Caracterización de motores de inducción para tracción ferroviaria a partir del circuito equivalente, incluyendo todas las pérdidas del motor

Resumen

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.
