Summary:Procedure for regulating the stator flux and torque of an asynchronous motor by vector control in an imaginary space vector coordinate system, in which procedure the absolute value (¦?s¦) of the stator flux and the torque (M) are determined in said coordinate system, and in which procedure the calculation coordinates are in such a position that the rotor flux (?r) is at least close to the real axis. In the procedure of the invention, the absolute value of the stator flux (¦?s¦) is regulated by means of the real part (usr) of the stator voltage and the torque (M) by means of the stator frequency (fs) The calculation coordinates are held in said position by adjusting the imaginary part (Usi) of the stator voltage.
