The failure occurrences of DC traction motors used at Seoul metropolitan subway lines are investigated over 9 years from 1996 to 2004 by analysing the replacement records of the motor assemblies during maintenance works.
Based on the nine year's failure data of DC traction motors collected from maintenance field, the reliability index of MTBF(Mean Time Between Failures) has been calculated. It amounts to that the MTBF of the stator extends to 19 years while that of the rotators extends to 17 years. The MTBF values and reliability evaluation scheme can be applied to maintenance works and regulation of the length of life.
