Abstract

The article presents methods for evaluating the calculation of the thermal state of the asynchronous drive of an electric locomotive engine, taking into account the complex operating modes of the asynchronous drive (recovery), Assessing the thermal state of traction asynchronous electric motors, taking into account power losses, will increase the energy performance of the electric drive and will continuously monitor the thermal state of the asynchronous traction motor, as well as timely prevent possible emergencies.
