Rapid planning and acceptance with pre-certified marine motors

02.04.2015
  • Motor designs with outputs ranging from 0.18 to 200 kilowatt (kW)
  • Choice of efficiency classes from IE1 to IE4 enables significant energy savings
  • Usable in combination with converters as an Integrated Drive System (IDS)

With Simotics DP, Siemens is offering below-deck marine motors based on the proven 1LE1 platform. With an aluminum or grey cast iron housing, as a standard version or in a special version for potentially explosive areas, these motors are available in a wide spectrum of outputs ranging from 0.18 to 200 kW. Their capacity for operation at up to 500 volts (V) at the converter allows these line motors to also form part of Integrated Drive Systems, and so enhancing 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. Despite this, with its Simotics DP marine motors portfolio and the option of individual efficiency class selection from IE1 to IE4, Siemens is still offering 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 available make for significantly simplified upgrading or modernization of overall systems, providing the assurance of a secure high-level investment over the long term. The integrated Simotics DP motor product spectrum with outputs ranging from 0.18 to 200 kW is based on the familiar 1LE1 platform, and also includes motors for potentially explosive atmospheres (ATEX motors).

The motors are available with an aluminum or grey cast iron housing. The output range varies depending on the version: motors in an aluminum housing range from 0.37 to 45 kW, in a grey cast iron housing from 0.18 to 200 kW, and in the explosion-proof version for zones 2/21/22 from 0.37 to 200 kW. 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.

This saves time for the customer primarily during planning and acceptance of the completed ship. In terms of planning and its flexibility, the user also benefits from the availability of the motors in both a line variant and for operation at a converter. Used in combination with a Sinamics frequency converter, the Simotics DP motor creates an Integrated Drive System (IDS), so additionally increasing the energy efficiency of the drive independently of the energy efficiency class of the motor itself.

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.

As pre-certified Simotics DP marine motors are available in a choice of efficiency classes from IE1 to IE4, customers are able to benefit from enormous energy saving potential. The different versions and output ranges are designed to comply with widely differing requirements.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
