Simotics DP motors are offered in an aluminium or grey cast iron housing, as standard version or in a special version for potentially explosive areas. They are available in a range of outputs from 0.18 to 200kW. The output range varies depending on the version: motors in an aluminium housing range from 0.37 to 45kW, in a grey cast iron housing from 0.18 to 200kW, and in the explosion-proof version for zones 2/21/22 from 0.37 to 200kW.
Their capacity for operation at up to 500V at the converter allows these line motors to form part of integrated drive systems, when used with a Sinamics frequency converter to enhance the efficiency of the entire drive train.
Marine motors do not fall within the scope of the European Motor Directive 640/2009, which defines the currently valid eco design regulations for electric motors in industrial applications. Yet these marine motors and the option of individual efficiency class selection are claimed to offer users enormous scope for energy saving. The absence of jumps in the shaft height between the efficiency classes IE1 and IE4 and the different outputs allow for significantly simplified upgrading or modernisation of overall systems.
All versions are pre-certified for use below deck by the ships classification and certification bodies DNV, GL, BV, LRS, RS, KR, ABS and RINA. Motors are also available in both a line variant and for operation at a converter.
The motors are used predominantly in shipbuilding applications, in ship compressors, feed pumps and winches. They are also used for port cranes and hydraulic pumps mounted on platforms.
