Zusatz zum Patente 165053 vom 25. Mai 1904.Addendum to patent 165053 from May 25, 1904.

Patentiert im Deutschen Reiche vom 12. Dezember 1907 ab. Längste Dauer: 24. Mai 1919.Patented in the German Empire on December 12, 1907. Longest duration: May 24, 1919.

Im D. R. P. 165053 ist ein kompensierter Einphasenmotor beschrieben, welcher zum Zweck des Anlassens und der Tourenregulierung eine regelbare Querwicklung besitzt. Die Tourenzahl, bei welcher der Motor arbeitet, ist abhängig von dem Verhältnis der Windungszahlen der Querwicklung und des Rotors.In the D. R. P. 165053 a compensated single-phase motor is described, which for The purpose of starting and regulating the tour has an adjustable transverse winding. The number of revolutions at which the engine works depends on the ratio of the Number of turns of the transverse winding and the rotor.

Die in diesem Patent und in den Zusatzpatenten 165054 und 165055 beschriebenen Mittel zur Einstellung der Umdrehungszahl beruhen also alle darauf, daß das Verhältnis der Windungszahlen von Querwicklung und Rotorwicklung verändert wird durch Veränderung der Windungszahl der Querwicklung. Those described in this patent and additional patents 165054 and 165055 Means for setting the number of revolutions are therefore all based on the fact that the ratio the number of turns of transverse winding and rotor winding is changed by changing the number of turns of the transverse winding.

Von diesen Mitteln gestattet der Induktionsregulator, dessen Anwendung im Zusatzpatent 165054 gezeigt ist, eine allmähliche Abstufung der Windungszahlen; bei allen anderen Mitteln, z. B. der Unterteilung der Querwicklung in mehrere Teile, die nach Bedarf eingeschaltet werden, oder bei der Einschaltung eines regelbaren Transformators vor die Querwicklung ist die Abstufung mehr oder weniger sprungweise, und eine feine Abstufung erfordert einen großen Kontaktapparat und viele Zuleitungen.Of these means, the induction regulator allows its use in the additional patent 165054 is shown a gradual gradation of the number of turns; with all other means, z. B. the subdivision of the transverse winding into several parts that are switched on as required or when switching on a controllable transformer in front of the transverse winding the gradation is more or less leaps and bounds, and a fine gradation is required a large contact apparatus and many supply lines.

In Fällen, wo eine feine Abstufung gewünscht wird, der Induktionsregulator aber nicht angebracht ist, läßt sich dies auch bei nur wenigen Stufen der Querwicklung durch Verschiebung der Bürsten erreichen.In cases where a fine gradation is desired, the induction regulator does is not appropriate, this can be done with only a few steps of transverse winding Achieve displacement of the brushes.

Verwendet man die Bürstenanordnung nach Patent 163295 mit drei um 120⁰ gegeneinander versetzten Bürsten, so arbeitet dieser Motor, wie im Zusatzpatent 168496 hervorgehoben ist, auch gut, wenn die kurzgeschlossenen Arbeitsbürsten um einen Winkel gegeneinander verschoben sind, der von 120⁰ abweicht und zwischen 90 ° und i8o° liegen kann.To use the brush assembly according to Patent 163,295 with three 120 ⁰ staggered brushes, so, this engine, as highlighted in the patent of addition 168 496 works well when the shorted working brushes are moved at an angle to one another which differs from 120 ⁰ and between 90 ° and i8o °.

Verändert man den Winkel zwischen den kurzgeschlossenen Bürsten, so verändert man die Windungszahl der Rotorstromkreise, und bei einer bestimmten Windungszahl der Querwicklung also auch das Verhältnis der Windungszahlen der Querwicklung und Rotorwicklung und damit die Tourenzahl.If you change the angle between the short-circuited brushes, you change the number of turns of the rotor circuits, and with a certain number of turns of the transverse winding thus also the ratio of the number of turns of the transverse winding and rotor winding and thus the number of turns.

Bringt man daher an der Bürstenbrücke eine Vorrichtung an, um die Bürsten allmählich so zu verschieben, daß der Winkel zwischen den kurzgeschlossenen Bürsten geändert wird, so braucht die Querwicklung nur grob unterteilt zu sein, und für jede Stufe der Querwicklung läßt sich die Tourenzahl durch obige Verschiebung der Bürsten in feineren Zwischenstufen allmählich verändern. Therefore, if you attach a device to the brush bridge, the brushes gradually move so that the angle between the shorted brushes changed the transverse winding need only be roughly divided, and for each In the transverse winding stage, the number of revolutions can be determined by shifting the brushes above change gradually in finer intermediate stages.

Für die Bürstenanordnung nach dem Zusatzpatent 167305 mit verdoppelter Bürstenzahl gilt das gleiche.For the brush arrangement according to the additional patent 167305 with doubled number of brushes the same applies.

Claims

The route regulation procedure described here differs in principle from the z. B. in repulsion engines applied method of route regulation by Brush shift. Because with the latter, the magnetic axis of the rotor is opposite shifted to the stator or, which means the same thing, the ratio of the stator turns, those in the axis of the shorted

ίο Brush and magnetize perpendicular to it, changed.

Here, however, the magnetic axes of neither the stator nor the rotor are changed, the ratio of the number of turns of the stator in the axis of the short-circuited Brushing and perpendicular to it remains unchanged for each step of transverse winding, it becomes only changed the ratio of the number of turns of the rotor winding and transverse winding; the method can therefore only be used for motors with transverse winding.

Fig. Ι and 2 show the application of this method. Fig. 1 shows a main circuit motor with the stator main winding S and the controllable transverse winding QW. K is the commutator with the three brushes B ₁ , B ₂ , B _& , of which -B ₁ and B _{2 are} short-circuited. These two brushes B ₁ and B ₂ are adjustable, both brushes are adjusted at the same time, either approached or removed from one another, so that the short-circuited working circuit and the excitation circuit of the rotor lying perpendicular to it always keep the same magnetic axis.

Fig. 2 is a shunt motor, 'the relationships are the same as in Fig. 1, only here the brush arrangement is made so that when adjusting the four brushes B ₁ , B ₃ and B _t , B _6, the number of turns of the working circuit through the special short circuit B ₂ -B ^ remains unchanged when the number of turns of the excitation circuit is changed.

If such special working brushes are used, the change in the number of turns of the excitation circuit can also be achieved in motors with simple excitation brushes instead of pairs of brushes. So you could omit the brushes B ₁ and B ₆ in Fig. 2 and adjust the brushes so that you move the brushes B ₁ and B _& , which now only carry the excitation current, by the same angle from the axis of the transverse winding.

Patent-A ν claim:

Method for route control of compensated single-phase motors with transverse winding according to patent 165053, characterized in that the excitation current leading brushes are adjusted in their position to the axis of the transverse winding without affecting the axis of magnetization the rotor winding is shifted in its position, for the purpose of changing the ratio of the number of turns of the Rotor and the transverse winding.
