Experimental investigations were performed on a 1.1 kW totally enclosed, fan-cooled three-phase induction motor ABB M2AA90S-4. The transient temperatures are measured at 9 separate points on the stator windings and in 2 points of the motor casing using thermocouples and loggers for data processing and archiving. The test results show that heating of induction motor stator windings is a non-stationary process with variable temperature rise time and sensitivity factors. For stator winding non-stationary heating simulation an adaptive self-tuning model with open access transfer function module and modules of temperature dependent winding resistance R, heat dissipation H and hea...
