The selected simulation results of the angular velocity estimator, whose operation algorithm has been elaborated basing on the inductance frequency characteristic of the considered induction motor (IM), have been presented in the paper. The simulations have been conducted at specified operating frequencies of the scalar-controlled induction motor drive with a modulator employing the space vector pulse width modulation technique. This allowed for the indication of the influence of the IM current distortion on the accuracy of the IM angular velocity estimation process and thereby the efficiency of the considered IM drive. The impact of the estimator input signals filtering on the level of angular velocity estimation and tracking errors has been also investigated in the paper. The analysis has been conducted for the mathematical model of the four-pole induction motor of Sg 132S-4 type with a solid rotor manufactured from the magnetic material S235JR.
