| Abstract | This paper addresses the problem of diagnosing cage motors with double bar breakages involving non-consecutive rotor bars. As it is stated in previous works, the conventional diagnosis approaches fail when diagnosing this fault for certain relative positions of the broken bars. This work is focused on the study of the high order harmonics of the airgap-field produced by the fault; simple mathematical expressions are deduced which enable to evaluate the influence of the relative position of the broken bars on the amplitude of the fault related components (Left Sideband Harmonic and other high order fault components) of the stator current. These expressions demonstrate to be useful for confirming the diagnostic in uncertain cases; they are validated by finite element simulations and laboratory tests, using different diagnosis methodologies based both on steady-state and on transient analysis. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
