| Abstract | Affordability, redundancy, as well as space, weight, and energy savings are main issues on board ship. Classical oil-powered onboard actuators used for steering gears (rudders, roll-stabilizing fins) are usually cumbersome, weighty, low-efficiency and costly plants, also requiring an heavy maintenance burden. The Italian Navy recently committed a research project to the University of Rome-Sapienza, aimed to define innovative inverter-fed full-electric actuation systems in alternative to the hydraulics. The new actuators had to guarantee the required dynamic performances, i.e. very high torques/forces at very low speeds, besides high affordability, redundancy, and, mostly, high efficiency. This paper proposes a new high-thrust permanentmagnet linear actuator for direct-drive of steering gears, through an appositely designed rotary-prismatic coupling. Mechanical and electrical drive sizing are shown, and force, speed, and efficiency performances are analyzed and compared with those of the original hydraulic plant. The proposed actuator will be verified by tests on a reduced-scale laboratory prototype in the final steps of the research program. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
