A Time-Frequency Analysis Method of Broken-Rotor-bar Fault Diagnosis in Squirrel Cage Asynchronous Motor Drived by Inverter
摘要
Abstract
The spectrum analysis of stator current was the main approach in the on-line detection for the rotor faults of squirrel-cage induction motor. For fault stator current manifestations of multi-component AM-FM condition, generalized demodulation time-frequency analysis method was applied to the motor stator current signal processing, and obtain the stator current’s time-frequency distribution of fault motor, then could find the stator current’s time-frequency distribution are clearly different between normal and fault condition. By analyzing the experimental results, the generalized demodulation time-frequency analysis method could be effectively applied to motor rotor broken bars fault diagnosis, and the effect was superior to other time-frequency analysis method.关键词
