Abstract

This paper presents results of the finite-element(FE) analysis of air-gap flux variation in induction motor when rotor vibration conditions occur. Accurate modelling and analysis of rotor vibration in the machine are developed using FE software packages, and search coils are used for measuring the flux. In the FE analysis, the induction motor with 380 [V], 5 [HP], 4P, 1742 [rpm] ratings is used. The results of FE analysis can be useful for on-line vibration monitoring of the motor.
