Intelligent drives for hybrid over and underwater propulsion

High performance, integral drive systems where the PM motor and the power pack are integrated in the same sealed frame are constantly developed for naval and underwater propulsion, both for hybrid and full electric vessels. Power packs include battery recharging, dock power supply, auxiliary inverters for the Ac supply of small vessels, as well as, for mission critical units, full redundancy and super high system efficiency > 95%. Ongoing developments include rim drives for hubless thrusters, up to MW level.
