Motor Design and Build

The Naval Surface Warfare Center Carderock Division (NSWCCD) requires a contractor to design, fabricate, assemble, and test a new water-cooled electric motor for model testing at the Large Cavitation Channel. The motor must meet specific performance criteria, including at least 2,600 ft-lbs of torque from 0 RPM to a 900 RPM base speed, with a maximum slip of 2% and capability to run at 1100 RPM at constant horsepower. Electrical specifications include 480/460 VAC, 3-phase AC, 60 Hz, and compatibility with variable frequency drives up to 600 VAC. Mechanical constraints involve a maximum length of 72 inches, fitting through a 22-inch diameter opening, and all connections on the non-drive end. The motor must operate for 12 continuous hours at 85°F ambient air and withstand air pressure changes from 14-60 PSIA. It also requires temperature sensing capabilities for windings and bearings, and a rigorous acceptance test. The contractor must also provide documentation of similar prior experience and adhere to administrative requirements including design reviews, fabrication authorization, and delivery to NSWC Carderock within a one-year performance period.
