Abstract

This invention relates to a nautical propulsor comprising a shell (1) in which one or more propellers (2) are ducted, said shell (1) being rigidly connected to an axle (5), said propellers (2) being rotatively associated to said shell (1) by suitable coupling means and each of said propellers (2) having the rotor member (18) of a corresponding rotary electric motor associated thereto, the stator member (19) of said electric motor being rigidly connected to said shell (1), so that the rotation of said propellers (2) is rigidly coupled to the rotation of the corresponding rotor member (18), said rotor members (18) and associated stator members (19) being internally housed in the structure of said shell (1).
