MARINE PROPULSION INSTALLATION Russian patent published in 2016 - IPC B63H20/00 B63H23/24 H02K9/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to designs of ship electric propulsions of ship electric propulsion systems. Proposed propulsion system comprises encased in sealed streamlined body drive motor, pipe, which connect drive motor with vessel hull, tractor and pusher propellers. Drive motor is bi-rotary, with rotating in different directions stator, which is connected with tractor propeller and rotor, which is connected with pusher propeller. Stator and rotor shafts are aligned and come out of housing of drive motor in opposite directions. Stator of drive motor on outside of the birotatory motor contains current-collecting ring and bearings, resting on motor housing. To collector rings adjoin brushes with brush mechanism secured at ship hull. On inner side of stator between stator and rotor bearings are installed, in which rotor rotates.

EFFECT: higher efficiency, reduced weight and dimensions of the propulsion motor, increased capacity and capacity of ship is achieved.
