The subject of this research is to describe in more detail the procedure of simulation verification of rotor position acquisition using the method of injecting a high-frequency continuous signal at a frequency of the supply signal up to 5Hz, i.e. in the range of zero and low speeds. For injecting a continuous signal to monitor the asymmetry of rotary electrical machines, the implementation of these methods is generally simpler than injecting discrete signals, but the process of obtaining information about the position of the monitored asymmetries in processing signal responses is more complex. To verify this method as realistically as possible, it is necessary to design a mathematical model of the motor, which also includes asymmetries caused by the influence of the rotor grooves and asymmetry created by the saturation of the magnetic core. These asymmetries in asynchronous motors quite radically affect the instantaneous value of the stator inductance LS. Since the asymmetries caused by the saturation of the magnetic circuit caused the distortion of the measured signal, they had to be identified and subsequently eliminated. The LMDEM metode was used as the elimination method to suppress these asymmetries. Subsequently, the signal, which contained only information about the position of the asymmetry caused by the rotor grooves, was converted to the rotor position by means of the arctan function and subsequent multiplication by the number of rotor teeth.
