Induction motor electromechanical quantities estimation based on the inductance frequency characteristic — Simulation studies

The estimation methodology of electromechanical quantities of an induction motor has been presented in the paper. The investigated estimation algorithms are based on the motor inductance frequency characteristic and the machine secondary multi-loop equivalent circuit, reproducing this characteristic in the analyzed frequency range. The conducted simulation studies indicate the possibility of using the proposed algorithms in an estimation process of considered electromechanical quantities of an induction motor.
