| Abstract | This paper presents design reconsiderations of the proposed permanent magnet hybrid excitation motor (HEM) for high-speed main spindle drive in machine tools based on detailed analyses of experimental results obtained using prototype machine. The proposed HEM has been intentionally designed using 3D-finite-element analysis (FEA) for the target application. Although the basic working principle of HEM has been proven by the experimental results, the induced voltage waveforms measured have shown a large deviation from those computed by 3D-FEA. In particular, the induced voltage distortion due to fifth harmonics has been a primary factor which has degraded the drive performances of test machine. After checking the differences between the designed drawing and the real one being taken into account of real manufacturing, design reconsiderations are conducted to the tested HEM using 3D-FEA. As a result, it is demonstrated that 3D-FEA results reconsidering the differences of the design parameters, the stator pole shoe and the stator teeth, are relatively good agreement with the tested results. |

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.
