PROPULSION DEVICE FOR VESSELS IN WATER COMPRISING ELECTRIC MOTOR/GENERATOR AND COMBUSTION ENGINE AND VESSEL COMPRISING SUCH A PROPULSION DEVICE

摘要

The present invention concerns a propulsion device (10) for vessels in water, said device (10) comprising: a connecting unit (11); an electric motor/ generator connected to the electric system of the vessel and comprising a stator (12) and a rotor (15) contained in the connecting unit (11); and a propeller with at least two blades (20) mounted on a propeller hub (13) placed in conjunction to the connecting unit (11) and rotation- ally connected to said rotor (15); whereby said device (10) is intended to be placed with the side of the connecting unit (11) facing away from the propeller (18) against the side of the stern part of the vessel facing the water. The invention is caracterised in that a shaft (17) extends from the combustion engine through the stern part of the vessel and further trough the connecting unit (11) to the hub (13) for operation of the propeller, and in that the shaft (17) from the combustion engine also is connected to the rotor (15) in the electric motor/ generator.
