Curtiss-Wright Electro-Mechanical Corporation (CW-EMD) is a leader in the supply of critical function, electro-mechanical products. Innovative system and product solutions are based in the rich legacy of over 100 years of Westinghouse technology. More than 50 years ago, CW-EMD built critical function pumps for the first nuclear powered submarine, the USS Nautilus. Today, CW-EMD continues to develop, design and supply advanced electro-mechanical solutions forthe US Navy, including the Navy's most advanced motors, generators and secondary propulsors. Within the nuclear utility industry, CW-EMD supplies reactor coolant pumps, seals, motors and control rod drive mechanisms. Recently, CW-EMD expanded its product offering to include both subsea pumping and hazardous waste pumping systems.

Innovation

From the very beginning, innovation has been the hallmark of CW-EMD's accomplishments. Formed in 1952, CW-EMD designed and manufactured critical application pumps used in the first nuclear submarine, the USS Nautilus. These pumps were developed using an innovative concept that produced zero-leakage pumps that require virtually no maintenance. Today, these critical application pumps are used throughout the US Navy. Our new motor and pump designs have established new standards for performance and reliability.

CW-EMD's unique motor technology has led to other product innovations. Our Integrated Motor Propulsor System integrates a number of advanced technologies, a unique canned induction motor, material selection and deployment flexibility. The development and qualification program for this rim driven propulsor was so successful that the prototype unit was used without any post-testing modification or refurbishment.

A similar product innovation utilizing our canned motor technology is the hazardous waste pump. This integral submerged canned motor/pump eliminated the need for externally supplied cooling and lubricating systems. The long-life, highly reliable design has dramatically contributed to life cycle cost savings in the transfer of hazardous wastes.

Our rich Westinghouse large electric machine technology legacy has enabled advanced designs for the ship service generators that power the U.S. Navy's fleet. CW-EMD builds the Navy's largest and most advanced high-speed generators. This record documents EMD's ability to achieve major technical advances and promised performance levels while maintaining our hallmark reliability.

The recent opening of the CW-EMD Technology Center enables Westinghouse Science and Technology Center scientists and engineers to continue advancing the technology that the Westinghouse name has come to represent.

Critical Function

CW-EMD is a fully integrated supplier of advanced, critical function motors, generators, pumps and propulsors to the Navy and commercial industry. EMD products, processes and personnel meet the highest ISO 9000, ASME and military standards. These critical function applications require highly reliable, shock or seismically qualified components, long life expectancy, low maintenance and operation in harsh and demanding environments.

The CW-EMD approach is design by analysis, verification through testing. In advancing Navy machinery performance to new levels, we have been assisted by the world-class rotor and electrical test facilities that were constructed at CW-EMD in 1990. Our Integrated Electric Machine Test Facility was specifically sized to accommodate the qualification of Navy electric drive systems. The capabilities of our one-of-a-kind generator Rotor Test Facility were designed to comply with the stringent requirements of the Trident program.

CW-EMD also has extensive design, manufacture, test and operations experience in commercial markets. CW-EMD produces boiler circulation pumps and motors, reactor coolant pumps and motors, control rod drive mechanisms and primary loop valves that operate in commercial utility power plants the world over. CW-EMD manufactures, refurbishes and tests commercial Reactor Coolant Pump (RCP) motors in the 4,000-10,000 HP range and has fabricated a 70 foot tall, 85,000 GPM pump and 17,500 HP synchronous motor with variable speed drive.

Advanced Electro-Mechanical Solutions

From problem definition and concept development to manufacture and life cycle support, CW-EMD's successfully delivered advanced electro-mechanical solutions across a wide spectrum of industries. From advanced pumps that transfer hazardous waste or high temperature fluids, to integrated propulsion motors, advanced generators and high power electronic control and conditioning equipment, CW-EMD's capabilities enable complete system definition, design and supply.

A first-of-a-kind, submerged canned electric motor and multi-phase pumping system for deep-sea oil recovery was recently delivered. This new product requires high reliability motors in the 1,000 - 5,000 HP range. CW-EMD has also completed preliminary design studies for a very large (over 10,000 HPO) canned motor for nuclear reactor pump applications.

This history of successfully achieving advanced electro-mechanical performance in critical application machinery makes CW-EMD a unique resource for the U.S. Navy and its electric drive system development program. The A Rand Corporation study on the military industrial base commissioned by the General Accounting Office in the early 1990's referred to CW-EMD as a critical national resource.
