New propulsion systems for boats, ferries and inland tankers are currently under[ds_preview] development. The delivery is scheduled for this summer.
Oswald Elektromotoren is focused on the development of hybrid and electric propulsion systems. The product range include water or air-cooled electric motors between 10 and 3,500 kW. For example the company supplied the propulsion system for the hybrid passenger ferry »Vision of the Fjords«. It consists of two lines of MAN D2862LE422 diesel-engines with coupling/clutch combination, electric motor and generator combination with flexible connectors on each side, advanced torque measuring equipment and monitoring for each operation modus. The electric motors are permanent magnet (PM) synchronous application that acts as generator or electric motor depending on operation conditions. Furthermore Oswald has supplied the tugboat »Telstar« with two pm motors of 800kW each, running on a hybrid thruster system together with more powerful diesel engines.
