Name Plate.pdf

This is an image of an industrial equipment nameplate from an Electro-Dynamics motor manufactured by General Dynamics Corporation located in Bayonne, New Jersey. The nameplate displays technical specifications for a direct current (DC) electric motor, including a frame size of 505-Y and a code designation of F/DES/D. The motor specifications indicate dual horsepower ratings: 40 HP at 1,135 RPM and 10 HP at 275 RPM, both operating at 440 volts. The amperage ratings are 51 amperes for the higher speed operation and 34 amperes for the lower speed operation. The nameplate notes that the motors are usable on 208-volt networks with appropriate amperage selection for overload protection, and it includes a serial number 128-84GA6 with a 100-phase, 3-phase designation. The equipment appears to be historical industrial machinery, likely from the mid-20th century based on the manufacturing style and General Dynamics affiliation during that era.
