Regelung eines Asynchron-Motors

1974
Aus der Darstellung der Betriebseigenschaften des Asynchronmotors geht hervor, das eine Anwendung als Regelantrieb mit weitem Drehzahlbereich die Verfugbarkeit eines ruhenden Drehstromerzeugers veranderlicher Frequenz mit einer genugenden Leistungsfahigkeit und hohem Wirkungsgrad voraussetzt.

Instability Regions of Variable Frequency Supplied Asynchronous Motors

IFAC Proceedings Volumes, 1983
Abstract The paper tries to answer the question if and when unstable operations occur in practice in asynchronous motors supplied by variable frequency voltages. It is found and shown that unstable operating ranges are in practice greatly reduced in comparison with theoretical evaluations, obtained by simply considering the independent variation of ...

Parasitic Torques of Saturised Asynchronous Motors

IEEE Transactions on Power Apparatus and Systems, 1972
The paper deals with the analysis of field harmonics in an asynchronous machine. It is proved that with increasing saturation of the magnetic circuit, the influence of the higher space harmonics on the field form is reduced. This causes reduction of the parasitic torques.

A COMPARISON BETWEEN OPERATING CONDITIONS OF INVERTERFED ASYNCHRONOUS MOTORS

IFAC Proceedings Volumes, 1977
Publisher Summary The performances of the inverter-fed asynchronous motors have been widely investigated in the past few years. The machines can be obviously operated according to different control techniques and obtain operating conditions quite different as compared with the same machines supplied with constant frequency and voltage.
