Annotation: The calculation results of the traction induction motor thermal field are presented by two methods: graphical method in the environment ELCAD and using thermal mathematical model implemented in the environment Matlab. Traction electric motor temperature fields are constructed at nominal operating conditions and at increased value of stator current. The registration necessity of temperature not only grooving, but also winding front parts of the electric motor is shown. The calculation results showed the necessity of using motor temperature monitoring during operation.
