Design of Electrical Machines for Maritime Propulsion Systems

Design of Electrical Machines for Maritime Propulsion Systems (Cooperation with Fincantieri)

In the last years, electric propulsion systems are gaining attention in the maritime propulsion sector, both as full-electric propulsion and as a part of a hybrid propulsion system, thanks also to their superior efficiency and the higher flexibility offered in the onboard space management. The design of the propulsion eMotors is a challenging task, because of the high power and torque required from the application and the weight and volume limitations, related also to the vessel design. The high torque of the application and the limited voltage onboard allows the consideration to several solutions for electric motor design, different from the standard induction motors or synchronous generators, as anisotropic PM motors, multiphase windings, special cooling system and so on.Currently, PEIC is cooperating with Fincantieri on the definition of guidelines for the preliminary design of eMotor (LinkedIn post). This research will be useful for Fincantieri to study the effect of different propulsion eMotor solutions at the very early stages of the vessel design.
