• Abstract

  The electrification of war-ship propulsion system is a very attractive solution, as it provides increased safety, survivability, maneuverability, precise and smooth speed control, reduced machinery space, low operation and maintenance costs, low noise and low pollutant emission levels. In this paper the basic principles of dimensioning for warships electric propulsion motors using finite element method are presented. The respective example which will be shown synoptically is a low rotational salient pole synchronous motor connected to the propeller axis directly (without gearbox).
