Electric motors represent a technically proven and increasingly popular option for marine and hence naval, megayacht or research vessel propulsion systems. With improved frequency stability and efficiency, this is faciliated by the power electronics used nowadays and installed between the onboard generator and the onboard power system. An alternative to electrical direct-drive systems with their large, bulky and heavy motors running at propeller speed, are high-speed motors with reduction gear units. A perfect realization of this concept is RENK's AED where the electric motor and the gearing are installed on a common raft elastically mounted, The special advantages: compact footprint, easy installation, low weight, and incomparably quiet operation.
