Abstract | Firstly, the topology and operation principle of the permanent-magnet BLDC motor for automatic door are researched in the paper. A method for decreasing cogging torque by cooperating of pole number and slot number is given. To increase the inner space utilization rate and the motor efficiency, the double-layer-and-short-pitch windings are employed. Secondly, taking terminal voltage as input, transient electromagnet field of a six poles permanent-magnet BLDC motor was calculated and simulated through the 2D circuit-field coupled time-stepping finite element method. Then, based on the driving system of the permanent-magnet BLDC motor, the experimental verification of the research work was completed. Finally, Both simulation and experimental results are given to verify the validity of the proposed machine. The application of the motor will accelerate the popularizing process of the permanent-magnet BLDC motor in the industrial field, and show its broad development prospect. |

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.
