Durability Study of Blower Motor Noise
블로워 모터 소음의 내구성 고찰

Abstract
As in many of the vehicle NVH issues, blower motor noise has been improved over the years through intensive R&D and production process improvement. Durability of motors, however, still has room for improvement according to customer surveys such as VDS. To investigate the noise issues of blower motors in view of durability, current production motors along with major competitor motors are tested. The noise after accelerated durability test shows that production motors are competitive in noise level with similar noise performance compared to initial measurement. The test result also provided guidelines to the durability development process.
