摘要: Early detection and diagnosis of induction machine incipient faults are desirable for online condition monitoring, product quality assurance, improved operational efficiency. However, conventional methods have to work with explicit motor models cannot be used vibration signal case because their non-adaptation the random nature signal. In this paper, a neural network method is developed fault detection, using FFT. The model trained spectra detected from changes in expectation modeling error. effectiveness accuracy proposed approach detecting wide range mechanical demonstrated through staged faults, it shown that robust reliable system has been produced.
