Marine main generators and propulsion motors up to 40 MVA, 0.4–15 kV

Description

The company produces a full range of individually designed marine generators and motors up to 40 MVA: asynchronous, synchronous and permanent-magnet types, for main power plants, electric propulsion installations and shaft generators. The machines are oriented to marine system integrators and shipyards; the company has supplied generators and motors since the 1930s and has a separate line of high-technology machines for naval forces, including low-noise solutions. Characteristics. The power range is up to 40 MVA and the voltage range from 400 V to 15 kV. All types of cooling are available, with sleeve or rolling bearings; the windings are impregnated with VPI (vacuum pressure impregnation) technology. Synchronous generators are designed for all electrical parameters of the ship network: operation at constant or variable rotational speed, behaviour during transients and short circuits, and reactive power sharing during parallel operation. Propulsion and special motors are designed for operation from frequency converters, taking into account the shape of the drive output voltage. All requirements of the classification societies are taken into account in the design. Versions: main diesel generators and generators for electric propulsion installations, propulsion motors, special motors and generators, offshore solutions, and machines with requirements for low noise and vibration. Each solution is adapted to the customer requirements for quality and competitiveness. For the modes of power take-off and power feed on the propeller shaft, separate low-speed shaft generators (PTO/PTI) are produced. Electrical machine production is concentrated at the plant in Reinosa (Spain), where testing and service are also carried out. Applications are cruise ships and ferries, offshore and special vessels, icebreakers, warships and drilling vessels.
