| Abstract | The undesired harmonics in the stator magnetomotive force (MMF) of the permanent magnet servo motor (PMSM) have a lot of adverse effects on the operation performance of the motor. The stator shifting combination is a powerful means to weaken or even eliminate the undesired harmonics in the stator MMF. By using the stator shifting combination, the common 9-slot–8-pole, 12-slot–10-pole and 15-slot–10-pole combination schemes are transformed, and the 18-slot–8-pole, 24-slot–10-pole and 30-slot–10-pole combination schemes are obtained. With the three new schemes, three PMSMs are designed under the same working condition, and their electromagnetic performance, temperature field and NVH are analysed and compared by multi-physical field finite element analysis. Among the three motors, the harmonic content of back electromotive force, torque ripple and cogging torque amplitude of the 24-slot–10-pole motor is the lowest, the loss and flux-weakening performance are between the other two motors. What's more, it has low radial electromagnetic force harmonic content, and the sound pressure level of electromagnetic noise is moderate. Taken together, the 24-slot–10-pole scheme is more reasonable for PMSM. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
