Abstract
A propelling and driving system for boats having an outboard rudder propeller. The system provides the boat with reliable and comparatively good maneuverability. The system comprises at least two rudder propellers, each having driving motors configured in the form of a permanent magnet-excited synchronous machine. The stator winding of each synchronous machine has three winding phases connected to a three-phase alternating current, which are connected to the supply system of the boat. A modular controlling and regulating device comprising standardized modules is provided for each of the rudder propellers.
Claims35
A drive and propulsion system for a ship, comprising:
- at least one steering propeller arranged outboard and having a rotatable azimuth module and a power transmission device, and a propulsion module arranged as a pod on the azimuth module having a drive motor for the propeller, the drive motor being in the form of a permanent magnetic synchronous machine with a stator winding having at least three sections connected to a 3-phase alternating current source and connected via the power transmission device to a converter arranged in the ship and connected on an input side via converter transformers to a ship's on-board power supply system, whereby a digital control and regulation device comprising standardized assemblies in a modular form being provided for each steering propeller.
