A Methodology for the Detection of Broken Rotor Bar Fault Of Induction Motor

Ganesh Morthy


Motor current imprint examination has been adequately used for issue determination as a piece of insincerity motors. Regardless, this procedure does not for the most part finish incredible results when the pace or the load torque is not predictable, since this cause minor takeoff from the motor slip and fast Fourier change issues appear due to non-stationary sign. This paper likely portrays the effects of rotor mellowed bar blemish up the stator current of impelling motor working under non-unfaltering burden conditions. To perform this, broken rotor bar imperfection is reproduced in an examination office and its effect on the motor back and forth movement has been focused on. To break down the broken rotor bar accuse, another methodology in light of wavelet change is associated by using 'Labview 8.2 programming' of National Instrument (NI). The conclusion procedure was performed by using the virtual instruments. The speculative reason of proposed procedure is exhibited by examination office tests.
