THERMAL PROCESSES OF ASYNCHRONOUS FREQUENCY-CONTROLLED MOTOR TAKING INTO ACCOUNT TRACTION LOADS
Вестник КазАТК, 2022 In the article proposes a method for estimating the thermal state of an asynchronous traction motor. A block diagram of a thermal model of an asynchronous traction motor is presented in which the stator and rotor are modeled as concentric rotating cylinders.

Modeling of asynchronous traction motor operation modes while turning locomotive wheelsets bandages [PDF]
Proceedings of the International Conference "Aviamechanical engineering and transport" (AVENT 2018), 2018 At present special machines with built-in electric dr ives, including the electric drive of rotation of the wheelset, are used for turning the wheelset bandage without moving it from the locomotive.

Stator ITSC Fault Diagnosis of EMU Asynchronous Traction Motor Based on ApFFT Time-shift Phase Difference Spectrum Correction and SVM [PDF]
Energies, 2023 EMU (electric multiple unit) traction motors are powered by converters whose output voltage increases the voltage stress borne by the insulation system, making the ITSC (inter-turn short-circuit) fault more prominent.
