"Motor Noise Analyzer" is an intelligent APP that integrates intelligent algorithms and electrical engineering knowledge bases, which can complete data acquisition, component analysis and noise source localization of motor noise in one stop. Users can view the waterfall diagram and spectrum diagram of the noise in real time, and the APP will automatically label the frequency, intensity, order and source of the noise, which simplifies the analysis process. In addition, users can also generate professional diagnosis reports with one key, which greatly improves the efficiency and accuracy of motor vibration and noise diagnosis.
