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.

Abstract:The air cooling systems are shown to be used to provide required temperature condition of traction induction motors on locomotives. The automatic temperature regulation system is developed for its using to solve such a task. Results of experimental investigation showed that the AO63-4 induction motor stator end winding on the side opposite to air supply is the most heated part of the induction motor. Based on the results of the research, it was used an aperiodic second-order transfer function for approximation of the thermal transient curves. The design of an induction motor control system maintaining operating mode with minimum of the stator current are considered. It is shown that the modes of minimum of the stator current and minimum of power losses are quite close to each other. The MatLab simulation results taking typical nonlinearities and iron power losses in an induction motor and conduction and commutation power losses in semiconductors of frequency converter into account are presented. It is shown that as a result of application of the suggested system the power losses reduction may be led up to 20 % relatively to classical scalar control.
