Abstract
A marine propulsion system may include at least one electric motor and a converter-fed electrical power supply. The at least one electric motor may be arranged in a propeller shaft pipe at a stern of a vessel for driving at least one vessel propeller, and may include at least one drive machine for driving at least one generator.
Claims42
A marine propulsion system, comprising:
- at least one electric motor arranged in a propeller shaft pipe at a stern of a vessel for driving at least one vessel propeller;
- a converter-fed electrical power supply to supply electric power to the at least one electric motor, including,
- at least one drive machine for driving at least one generator, wherein
- at least one of the at least one electric motor and the at least one generator is a three-phase synchronous machine, and
- at least one of the at least one electric motor and the at least one generator includes a rotating field winding composed of high-temperature superconductor (HTSL) wire, each rotating field winding being arranged in a cryostat for cryogenically cooling the rotating field winding to a temperature between 15 and 77 K.
