Development of the Conceptual Design into an Engineering Solution: an Innovative Electromagnetic Linear Actuator for Marine Applications Case Study Part I: Architecture of the mechanical solution

This first part of the work describes an engineering solution to manufacture an electromagnetic linear actuator for moving rudders and fin stabilizers of military ships. The solution defines the transition from the conceptual design of the device initially studied from an electromagnetic point of view to a mechanical configuration that really works. This configuration has a high level of mechanical reliability. The structural problems that have been resolved with the proposed configuration are described. In order to validate the design choices discussed in this first part, the second part of the work illustrates the results of the numerical simulations performed by the structural finite elements method.
