| Abstract | In this paper effort is made for the torque ripple minimization of a 70 W, 24 Volt, 350 rpm, interior permanent magnet brushless DC (IPM BLDC) motor. The rotor pole shaping along with the pole shifting is analyzed. The results obtained from FE analyses have been discussed. The proper design and geometry of the motor reduces the cogging torque and the proper excitation reduces the mutual torque ripple. The torque ripple minimization using only the stator excitation makes the controller inefficient as well as costlier. Using the methods used in this paper, the torque ripple of the IPM BLDC motor is reduces and also the average torque is improved. In this method concept of magnet shifting is utilized for the torque improvement and rotor saliency is provided to reduce the cogging torque. Detailed analysis and explanation is given in this paper. The wide range of torque control by changing the switching intervals is an additional advantage of this design. |

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.
