Abstract | The distribution cable was often used as armature winding in modern high voltage motor. The electric field in windings was distributed more evenly and the insulating property of motor was then advanced by use of winding cable. But corona discharge may still exist in this kind of cable winding motors. The model of single phase winding cable and linear motor stator was built firstly. The electric field of cable in stator slot and near the outlet of stator slot was analyzed. In addition, we studied the end-region electric field of linear motor. Based on the electric field distribution, the possible sites were analyzed where the corona discharge may firstly occur. The research results indicate the electric field was distorted near the outlet of stator slot and end region of motor, and the field intensity was increased here. At the same time, when the cable sheath was not well contacted with the ground system, corona discharge may occur. So near the outlet of stator slot, end-region of motor and bad grounding spot of cable shield the corona discharge will first occur. At last we discussed some ways to decrease the probability of corona discharge in linear motor. |

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.
