A New Solution to Improving Performance of Diagnosing the Broken Squirrel-Cage Rotor Bars of Asynchronous Motor
Jie Li · Journal of Xi'an University of Technology · 2002
On the basis of introducing the fundamental theory of stator current spectroscopic analysis for diagnosing the broken squirrel-cage rotor bars of asynchronous motor and by aiming at the problems in the traditional spectroscopic analysis, the power-frequency counteracting method based on complex number filter is presented. The simulation and analysis results show that the solution greatly increases the signal-to-noise ratio and makes the stator current spectroscopic analysis more effective and reliable.
