Abstract
The ship's steering unit comprises a mounting which is part of the structure of the ship, and in which a rudder is pivotally mounted, the angular positioning of said rudder being servo-controlled by a motor. The motor is an electric motor comprising a stator rigidly fixed to said mounting, and a rotor rigidly fixed to said rudder. The steering motor is powered at variable frequency and at variable voltage, and it transmits the torque necessary for servo-controlling the rudder electromagnetically, i.e. without physical contact, thereby eliminating problems of wear. In addition, the steering unit is simplified by reducing the number of items of equipment making up said unit, thereby making it easier to install on board and contributing to making it more reliable.
