| Abstract | This paper deals with the analysis of the torque behavior by means of finite element (FE) model. Since in synchronous PM machines, the current control imposes constant d- and q-axis currents, the FE solutions are strictly associated with the classical d - q axis theory. When using integral-slot windings, the torque computed by using the d - q axis theory is almost independent of variation of the flux linkage with the rotor position. This is not verified when fractional-slot PM motors are used. The iron saturation affects greatly the torque behaviour. In particular, the torque ripple increases significantly. A particular care to determine the average torque and the torque ripple is necessary when dealing with fractional-slot PM motors. An analysis of the iron saturation effect applied to different fractional-slot windings is provided, with a particular attention to the interior permanent magnet machines. |

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.
