Ship Motors


Built to withstand the toughest conditions, our motors used in the shipbuilding industry are robust, resistant to seawater and designed to have a long service life.

Our three-phase squirrel-cage motors can be produced as single speed motors up to four speeds in pole changing design, slip-ring motors up to two speeds. The surface- and water-cooled designs are intended for both long- and short-term operation and in different energy efficiency classes.
