Identification of Induction Motor Parameters from Free Acceleration Test Measurements

This paper describes a method for estimating the parameters of an three-phase induction motor using the measurements of the stator line voltages and currents during startup transient. The identification method presented minimizes errors in the observed properties of loss functions in the least-squares sense using a Levenberg-Marquardt method. A special procedure for the initial estimates of the motor parameters is presented. The parameters obtained using the identification method are compared with ones obtained from standard tests.
