    • A method and a device are described for determining an angular velocity of the rotor of a polyphase machine operated by field orientation without a transmitter, wherein control signals, a stator current model space vector and a conjugated complex reference space vector are calculated by a signal processor containing, among other things, a complete machine model and a modulator, as a function of a flux setpoint, a torque setpoint, a d.c. voltage value, measured power converter output voltage values and system parameters, with a real stator current space vector which is measured and the calculated stator current model space vector are being multiplied by the calculated conjugated complex reference space vector, and the imaginary components of the results being compared with one another, and the system deviation determined therefrom being used to adjust the angular velocity of the rotor as a system parameter in such a way that the system deviation thus determined becomes zero. In this method, the stator current model space vector and the real stator current space vector are each processed in angular position and modulus as a function of the operating point before these processed space vectors are transformed into the complex reference system. Thus, the operational dependence of the relationship between the rotational speed difference and the system is greatly reduced.
