Temperature Rise Estimation of Totally-Enclosed Traction Motor Considering Under-Car-Body Train Draft Distribution

Minoru KONDO,  Junya KAWAMURA


  The application of totally enclosed type traction motors has been increasing because they are low-noise and require less maintenance than conventional self-ventilated type traction motor. It is very important to understand the under-car-body train-draft distribution to estimate the temperature rise of a totally enclosed type motor, because the airflow around the motor has significant effect on its cooling performance. In this paper, we show the measurement results of train-draft distribution and propose an appropriate method to set artificial wind around the motor in the off-site temperature rise test.
