Abstract

To improve the propulsion efficiency of a ship propulsion having a housing to be arranged on the bottom of the hull in a gondola-like manner, with a synchronous motor in the housing, at propulsion powers of approximately 10 MW, the rotor of the synchronous motor is designed as a permanent-magnet rotor, and the stator of the synchronous motor is fitted into the housing in a form-fitting manner to be cooled through the housing wall. An additional cooling device in the form of a fan or a spray device may be provided for each winding overhang.
