System-Level Consideration and Multiphysics Design of Propulsion Motor for Fully Electrified Battery Powered Car Ferry Propulsion System

The Korean government is facing growing concern over the increasing levels of fine dust. A significant contribution to this problem comes from coastal vessels. To mitigate this, an electric ship propulsion system has been proposed as a solution reduce air pollution. application fully in challenging due size, capacity limitations, and cost investment battery system. address challenges limitation initial costs, development supply removable systems (RBSSs) for electrified powered (F-EBP) car ferries are studied. permanent magnet synchronous motor (PMSM) F-EBP ferry using roll-on/roll-off-type RBSS developed work. Firstly, concept discussed, specifications provided. Secondly, design electromagnetic analysis performed finite-element (FEA), where heat sources including copper loss, core PM loss calculated. Mechanical also considered. Finally, thermal network built considering lumped-parameter model. results indicate that operates within safe region can perform well rated working conditions.
