Abstract

The invention relates to a combined contra-rotating propeller electric propulsion system. The combined contra-rotating propeller electric propulsion system comprises a first motor, a shafting system,a first screw propeller and a rim type propeller. Propulsion efficiency is improved, the power of a large diesel engine which is high in price and limited in model selection range is delegated to a plurality of small-power generator sets through the mode of the electric propulsion system, so that a model selection range is expanded, and the initial installation cost of a power system is reduced. Arudder and propeller integrated type is adopted, the maneuverability of a ship is improved. The system is particularly suitable for medium and large ships.

Description

technical field

[0001] The invention belongs to the technical field of marine turbine propulsion, and in particular relates to a combined counter-rotating propeller electric propulsion system. Background technique

[0002] With the development of electric propulsion technology, electric propulsion systems are increasingly used on ships. The electric propulsion system is a propulsion type that is powered by a generator set or a battery, driven by an electric motor, and adjusted by a frequency converter or a controller. However, its electric propulsion efficiency is low and its structure is complex. The traditional propulsion type usually uses a high-power diesel engine to drive a large-diameter propeller through a shafting or gearbox. A single diesel engine is too powerful, large in size, medium in weight, and expensive, and the selection range is limited. Contents of the invention
