| Abstract | The progressive cracking in the squirrel cage rotor bars of induction motors can lead to irreversible damage. For this reason, an early analysis of this type of faults is very necessary. Amongst the existing analysis methods, the Power Spectral Density (PSD) estimation by Periodogram, is considered as a very popular technique and is widely used in industry. However, this technique presents some drawbacks such as, a frequency resolution conditioned by the acquisition time and an identification for low harmonics quasi impossible. To overcome these drawbacks, a proposed method is presented in this paper, known as the Root-MUSIC method. This method used initially in the domain of RADAR for localizing mobile targets, is being applied to the domain of induction motors diagnosis. This method presents a high robustness to measuring noise and a frequency resolution largely superior to classical methods. In addition and in order to reduce the important computation time which is the main drawback of this method, Root-Music will be applied to only a specified frequency band; one that carries information about the sought fault. The obtained experimental results show the effectiveness and the merits of Root-Music and display the proposed improvements for cracked rotor bars fault detection in squirrel cage induction motor. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
