Abstract
In this paper, a new approach monitoring rotor vibrations in a squirrel-cage induction motor is proposed. The air-gap flux variation analysis was done using search coils inserted in stator slots when rotor vibration conditions occur. An accurate modelling and analysis of air-gap flux variation in the induction motor are developed using finite-element(FE) software packages, and measuring the flux are made using search coils. In the FE analysis, the three-phase squirrel-gage induction motor with 380 (V), 5 (HP), 4 Poles, 1,742 [rpm] ratings is used. The results of FE analysis can be useful for on-line vibration monitoring of the induction motors.
