| Abstract | In this paper the task of optimization of the magnetic system velocity sensor devices for controlling the parameters of impact and machinery percussion is solved. The most widespread optimization criteria are the following: weight, size, and cost on a temporary basis, which respectively correspond to minimum response time, minimum winding time constant, maximum operational reliability, energy performance according to the maximum kinetic energy of the working body, maximum induced EMF in the coil, maximum traction, minimum energy consumption, and maximum efficiency. The reasoning of choosing optimality maximum sensitivity of the sensor, as well as minimum mass of active material as criteria is connected with using induction sensors for detecting impact energy at the impaction moment. The graph of the demagnetization-vs-return-line curve is presented. The position of the operating point of permanent magnet is determined by the intersection of the beam corresponding to the relative conductivity of the air gap and the return lines. The analytical solution for the flux measurement coil speed sensor, the electromotive force in the coil by opening the magnetic circuit, as well as the sensitivity of the inductive speed sensor are given in the paper. It is shown that the sensitivity of the sensor depends on the working gap, while the gap enlarging leads to its desensitization increase. |

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.
