| Abstract | Great merits of utilizing Hall sensors as a position detector lie in the cost effectiveness and relatively easiness in installation. In this work, the axial component of the rotor PM edge field is detected by linear Hall sensors. The measured values by the two Hall sensors look like sin θ and cos θ, but contain a significant amount of third harmonics which causes angle estimation error. In this work, a phase locked loop (PLL) is utilized with the adaptive notch filter (ANF) for the purpose of filtering out the third order harmonics from the PLL input signals. The PLL yields both speed and angle estimates, and is used for speed feedback and coordinate change into the synchronous reference frame, respectively. Experiments showed satisfactory results in current and speed regulations. This kind of edge field detection method is advantageous, since the edge field is not strong enough to saturate the commercial Hall sensors and the edge field measuring is not affected by the stator current. |

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.
