"Motor Noise Analyzer" is an intelligent APP that integrates intelligent algorithms and knowledge base of motor engineering, which can complete data acquisition, composition analysis and noise source location of motor noise in one stop. Users can view the waterfall and spectrogram of noise in real time, and the APP will automatically label the frequency, intensity, order and source of noise, simplifying the analysis process. In addition, users can also generate professional diagnostic reports with one click, which greatly improves the efficiency and accuracy of motor vibration noise diagnosis.
