Abstract :
The paper presents a model for coupling electromagnetic and thermal phenomena in an induction motor. The thermal analysis is done using an equivalent thermal network whose losses are determined from a complex finite element analysis of the magnetic field. The electromagnetic model includes both saturation and space harmonics. To show the validity of the proposed method, a test bench is realized so predicted and measured temperatures are compared.
