Permanent magnet shaft generatorsFor shaft generators, our mechanical solution based on permanent magnet generators (PMG) and frequency converters allows the auxiliary generators to be off most of the time and enables the ship to operate at variable speed while producing electricity. Higher efficiency
A PM machine gives high-efficiency performance over the entire operating range, significantly cutting back on fuel consumption. A PM machine is typically 2–4% more efficient at full load and 10% more efficient at part loads compared with induction machines. These efficiencies result from a lack of current losses in the rotor, the absence of an exciter and reduced winding losses. High power density
The synchronous PM machine contains Neodymium-Iron-Boron (NdFeB) magnets, materials with a very high flux density, which makes them ideal for variable speed generators throughout the entire speed range. The magnetic field is created with almost zero losses. Design flexibility
Thanks to the improved high density, a PM machine can be more compact, lighter in weight and smaller in size. This leads to greater flexibility with the limited space available in ship configurations. Operational reliability
PM machines have proven their high reliability and durability under extremely harsh operating conditions in many industrial applications. They deliver excellent performance with corrosion resistance and temperature tolerance. With advanced thermal management, operational temperatures can be kept low, which in turn, assures an extended lifetime of the machine. Widest range available
The Switch product portfolio of brushless PM synchronous machines is the widest in the market. We offer drive trains from 1 MW to 10 MW at low, medium and high speed. The machines can be used either as a generator or as a motor.
Our PM machines comply with the standards of leading classification societies in the world. They have been tested, approved and certified to ensure highest possible reliability of the vessels and to comply with the strict international safety and environmental standards. Frequency converter superioritiesOptimized for best efficiency
The Switch frequency converter is based on insulated-gate bipolar transistors (IGBT) with advanced vector co***ol technology. It is optimized to work with PM machines for the best overall system efficiency. Our converters offer a modular, lightweight design, which enables efficient use of space within the vessel. Active front-end speed co***ol
With active front-end (AFE) frequency drive technology, The Switch converter enables Power Take In (PTI) and Power Take Out (PTO) modes, while allowing a shaft generator to operate at variable speed. This technology enables the use of a PM machine to be operated as a motor or a generator according to the application requirement. Liquid cooling and thermal management
The Switch frequency converter is designed with liquid cooling and exceptional thermal management. This results in a more compact size of the converter, which makes it easy to locate within limited vessel space. Reliability in harshest conditions
The frequency converter features a rugged IP54-class panel. It is designed to be used in harsh environments, such as those on open sea. It is also easily accessible for installation and maintenance.
