DD(X) Propulsion Motor Achieves Full Power

Alstom Power Conversion Incorporated (APCI) reports that the DD(X) Integrated Power System (IPS) Test Team has achieved full torque of over one million foot pounds on the Advanced Induction Motor (AIM) at the NGSS, NSWC Land Based Test Site in Philadelphia. This AIM is rated at 18.25 MW at 127 RPM.

Under contract with Northrop Grumman Ship Systems, Alstom’s propulsion solution includes the power dense motor controller called a VDM25000 and the Advanced Induction Motor. Both of these components have achieved full power during the testing. This propulsion system is the most power dense package demonstrated at full scale to designed torque and is now ready as the main propulsion solution for DD(X).

ALSTOM Power Conversion Inc., and its Pittsburgh based design, test and commissioning team are continuing to expedite additional testing at the Land Based Test Site.
