Provided is a synchronous electrical machine that includes a stator and a wounded rotor, the stator having a plurality of phases, each phase comprising coils connected together and magnetic stator poles cores fixed on a stator frame and evenly distributed along a stator diameter, each coil being wounded around a different magnetic stator pole core to form a magnetic stator pole, each phase comprising a same number of magnetic stator poles, the magnetic stator poles of each phase being disposed in the stator frame to form a concentric winding stator. The rotor includes a plurality of magnetic rotor pole cores evenly distributed around the rotor and rotor coils, each rotor coil being wounded around a different magnetic rotor pole core to form a magnetic rotor pole.

Synchronous electrical machine and boat comprising such a machine

The disclosure provides a pod propulsion system including first and second counter rotating propellers for providing thrust to propel a marine vessel. The pod propulsion system includes a first electric motor (i) for rotating the first propeller and (ii) electrically coupled to a first drive, the first drive being configured to control the first motor and a second electric motor (i) for rotating the second propeller and (ii) electrically coupled to a second drive, the second drive being configured to control the second motor. The first and second drives respectively control the first and second motors interdependently.

Counter rotating propeller pod electrical arrangement

Provided is a pod propulsion system including first and second counter rotating propellers for propelling a marine vessel first and second propeller modules, each including an electric motor having a driving-end configured to rotate the first and second propellers, respectively. Also included are first and second gondolas, each (i) for housing a respective one of the first and second electric motors and (ii) including a boltable interface formed along a lengthwise direction of an extremity of the gondola. A strut (i) connects the first and second gondolas to a hull of the marine vessel (ii) including first and second boltable interfaces. Each of the boltable interfaces of the strut is configured to form a bolted joint interface with a corresponding one of boltable interfaces of the first and second gondolas.
