3-D Laser Vibration Measurement for Nose and Vibrating Mode Analysis of Fan Motor in a Vacuum Cleaner

진공청소기용 팬모터의 소음 및 진동모드 분석을 위한 3차원 레이저 진동측정

Noise cause is dividing to fluid noise by exhaust flow of fan and vibration noise by rotational vibration of motor. Until now, measuring method has been used to measure vibration by the accelerometer, this method has been not measured for the vibration in some parts of brush and commutator because of motor construction. This research was purposed on the accurate analysis. using laser vibration analyzer, of noise cause against the difficult part in old times. By using this measured data, we would like to use for the design of silent motor.
