Abstract
In view of problem that connectivity fault feature of motor was identified difficultly, on the basis of mathematic models and spectrum characteristic of motor connectivity faults represented by misalignment, looseness and base stiffness, empirical mode decomposition method was proposed to process vibration signal of motor. Diagnosis result is gotten according to fault feature frequency. The field application results verify effectiveness of the method.
