Electronic Drive Motors used in Naval Vessels Essay
Electronic Drive Motors used in Naval Vessels - Essay ExampleAccording to an analysis of various ships conducted by the US Navy, the electric pack propulsion ships habituates 10 to 25 percent lesser energy as comp ared to the traditional mechanical drive propulsion ships and thus are very likely to contribute to the Navys target of achieving environmental sustainability in usage of fuel by its vessels and by the naval equipment (Baldwin & Baldwin, 2008). There opposite advantages of electric drive propulsion system because of being newer in technology it can incorporate in it the latest technology and can easily declare the automated system and the various systems on the ship can be easily shifted to electric control and can easily be automated. Electric drive propulsion system can use the new propeller/stem configurations such as the podded propulsor which is very effective in increasing the fuel force of the ships due the improvements in the hydrodynamic efficiency of the shi ps (Hobart, 1911). The incorporation of the podded propulsor system can help in further saving the fuels up to 15 percent. Figure 2 Podded Propulsor http//accessscience.com/loadBinary.aspx?filename=YB001201FG0030.gif While incorporating an electric drive system in a naval vessel there are other concerns beside the propulsion of the ship and the electricity required for the control room electrical panels and boards. The guns and other credentials equipment installed on a naval vessel are also mechanically operated and in bless to convert the operation completely into an electric system the mechanical system installed on the ships will also needed to be converted to electric spring. nonpareil solution is to use an integrated electric drive system with more advanced push type known as the advanced induction labour AIM. But this type of electric motors can are only sufficient for the most primitive guns such as the DDG-1000 destroyer and cannot be used for the guns and security a nd combat equipments which require a larger power for their operation. The other technologies which can be used for powering the larger guns and combat equipment include permanent magnet motor (PMM) and high temperature super conducting synchronous motor (HTS). The conversion technology used should be efficient enough to convert and distribute the shipboard electrical power for the development of a propulsion system with more reliability, survivability and power quality. Permanent Magnet Motor A permanent magnet motor does not run through a field winding on the stator frame and thus relies on permanent magnets to provide the magnetic field against which rotor field interacts to pay off torque. The commutation under load on large motors can be easily improved by the use of compensating windings in series with the armature. The power consumption of the field winding can be easily eliminated by the use of permanent magnet fields (stators) and thus most of the large motors are dynamo types which utilize stator winding. The various operations on the ship and naval vessels powered by electrical
