RUDDER PROPELLER OF DIRECT DRIVE SYSTEM Russian patent published in 2009 - IPC B63H5/125 

FIELD: shipping industry.

SUBSTANCE: invention refers to water equipment and can be used for spatial movement of the object on the surface or inside fluid medium and simultaneously providing the possibility of changing the direction of such movement. Rudder propeller is an electrically driven propulsion device of the floating object and includes screw blades, bladed propeller, and synchronous motor with constant magnets on the rotor. Synchronous motor stator can be rotated about vertical axis by means of other shaftless synchronous motors thus fixing the required position.

EFFECT: eliminating mechanical transmitting links, reducing consumption of materials, and improving manoeuvrability of movement and economy of useful energy conversion.
