In this paper, an effective on-line method for induction motor parameter identification, especially rotor parameters, based on the H-G diagram is presented for motor thermal monitoring purpose. The H-G diagram is established from the analysis of the induction motor measurement of active and reactive power consumption for each operating point. Computer simulations and experimental tests, carried out for a 4-kW four-pole squirrel cage induction motor, provide an encouraging validation of the proposed thermal monitoring technique. The process should be refined for a possible industrial application.
