JARAMILLO-MATTA, ADOLFO ANDRÉS; FRANCO-MEJIA, EDINSON  y  GUASCH-PESQUER, LUIS. INVARIANTS PARAMETER ESTIMATION FOR AN INDUCTION MOTOR. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.169, pp.88-94. ISSN 0012-7353.

This paper shows an algorithm that implements a new technique for estimating invariant parameters for the three-phase induction motor with squirrel cage rotor, for two of the most widely used models: single-cage model and double-cage model without loss on the gap. This technique starts only from the manufacturer data, and significantly improves the errors identified in other techniques. The results are compared with experimental data from a three-phase induction motor of 100 hp, and show marked differences between the behavior obtained with the single-cage model and the obtained one with the double-cage model. This difference may affect the performance of applications which include induction motors, such as control systems, analysis, simulation and emulation of electric drives, among others.

Palabras clave : Induction motors; parameters estimation; steady state.
