Description

Zweiphasenstroinerzeuger für hohe Frequenz. Die Erfindung betrifft einen Hochfrequenzstromerzeuger für Zweiphasenstrom mit verhältnismäßig großen Nuten im Stator.Two-phase power generator for high frequency. The invention relates to a high-frequency generator for two-phase electricity with relatively large grooves in the stator.

Abb. i zeigt eine Seitenansicht der Verzah-. nung des Statorankers 2 und des Rotorfeldes i eines derartigen gleichpoligen Hochfrequenzstromerzeugers für Zweiphasenstrom.Fig. I shows a side view of the toothing. tion of the stator armature 2 and the rotor field i of such a homopolar high-frequency current generator for two-phase current.

Das rotierende Feld wird .aus vorstehenden Polen gebildet, deren Breite im Luftzwischenraum beispielsweise derjenigen der Zwischenräume gleich .ist, dile die Pole entgegengesetzten Zeichens darstellen. Der ruhende An4 ker 2 enthält Nuten., deren Breite derjenigen der Polvorsprünge oder Lücken des Rotors gleicht, und Stege von halb so großer Breite. Dementsprechend werden in den voneinander unabhängigen Spulen 3 und q. zwei. verschiedene zweiphasige Ströme gewonnen, deren Frequenz durch die Anzahl der Polvorsprünge des Rotors bestimmt ist, wie bei einer gewöhnlichen Gleichpolmaschine. Tatsächlich schwingt in jeder Spule der magnetische Kraftfluß zwischen den Höchst- und Mindestwerten, die durch die in den Abb. 2 und 3 veranschaulichten Stellungen gegeben sind.The rotating field is formed from protruding poles, their width in the air gap, for example, that of the gaps is equal to, dile represent the poles of opposite signs. The stationary anchor 2 contains grooves., the width of which is equal to that of the pole projections or gaps of the rotor, and webs half as wide. Accordingly, in the independent Coils 3 and q. two. different two-phase currents obtained, their frequency by the number of pole lugs of the rotor is determined, as in an ordinary one Homopolar machine. In fact, the magnetic flux oscillates in every coil between the maximum and minimum values illustrated by those illustrated in Figures 2 and 3 Positions are given.

In der drahtlosen Telegraphie wird Zweip:hasenstrom zur Speisung von Antennen verwendet, wie beispielsweise die amerikanische Patentschrift 1145239- von G i r a r d e a u und B e t h e n .o d zeigt. Die mehrphasigen Stromerzeuger haben bekanntlich den Vorteil, daß sie mit Bezug auf die Leistung eine erhöhte Ausnutzung des Raumes und einen besseren Wirkungsgrad ergeben.In wireless telegraphy, Zweip: hasenstrom is used to feed Antennas used, such as the American patent specification 1145239- von G i r a r d e a u and B e t h e n .o d shows. The multi-phase power generator are known to have the advantage that they have an increased utilization with regard to performance of the room and result in better efficiency.

Die Nutendes Stators sind in den Abb. i, 2 und 3 offen dargestellt, sie können jedoch auch geschlossen oder halb geschlossen sein.The slots of the stator are shown open in Figs. I, 2 and 3, however, they can also be closed or semi-closed.

Der Rotor wird zweckmäßig lamelliert oder mit einer den Statorflluß abschirmenden Dämpfungsvorrichtung versehen sein. Es würden sonst :bei dieser Art von Spezialmaschinen die Rotorlücken sehr beträchtlich sein müssen.The rotor is expediently laminated or with a stator flux shielding damping device be provided. Otherwise: with this species of special machines the rotor gaps must be very considerable.
