Patentansprüche:Patent claims: 1. Verfahren zum Betrieb einer drehstromgesteuerten Asynchronmaschine mit Kurzschlußläufer, wobei der Fluß der Maschine entsprechend vorgegebenen Randbedingungen optimal gewählt und konstant gehalten wird, gekennzeichnet durch einen Regelkreis, in dem der Istfluß der Asynchronmaschine, dargestellt durch einen dem Fluß proportionalen Magnetisierungsstrom-Wert ///ist mit einem vorgebbaren Sollwert für den Fluß, dargestellt durch einen dem Fluß proportionalen Magnetisierungsstrom-Wert /μ80ΐΙ verglichen wird und die Regelabweichung die Frequenz eines den Motor speisenden Wechselrichters derart ändert, daß /^ist gleich //U8011 wird, wobei in einem weiteren Regelkreis der Ständerstrom /ist entsprechend einem fest vorgegebenen Wert /so!1 geregelt ist.1. Method for operating a three-phase controlled asynchronous machine with squirrel cage rotor, whereby the flux of the machine is optimally selected and kept constant according to given boundary conditions, characterized by a control loop in which the actual flux of the asynchronous machine, represented by a magnetizing current value proportional to the flux /// is compared with a predeterminable setpoint for the flux, represented by a magnetizing current value / μ 80ΐΙ proportional to the flux, and the control deviation changes the frequency of an inverter feeding the motor in such a way that / ^ is equal to // U 8011 , with one further control loop the stator current / is regulated according to a fixed predetermined value / so! 1 is regulated. 2. Anordnung zur Durchführung des Verfahrens nach Anspruch 1, gekennzeichnet durch eine zusätzliche dünndrahtige Siänderwicklung, die über eine Drossel den dem Fluß proportionalen Magnetisierungsstrom durch einen Wert //xist nachbildet.2. Arrangement for carrying out the method according to claim 1, characterized by an additional thin-wire Siander winding which, via a throttle , simulates the magnetizing current proportional to the flux by a value // x.
