THERMAL MODELING FOR AN INDUCTION-MOTOR

The authors of this paper intend to achieve the study of the thermal behaviour in permanent rate of an asynchronous motor with a wounded rotor of a rated power of 4 kW. 66 thermocouples have been settled in the stator at different places like the centers and the bottoms of the windings or the middle of the yoke. A design has been realized thanks to the magnetostatic modulus of the computation software with the finite elements method Flux2d converted in a resolution tool of the heat equation. Another originality of this study is to introduce areas including a contact thermal resistance phenomenon in some places of the motor to characterize the motor thermophysical parameters and to obtain the experimentation-calculation convergence.
