PATENTAMT.PATENT OFFICE.
Es sind bereits selbsterregende, kompoundierte Synchronwechselstromerzeuger bekannt, bei welchen die der Maschinenspannung proportionale Komponente des dem Feldmagneten über einen Kommutator zugeführten Erregerstromes einer auf dem Anker angeordneten Hilfswicklung entnommen wird, welche die Stelle eines Spannungstransformators vertritt. Fig. ι der Zeichnung zeigtSelf-exciting, compounded synchronous alternators are already known, in which the machine voltage proportional component of the field magnet An excitation current supplied via a commutator is arranged on the armature Auxiliary winding is removed, which takes the place of a voltage transformer. Fig. Ι of the drawing shows
ίο schematisch eine derartige zweipolige Dreiphasenmaschine, α ist die Ankerwicklung, beispielsweise eine Grammesche Ringwicklung, α' die entsprechend der Phasenzahl dreiphasige Hilfswicklung, f die Feldspulen, c die Kommutatorsegmente, b die Bürsten, welche von der Hilfswicklung gespeist werden. In Reihe mit dieser liegen die Widerstände r, an welche die Sekundärwicklungen der Stromtransformatoren t parallel angeschlossen sind, und die Widerstände r', welche zur Spannungsreglung dienen.ίο schematically such a two-pole three-phase machine, α is the armature winding, for example a Gramme ring winding, α ' the auxiliary winding three-phase according to the number of phases, f the field coils, c the commutator segments, b the brushes, which are fed by the auxiliary winding. In series with this are the resistors r, to which the secondary windings of the current transformers t are connected in parallel, and the resistors r ', which are used for voltage regulation.
Gemäß der Erfindung wird die Hilfswicklung aus leitenden Bändern gebildet, welche zwischen den Spulen der Hauptwicklung undAccording to the invention, the auxiliary winding is formed from conductive strips, which between the coils of the main winding and
den Verschlußkeilen k für die Änkernuten angeordnet werden, wie Fig. 2 zeigt. Durch diese besondere Lage der Hilfswicklung im äußersten Teil der Ankernuten, dicht unter den Verschlußkeilen, wird ihre Selbstinduktion vermindert, da der magnetische Widerstand des Streufeldes größer ausfällt als bei anderer Lage; dies ist für die funkenlose Kommutierung von Wichtigkeit. Die Keile k sind vorteilhaft an der Innenseite genutet, um die Hilfswicklung aufzunehmen. Hierdurch wird die Hilfswicklung in ihrer Lage sicher festgehalten und gleichzeitig eine Vergrößerung der Ankerabmessungen zum Zwecke der Unterbringung der Hilfswicklung vermieden. Die Bänder werden in so viel Nuten angeordnet, als erforderlich ist, um die gewünschte Spannung zu erhalten, und werden untereinander nach irgend einer der bekannten Wicklungsarten verbunden.be arranged for the Änkernuten as Fig. 2 shows the closure wedges k. This special position of the auxiliary winding in the outermost part of the armature slots, just below the locking wedges, reduces its self-induction, since the magnetic resistance of the stray field is greater than in another position; this is important for sparkless commutation. The wedges k are advantageously grooved on the inside to accommodate the auxiliary winding. As a result, the auxiliary winding is securely held in its position and, at the same time, an increase in the armature dimensions for the purpose of accommodating the auxiliary winding is avoided. The ribbons are placed in as many grooves as is necessary to obtain the desired tension and are connected to one another by any of the known types of winding.
