초록

Reliability of automotive parts has been one of the most interesting fields in the automotive industry. Especially, blower motor driving blower for automobiles is important part because of sustaining grateful environment inside the car for the driver and the passengers. It is the small dc motor. Therefore, we have dealt with the reliability life test procedure of blower motor. The failures such as wear-out of brush, bearing damage, motor coil burnout are caused by the electrical and mechanical operating blower motor. In this research, we have qualitatively selected the efficient test items through the analysis of the life and potential failures of blower motor. So, blower motor itself requires an estimation of life causing failure of brush wear out in order to operate the system safely. We have carried out life test for blower motors. The result is established by employing the weibull plot. We calculated the life of blower motor to the experimental result.
