| Abstract | This paper deals with estimation of losses and efficiency of Switched Reluctance Motor (SRM), which is supplied from converter and motor is working under load conditions with different torques and at different speeds. The losses in a SRM consist mainly of stator winding losses and core losses. The winding losses are proportional to the square of the r.m.s current whereas the core losses are function of the excitation frequency and flux density, but the flux density depends on stator current waveforms. The different parts of the SRM core are subjected to the different frequency of flux reversals when the electric machine is operating at constant speed and load. This paper deals with investigation of copper losses including skineffect and iron losses in individual parts of SRM by means of two analytical approaches and by means of FEM. The efficiency of SRM and converter is measured and presented. The calculations of a real 3-phase 12/8 SRM are verified by measurements. |

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.
