Motor Noise and Vibration Test Research
Abstract: Some factors, such
as friction, vibration, and so on, can result in the fault and abnormal noise
in the motor. Based on the detection and analysis of noise and vibration, we
can identify and eliminate the faults of the motor. This is helpful not only to
ensure the completion of production tasks, but also to prevent accidents. In
this paper, we briefly introduce the motor noise generation principle. A laptop
computer and LabVIEW software are used to design the experiment system to
detect and analysis the noise and vibration of motor. External microphone and
computer with sound card constitute noise detection system hardware. Vibration
sensor and the data acquisition card constitute vibration detection system
hardware. LabVIEW software combined with FFT analysis is used to realize the
noise signal acquisition, recording and spectral analysis. Detecting and
analyzing the noise of the permanent magnet DC motor and three-phase
asynchronous motor proves that the motor noise and vibration detecting
experimental platform is fully meet the requirements of motor test and
research. This detection and analysis system has a good man-machine interface
and strong operability.
