摘要：
The mathematical and physical modelling are shown to be required to investigate temperature condition of traction induction motors on locomotives. The physical model of traction and auxiliary drive of locomotive developed and constructed to investigate the thermal and electromechanical and control processes is presented. The technique and results of experimental investigation of thermal processes of heating and cooling in the 14 kW induction motor fed by frequency converter with scalar control and IR-compensation under the low values of the stator current frequency and rotor speed are presented. The rotor squirrel-cage rings of the induction motor are determined to be most stressed by overheating under the stator current frequency closed to null, the stator end winding on the side opposite to air supply becomes the most overheated unit of the induction motor under higher values of the stator current frequency.
