| Abstract | This paper comprehensively investigates 3-phase, 12-slot, and 8-pole switched reluctance machines (SRMs) with different winding configurations, e.g. double/single layer, short/fully pitched. Comparisons in terms of self- and mutual inductances, and on-load torques have been carried out using 2-D finite element method (FEM) for conventional and mutually coupled, double layer winding switched reluctance motors (SRMs) as well as fully-pitched and single layer winding SRMs. The numerical results have shown that the fully pitched switched reluctance machine (FPSRM) has the highest inductance variation against rotor position and hence produces the highest on-load torque if the machine is not heavily saturated. However, its significant longer end-winding will leads to higher copper loss. This can eventually jeopardize its torque vs copper loss performance. To boost torque production while maintaining short end-winding and hence low level of copper loss, two short-pitched, single layer winding SRMs with similar winding configurations to those of conventional and mutual coupled, double layer winding SRMs can be employed. It is found that for the same copper loss and without heavy magnetic saturation, both single and double layer mutually coupled SRMs can produce higher on-load torque compared to their conventional counterparts. Moreover, single layer mutually coupled SRM can achieve comparable torque against copper loss performance to the FPSRM but with much shorter end-winding and also smaller volume. |

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.
