Baumüller’s DST2 motors receive certification from Lloyd’s Register

The Nuremberg-based drive specialist Baumüller continuously works on solutions for electric mobility. For some time now, the company has cooperated with the Dutch enterprise Hybrid Ship Propulsion B.V., which equips ships with hybrid drives and relies on high-torque motors in the DST2 series from Baumüller in the process. The British classification company Lloyd’s Register has now confirmed that the motors meet the specific requirements of inland vessels. Lloyd’s Register has been testing components or complete systems in ship construction and other sectors since 1760 and has now certified the DST2 motors in the 315 and 400 sizes.

Robust for high demands

The water-cooled direct drives are built with the protection class IP 54, are dirt-resistant and run quietly. Thanks to their compact and robust construction, the motors take up little space in the engine room and are well-suited for the rough conditions on the water. The motors can be ordered with optional wing mounts, which means that the feet are positioned diametrally on the outside diameter of the motor and thus make it easier to integrate the unit into the ship design. High torques, good concentricity properties and energy efficiency thanks to a high degree of effectiveness make the high-torque motors ideally suited for demanding applications. Since the full torque is already available from the start in the lower rotational speed range in hybrid ship drives – compared to purely diesel-operated ships – this also significantly improves the maneuverability.

In inland navigation, hybrid drive systems have recently developed into a popular and efficient alternative, not only because of new legal regulations for environmental protection. Numerous advantages make the combination of diesel motor and electric motor particularly attractive for ship navigation. It is possible to save up to 20% fuel, for example, and there are reductions in pollutant emissions, noise and vibrations. Different drive modes, such as purely electrical operation, running only with a diesel motor or a combination of both options give the captain greater flexibility and adaptability to external circumstances.
