Description
Die Erfindung bezieht sich auf einen Einphasenmotor mit Hilfsphase und ständig angeschlossenem Kondensator sowie mit einem kontaktlosen Anlaßkreis, der ein Element veränderlicher, bei zunehmender Steuerspannung abnehmender Impedanz enthält, das parallel zu wenigstens einem Teil der Hilfsphase geschaltet ist.The invention relates to a single-phase motor with an auxiliary phase and a permanently connected capacitor as well as a contactless starting circuit, the one element of variable impedance that decreases with increasing control voltage contains, which is connected in parallel to at least part of the auxiliary phase.
Es ist bereits bekannt, mit dem Kondensator der Hilfsphase eine geeignete Drosselspule in Reihe zu schalten, gegebenenfalls in Parallelschaltung mit einem Kondensator. Eine solche Ausbildung ist jedoch sehr sperrig.It is already known to use a suitable capacitor for the auxiliary phase To connect the choke coil in series, if necessary in parallel with one Capacitor. However, such training is very bulky.
Bei einer anderen bekannten Einrichtung zur Steuerung von Einphasenmotoren mit Hilfsphasenwicklung und Anlaufkondensator wird die kapazitive Wirkung des Anlaufkondensators durch temperaturabhängige Widerstände unter dem Einfluß des Hilfsphasenstromes selbsttätig vermindert. Diese Lösung führt bei Motoren in Abhängigkeit von der Umgebungstemperatur ihrer Einsatzorte zu unterschiedlichen Hilfsphasenströmen.In another known device for controlling single-phase motors with auxiliary phase winding and starting capacitor, the capacitive effect of the starting capacitor automatically through temperature-dependent resistors under the influence of the auxiliary phase current reduced. This solution leads to motors depending on the ambient temperature their locations of use to different auxiliary phase flows.
Nach einem weiteren bekannten Vorschlag erhält man eine Erhöhung des Wirkungsgrades des Anlaufdrehmoments von Einphasenmotoren mit einer induktiven und einer kapazitätsbehafteten Wicklung dadurch, daß in Verbindung mit der kapazitätsbehafteten Wicklung eine magnetische Drosselspule vorgesehen ist, die je nach der größeren oder geringeren Sättigung ihres Magnetkreises, die ihrerseits eine Funktion der Drehzahl des Motors ist, die Spannungsänderungen an der kapazitätsbehafteten Wicklung oder am Kondensator steuert. Der Nachteil dieser Lösung ist insbesondere der, daß der Motor nicht mit normal gestanzten Blechen auskommt, sondern spezielle Bleche erfordert.According to another known proposal, an increase in the Efficiency of the starting torque of single-phase motors with an inductive and a capacitive winding in that in connection with the capacitive Winding a magnetic choke coil is provided, depending on the larger or lower saturation of their magnetic circuit, which in turn is a function of the The speed of the motor is the voltage changes on the capacitive winding or controls on the capacitor. The disadvantage of this solution is in particular that the engine does not get by with normal stamped sheet metal, but special sheet metal requires.
Alle diese bekannten relaislosen Steuervorrichtungen haben im ganzen Spannungsbereich ansprechende Vorrichtungen und vermindern deshalb schon bei geringeren Anlaufdrehzahlen das Drehmoment des Motors.All of these known relayless control devices have on the whole Devices responding to the voltage range and therefore reduce them even with lower ones Starting speeds the torque of the motor.
Ziel der Erfindung ist die Schaffung eines Einphasenmotors der angegebenen Art, bei dem insbesondere bei kleinen Drehzahlen während des Anlaufs das Drehmoment so hoch gehalten werden kann, wie es beim gewählten Kapazitätswert maximal möglich ist, und bei dem erst von einer bestimmten Drehzahl ab der Hilfsphasenstrom progressiv abfällt.The aim of the invention is to provide a single phase motor of the type indicated Type in which the torque during start-up, especially at low speeds can be kept as high as possible with the selected capacity value is, and in which only from a certain speed onwards the auxiliary phase current is progressive falls off.
Dies wird nach der Erfindung bei dem eingangs geschilderten Motor dadurch erreicht, daß das Element mit veränderlicher Impedanz eine Anordnung von zwei gegensinnig in Reihe geschalteten Zenerdioden ist.According to the invention, this is the case with the engine described above achieved in that the variable impedance element has an array of two zener diodes connected in series in opposite directions.
Die Vorteile des erfindungsgemäßen Motors sind neben der angegebenen günstigen Gestaltung des Drehmoments und des Stromverlaufs in der Hilfsphase noch darin zu sehen, daß die Anordnung einfach und raumsparend ist und für häufigen Einschaltbetrieb geeignet ist.The advantages of the engine according to the invention are in addition to those indicated favorable design of the torque and the current flow in the auxiliary phase it can be seen that the arrangement is simple and space-saving and for frequent switch-on operation suitable is.
Die Erfindung ist nachstehend unter Bezugnahme auf die Zeichnung beispielshalber erläutert, in welcher die F i g.1 bis 3 drei verschiedene Ausführungen zeigen.The invention is described below by way of example with reference to the drawing explained, in which the F i g.1 to 3 show three different versions.
Der Einphasenmotor (F i g. 1, 2 und 3) hat eine Hilfsphase 1 und einen ständig angeschlossenen Kondensator 2. Gemäß F i g.1 und 2 besteht die Hauptphase des Motors aus einer einzigen Wicklung 3. Gemäß F i g. 3 besteht die Hauptphase dagegen aus zwei Wicklungen 4 und 5. Gemäß F i g. 1 sind zwei gegensinnig, d. h. mit entgegengesetzten Polaritäten in Reihe geschaltete Zenerdioden 6 und 7 parallel zu einem Teil der Hilfsphase 1 geschaltet. Diese Zenerdioden haben die Aufgabe, den Strom in der Hilfsphase 1 zu begrenzen, wenn die Spannung an ihren Klemmen bei höheren Drehzahlen des Motors zunimmt.The single-phase motor (FIGS. 1, 2 and 3) has an auxiliary phase 1 and a permanently connected capacitor 2. According to FIGS. 1 and 2, the main phase of the motor consists of a single winding 3. According to FIG. 3, on the other hand, the main phase consists of two windings 4 and 5. According to FIG. 1, two zener diodes 6 and 7 connected in series in opposite directions, ie with opposite polarities, are connected in parallel with part of the auxiliary phase 1. These zener diodes have the task of limiting the current in auxiliary phase 1 when the voltage at their terminals increases at higher engine speeds.
Es ist auch möglich, die Zenerdioden 6,7 zum Kondensator des Hilfsphasenkreises parallel zu schalten (F i g. 2). Gemäß F i g. 3 sind die Zenerdioden 6 und 7 zur gesamten Hilfsphasenwicklung 1 parallel geschaltet, wobei die Hilfsphasenwicklung 1 mit dem Kondensator 2 der einen Wicklung 5 der aus den Teilwicklungen 4 und 5 bestehenden Hauptphase parallel geschaltet ist. Diese sehr vorteilhafte Schaltungsart ist für einen Motor von 110/220 V gedacht.It is also possible to connect the Zener diodes 6, 7 in parallel to the capacitor of the auxiliary phase circuit (FIG. 2). According to FIG. 3, the Zener diodes 6 and 7 are connected in parallel to the entire auxiliary phase winding 1, the auxiliary phase winding 1 being connected in parallel with the capacitor 2 of one winding 5 of the main phase consisting of the partial windings 4 and 5. This very advantageous type of circuit is intended for a 110/220 V motor.
