Thermal modeling of a linear induction motor used to drive a power supply system for an electric locomotive

In this article a thermal modeling is developed for a double sided linear induction motor which is used to drive a power supply system for an electric locomotive. Two cases were considered for the linear motor, with full plate armature and with sectioned plate armature. The thermal model has been obtained with Pro/Engineering software package and the mesh of the 3D thermal model has been done using tetrahedron solid elements types. Experimental validation of the model has been realized too. Errors between the simulations and the experimental data (between 1% and 4%) show that the proposed model can be used for accurate precision of the heat distribution on the linear motor.
