摘要

1. Electrically driven propeller for watercraft with permanent excitation in a flange connecting the propeller blade ends and a stationarily mounted stator winding, in which the annular gap between stator and rotor is flooded, characterized thereby, that the propeller (1, 10) is at least in part arranged in a tunnel (4, 12), which is integrated into the stern of the ship and closed by a nozzle ring (6, 13) around the remaining circumference of the propeller, wherein shaft struts (8, 18) to the outer skin of the ship and to the rudder heel (17) and/or a shaft receptacle in the fixed part (15) of the rudder blade (16) serve to bear the propeller shaft (7, 14).
