摘要

The invention relates to a turnable propeller device for a ship, an offshore structure or equivalent. The propeller device comprises a vertical frame (11) which is mounted by means of bearings on a frame (5) of the propeller device, ship or equivalent so as to be turnable with respect to a substantially vertical axis of rotation (A-A). At the lower end of the vertical frame (11) a lower housing (12) is mounted which is formed by a closed chamber and in which one or more propellers (13) are fitted on a substantially horizontal propeller shaft. The propeller device (10) is provided with an electric motor (1) for turning the propeller device with respect to said vertical axis of rotation (A-A). A rotating part (2) of the electric motor producing the turning movement of the propeller device (10) is fixed directly to a turnable part (11, 14, 17) of the propeller device (10) and, similarly, a stationary part (3) of the electric motor is fixed to the fixed structure of the propeller device, ship, offshore structure or equivalent.
