| Abstract | The main aim of this paper is to study the ability of various electromagnetic fluxes to enhance the detection and localization accuracy of faults in a 35 kW cage-induction motor. Another aim of this paper is to study the modifications brought by various stators winding design to some of the asymmetrical air-gap electromagnetic flux density harmonics responsible for the detection of different faults. For this purpose, the following designs are considered: stator winding formed of no parallel branches, 2 and 4 parallel branches respectively. For the design consisting of no parallel branches we have considered the stator winding formed of one and two layers respectively. The studied faults consist of inter-turn short circuit in the stator winding, rotor-cage related fault (bars and end-ring breakage), eccentricities (static and mixed) and bearing failure. The relevant fault signatures of the electromagnetic fluxes are issued both from measurements and from two-dimensional numerical electromagnetic field simulations at steady state. When possible, the experimental verification for the ldquovirtualrdquo measurement signals provided by the numerical electromagnetic field simulations is achieved. |

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.
