摘要：
Thermal analysis is an important step in designing induction motors. Its principles require the calculation of induced currents In the rotors and obviously this phenomenon is connected to heating. Currents circulating in the stator coil also heats the machine. In this work, in order to evaluate the thermal behavior of the machine, a weak coupled modeling between electrical and thermal phenomena, is proposed taking into account the transient states. Also, in this work we introduce a new approach to take into account the airgap zone for thermal analysis. Experimental results are presented and compared with calculations.
