| Abstract | Switched reluctance machines (SRMs) with modular or segmented structures normally have light weight, low cost, easily manufactured and improved fault-tolerance capability. In this study, two novel three-phase modular SRMs (MSRMs) with the same E-shaped stator modules and different rotor topologies, namely, segmented rotor and conventional rotor are evaluated and compared. The basic machine topologies and simplified magnetic equivalent circuit (MEC) are presented first. The static electromagnetic characteristics of two MSRMs such as flux distribution, phase flux linkage and inductance, electromagnetic torque, and so on, are computed and compared by three-dimensional finite-element analysis. Then, the dynamic performances including steady state and transient operations of two MSRM drives are evaluated and compared. The corresponding predictions and comparisons indicate that the segmented rotor topology has less iron consumption, higher torque density and power density and lower torque ripple, which is preferred for the three-phase MSRMs. Finally, two MSRM prototypes with segmented rotor and conventional rotor are manufactured and tested for experimental verification and comparison. The experimental results of static flux linkage, steady state and transient performances of two MSRM drives are presented and compared, which verify the analytical MEC model, finite element analysis and the corresponding predictions. |

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.
