Abstract

The invention relates to a method for the rotary-encoder-free, field-oriented control of the rotational speed (n) of an asynchronous machine (14), which is operated by means of a voltage source that outputs a graduated voltage (u), comprising the following steps: detecting a stator voltage (u) of a stator of the asynchronous machine (14), detecting a stator current (i) of the stator, simulating at least one field-oriented quantity (u; u; φ; ω; ω; n; i) of the asynchronous machine (14) on the basis of the detected stator voltage (u) and the detected stator current (i), producing a field-oriented target stator voltage (u) on the basis of the at least one simulated field-oriented quantity (u; u; φ; ω; ω; n; i) and the detected stator voltage (u), and feeding a target stator voltage (u) to the voltage source on the basis of the produced field-oriented target stator voltage (u) in order to control the rotational speed (n) of the asynchronous machine (14).
