Diagnostic of induction motor using SFRA method

摘要

Paper deals with experimental measurements and analysis of frequency responses SFRA (Sweep Frequency Response Analysis) measured on induction motors. For the induction motors will be established the measurement procedure of frequency responses. For the applying method SFRA for the purpose of diagnosis and analysis of the rotating machine state there are processed the results from the standard used electric diagnostic measurements for the rotating machines. The purpose of the experimental measurements is implementation of the SFRA method for the failure identification that arise in power Induction motors with the rated power over 10 kW.
