Abstract: The estimation methodology of induction motor (IM) angular velocity and rotor flux space vector is presented in the paper. The estimation algorithms are based on the knowledge of the measured IM Inductance Frequency Characteristic (IM-IFCh) and its approximation resulting from the machine secondary multi-loop equivalent circuit (SML-EC). The waveforms of motor speed an rotor flux space vector reconstructed with the use of the proposed estimation algorithms are compared with the waveforms of adequate quantities determined by the simulation of the mathematical model of the IM fed by a Voltage Source Inverter employing the Pulse Width Modulation technique (PWM-VSI).
