Identification of Induction Motor Parameters from Free Acceleration and Deceleration Tests

In this paper, a new step-by-step approach to identify the parameters of an induction machine combining free acceleration and deceleration transient data is presented. The measurement of the stator line voltages and currents is required only. The free acceleration torque characteristic is used in order to identify the inertia and to avoid the influence of the harmonic fields effect on the identification accuracy. The rotor resistance is identified from both free acceleration and deceleration transients data, and in that way the skin effect factor is determined. The identification results are compared with the motor parameters obtained by performing locked-rotor and no-load tests.
