DRS Technologies Successfully Completes Testing of Permanent Magnet Motor System at US Navy Land-Based Test Site

PARSIPPANY, N.J. --- DRS Technologies, Inc. announced today that it has successfully completed full-power testing, as required by the U.S. Navy, of its power-dense Permanent Magnet Motor (PMM) and drive at the U.S. Navys Integrated Power System (IPS) Land-Based Test Site (LBTS) in Philadelphia, Pennsylvania. Engineering, design and development of the motor and drive were contracted to DRS as part of the DD(X) destroyer, now DDG 1000 Zumwalt-class Multi-Mission Surface Combatant, Engineering Development Model (EDM) program for inclusion into the IPS testing program.>> DRS Permanent Magnet Motor provides 36.5 megawatts (approximately 50,000 horsepower) and over two million foot-pounds of torque in a dual-ring design. During testing, the motor ran at full power on a single ring at 18.25 megawatts, the maximum load available at the Land-Based Test Site. This test validated the thermal and electrical operation of the motor and drive.>> This milestone achievement validates that the companys Permanent Magnet Motor technology is a viable alternative for naval ship propulsion applications. DRS Permanent Magnet Motor technology offers several benefits and advantages to the Navy over conventional ship propulsion systems, including high power density resulting in lower weight and volume than traditional motors, increased operating efficiency resulting in fuel savings, increased power and improved performance.>> DRS has now embarked on an enhanced design of the motor, which incorporates lessons learned from the EDM testing. The companys evolutionary motor design will provide additional benefits to the Navy, including lower weight, decreased volume and greater performance.
