In this paper is intended to study a three phase induction motor for railway applications. The steady state equivalent circuit is used to include and quantify all motor losses in the power balance.

The use of the proposed equivalent circuit, which allows a reliable assessment of the loss distribution and performance of this motor at different operating points, so comes as a particularly interesting tool to evaluate efficiency improvements, either in the motor design or in the materials selection.

Currently motor performance evaluation in railway applications is especially interesting, where the energy consumption has a significant economic and environmental impact.
