Abstract

An offline algorithm for induction machine parameter determination from power and torque measurements over several torque-slip curves is presented. Based on a parameter sensitivity function, the algorithm fits the measured data of torque, stator voltage amplitude and power factor to the parameters of an equivalent circuit of the induction machine which takes main inductance saturation, iron losses and skin effect of the rotor into account. The approach is experimentally verified on test bench measurement data.
