Description

Emphasenasynchronmotoren brauchen bekanntlich zum Anlaufen eine Hilfsphase, die durch irgendwelche Phasmverschiebungsmittel (Kapazität, Induktivität, Widerstand) gegenüber der Hauptphase verschoben ist. Es ist schon bekannt, 'diese Phasenverschiebungsmittel in das Motorgehäuse, z. B. in den Motorfuß, einzubauen, um an Raum zu sparen.As is known, emphasis asynchronous motors need an auxiliary phase to start up by any means of phase shifting (capacitance, inductance, resistance) the main phase is postponed. It is already known 'these phase shifting means in the motor housing, e.g. B. in the motor base to install in order to save space.

Die Erfindung besteht darin·, daß das Phasenverschiebungsmittel in dem Ölbad des von dem Motor angetriebenen- Verdichters angeordnet wird, um es zu isolieren und zu kühlen. Beim Antrieb von Kaltemaschinenverdichtern wird das im Ölbad des Verdichters liegende Phaaenverschiebungsmittel gleichzeitig gegen Angriffe des Kältemittels geschützt, so daß man es in dem kältemittelerfüllten Ver dicht ergehäuse unterbringen kann.The invention consists in that the phase shifting means placed in the oil bath of the compressor driven by the engine is used to isolate and cool it. When driving cold machine compressors the phase shifting means located in the oil bath of the compressor becomes at the same time Protected against attacks by the refrigerant, so that you can fill it in the refrigerant Compressor housing can accommodate.

Die Erfindung ist in der Zeichnung in beispielsweiser Ausführungsform dargestellt, und zwar zeigt:The invention is shown in the drawing by way of example Embodiment shown, namely shows:

Abb. ι einen senkrechten Achsenschnitt durch 'eine Kleinkältemaschine,Fig. Ι a vertical axis section through 'a small refrigeration machine,

Abb. 2 'ein Schaltungsschema des in Abb. 1 gezeigten Motors.Fig. 2 'is a circuit diagram of the one shown in Fig. 1 shown motor.

α ist ein Verdichtergehäuse, das in bekannter Weise eine gasdichte Hülle für eine aus Motor und Verdichter bestehende Kleinkälteanlage bildet. Der mit einem feststehenden Kolben b versehene Drehkolbenverdichter c ist in den Läufer d des Einphasenasynchronmotors eingebaut, dessen. Ständer mit e bezeichnet ist. Die Schaltung des Motors ist in Abb. 2 gezeigt. Die Ständeorwicklung e besteht in bekannter Weise aus einer Hauptwicklung e1, der eine Hilfswicklung ,e2 nebengeschaltet ist. In den Hilfsphasenkreis ist ein PhasenverSchiebungsmittel, z. B. ein Kondensator/, geschaltet, der in dem über dem Boden g des Verdichtergehäuses α stehenden Ölbad h des Verdichters angeordnet ist. Das Ölbad schützt das Phasenverschiebungsmittel/, das natürlich auch 'eine Drosselspule oder ein Widerstand sein kann, gegen Erhitzung, elektrische Überschläge und gegen die Angriffe des Kältemittels. α is a compressor housing which, in a known manner, forms a gas-tight envelope for a small refrigeration system consisting of a motor and a compressor. The rotary piston compressor c, which is provided with a stationary piston b , is built into the rotor d of the single-phase asynchronous motor. Stand is denoted by e. The circuit of the motor is shown in Fig. 2. The stator winding e consists in a known manner of a main winding e 1 , to which an auxiliary winding , e 2 is connected. A phase shifting means, e.g. B. a capacitor /, connected, which is arranged in the oil bath h of the compressor standing above the bottom g of the compressor housing α. The oil bath protects the phase shifting means /, which can of course also be a choke coil or a resistor, against heating, electrical flashovers and the attacks of the refrigerant.
