CALCULATION OF ARMATURE TEMPERATURE RISE VALUES OF TRACTION MOTOR UNDER TRAIN OPERATING CONDITIONS

Load current for traction motors is up to 1.5 times the rated amperage over a very wide speed range, very severe operating conditions as compared with standard electric motors. Because armature construction of traction motors is complicated, localized heating can produce insulation damage. This study was to produce a method of calculating temperature rise of motors under varying operating conditions for the benefit of motor and rolling stock designers.
