindung bezieht sich auf elektrische Maschinen mit außerhalb und innerhalb eines Ringankers liegenden Magnetpolen, die einander gegenüberstehen oder versetzt zueinander angeordnet sein können. Der Ankerkern dieser Maschine besteht aus zwei konzentri-_sehen, durch eine ummagnetisierbare Schicht voneinander getrennten Eisenzylindern, in denen durch Einwirkung der den Zylindern gegenüberstehenden Magnetpole, falls sie eine unterschiedliche Stärke aufweisen, eine verschieden starke magnetische Kraft erzielt werden kann, so daß an den Ankerklemmen sich eine verschieden hohe Klemmspannung erhalten läßt. Der in der Maschine auftretende Spannungsverlust, welcher infolge starker Stromentnahme entsteht, läßt sich z. B. einfach durch Änderung der magnetischen Kraft des einen Zylinders erreichen.Electric machine with outside and inside a ring armature arranged, possibly mutually offset field magnetic poles. The invention refers to electrical machines with outside and inside a ring armature lying magnetic poles that face each other or are arranged offset to each other could be. The armature core of this machine consists of two concentric-see through a magnetizable layer separated from each other iron cylinders, in which by Effect of the magnetic poles opposite the cylinders, if they are different Have strength, a different strength magnetic force can be achieved, so that different levels of clamping voltage can be obtained at the anchor terminals. The voltage loss that occurs in the machine, which is due to the high current consumption arises, can be z. B. simply by changing the magnetic force of one Reach the cylinder.
Abb. i ist ein Schnitt durch eine derartige Maschine, Abb.2 ein Längsmittelschnitt nach der Linie A-B in Abb. 2, Abb. 3 eine Vorderansicht des Ankers und zeigt dessen Befestigung, Abb. q. ein Schnitt nach der Linie C-D der Abb. 3, Abb. 5 ein nach der Linie E-F der Abb. 3 geführter Schnitt.Fig. I is a section through such a machine, Fig. 2 is a longitudinal center section according to the line A-B in Fig. 2, Fig. 3 is a front view of the anchor and shows it Attachment, Fig.q. a section along the line C-D of Fig. 3, Fig. 5 a after the line E-F of Fig. 3 guided section.
Die Maschine weist einen Anker i auf, der aus zwei konzentrischen, durch eine unmagiietisierbare Schicht 5 voneinander getrennten Eisenzylindern besteht und eine bekannte Ringwicklung 2 besitzt. Die unmagnetisierbare Schicht 5 kann an ihrem vorstehenden Rand durch einen Ankerträger 6 mit der Welle 3 verbunden werden (Abb. 3 u. 4). Damit sich der Zylinder 5 zwischen den beiden Eisenzylindern leichter befestigen läßt, weist er Längsschlitze 7 auf, so daß die einzelnen Segmente federn und ein festes Anlegen an die Zylinderoberfläche der Eisenzylinder ermöglichen.The machine has an armature i, which consists of two concentric, consists of iron cylinders separated from one another by an unmagiietisable layer 5 and a known ring winding 2 has. The non-magnetizable layer 5 can their protruding edge are connected to the shaft 3 by an armature support 6 (Fig. 3 and 4). So that the cylinder 5 between the two iron cylinders is easier can be attached, it has longitudinal slots 7 so that the individual segments spring and allow a firm application to the cylinder surface of the iron cylinder.
Die Feldmagnete q. liegen sowohl innerhalb als auch außerhalb des Ankers i, und zwar können ihre Pole einander gegenüberstehen oder auch versetzt zueinander angeordnet sein.The field magnets q. lie both inside and outside the Anchor i, namely their poles can face each other or offset be arranged to each other.
Es entstehen also mehrere Magnetfelder, die in den Ankerwindungen bei der Drehung des Ankers i Ströme erzeugen. Bei entsprechender Polarität der Magnetpole unterstützen sich die in den inneren und äußeren Spulenseiten erzeugten Ströme in ihrer Wirkung.So there are several magnetic fields in the armature windings when the armature rotates i generate currents. With the corresponding polarity of the magnetic poles the currents generated in the inner and outer coil sides support each other their effect.
Dadurch, daß beide den Ankerkern i bildende konzentrische Eisenzylinder durch eine unmagnetisierbare Zwischenlage voneinander getrennt sind, ist es möglich, die magnetische Kraft in den beiden Zylindern verschieden stark zu machen und dadurch den bei wechselnder Stromentnahme auftretenden Spannungsverlust auszugleichen.Because both concentric iron cylinders forming the armature core i are separated from each other by a non-magnetizable intermediate layer, it is possible to to make the magnetic force in the two cylinders differently strong and thereby to compensate for the voltage loss that occurs when the current consumption changes.
