The paper discusses the transient heating process and the response of a small-powered induction motor to a permanent constant rated load and single-phasing mode with stalled rotor all under a standard electrical supply system (400 V, 50 Hz) for cold and warm initial conditions and a constant ambient temperature. 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 heat capacity C calculation are composed in MATLAB-SIMULINK. The variable temperature rise time and sensitivity factors are calculated using experimental data. Simulation results demonstrate adequacy of developed model to experimental data. Analyses show that the maximum difference of simulation and experimental results is ±2 °C.
