Abstract (en)
An electrically driven propulsion system for a watercraft comprises an electric motor adapted to provide a mechanical power of at least 50 kW, a pulse inverter, a thrust bearing, and a transmission. The pulse inverter is electrically coupled to the electric motor and adapted to provide an electrical supply power of at least 50 kW to the electric motor. The transmission comprises a rotary shaft. The electrically driven propulsion system further comprises a common waterproof housing. The electric motor, the pulse inverter and an enclosed section of the transmission are arranged inside the common waterproof housing. An external section of the transmission is arranged outside of the common waterproof housing. The transmission is adapted to rotationally couple the external section of the transmission to the electric motor. The thrust bearing is mechanically coupled to the rotary shaft of said transmission and to the common waterproof housing. The thrust bearing is adapted to transfer a force applied to the transmission along an axial direction of said rotary shaft of the transmission to the common waterproof housing.
