Description
Elektromotor mit Kurzschlußläufer und po'lums ehalt barer Wicklung für den Antrieb von Zuckerzentrifugen.Electric motor with squirrel cage and po'lums sustainable Winding for driving sugar centrifuges.
Die Neuerung bezieht sich auf einen Elektromotor mit Kurzschlußläufer und polumschaltbarer Wicklung für den Antrieb von Zuckerzentrifugen. Für die Ausräumperiode des Zentrifugenbetriebes wird eine sehr niedrige Drehzahl von etwa 50 Umdrehungen pro Minute geforderte Die Unterbringung einer entsprechend hochpoligen Drehstromwicklung im Ständer des Motors würde große Schwierigkeiten bereiten, wenn nicht überhaupt unmöglich sein. Außerdem würde eine solche zusätzliche Wicklung den Motor erheblich verteuern. >The innovation relates to an electric motor with a squirrel cage and pole-changing winding for driving sugar centrifuges. For the clearing period of the centrifuge operation a very low speed of about 50 revolutions per minute required The motor stator would be very difficult, if not impossible at all. In addition, such an additional winding would be required make the engine considerably more expensive. >
Durch die Neuerung werden diese Schwierigkeiten beseitigt. Neuerungsgemäß ist die höherpolige V/icklung des Motors''als Zweiphasenwicklung ausgeführt und an das symmetrische Drehphasennetz angeschlossen. Zweckmäßig ist dabei die eine Ständerwicklung zwischen zwei Phasen und die andere, um 90° gegen die erste 7/icklung versetzte Ständerwicklung zwischen die dritte Phase des Netzes und den Nulleiter angeschlossen. The innovation eliminates these difficulties. According to the innovation the higher-pole winding of the motor is designed as a two-phase winding and connected to the symmetrical rotary-phase network. It is useful to have one stator winding between two phases and the other stator winding offset by 90 ° from the first winding connected between the third phase of the network and the neutral conductor.

Durch die besondere Ausbildung der höherpoligen V/icklung kann die bei Zuckerzentrifugen gewünscht niedrige Ausräumdrehzahl auf einfache Weise, erreicht werden. Für' die Zweiphasenwicklung wird außerdem nur 2/3 der Nutenzahl einer-gleichartigen Drehstromwicklung benötigt.Due to the special design of the higher-pole winding, the with sugar centrifuges desired low clearing speed to simple Way to be achieved. For 'the two-phase winding is also only 2/3 the number of slots in a three-phase winding of the same type is required.
