Abstract
This paper presents results of the finite-element(FE) analysis and experiment of air-gap flux variation in induction motor when rotor eccentricity vibration conditions occur. An accurate modeling and analysis of rotor vibration in the machine are developed using commercial FE analysis tool and search coils are used for measuring the actual air-gap flux. In the FE analysis and experiment, the induction motor with 380[V], 5[HP], 4r, 1742[rpm] ratings is used. The simulation and experimental results can be useful for rotor vibration monitoring of the induction motor.
