Abstract | This paper describes a method to analyze harmonic components of the air-gap flux density distribution and the torque of 3-phase cage induction motors, considering the influence of circumferential slot arrangement, stator winding pattern, and distribution of air-gap permeance due to leakage flux. The proposed method is based on an analytical model of the permeance and magnetomotive force distributions. The proposed method considers magnetic saturation caused by the main and leakage magnetic flux. As a result, the harmonic components of the torque in the starting condition can be determined quantitatively. From the comparison between the calculated and experimental results, the proposed method is shown to be appropriate and useful for quantitatively estimating harmonic torque for cage induction motors. |

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.
