Test on Indicator-Motors, Navy Type "N"
Abstract
The sample motors were connected to a type "A" generator, furnished by the manufacturer, and tested for compliance with the specifications pertaining to accuracy, torque, 2nd oscillation. The electrical characteristics were then determined and the motors and generator were subjected to the 500-hour endurance test. Following endurance, the motors were again tested for accuracy. Then all bearings were cleaned and an accuracy test conducted on two of the motors. A final test of accuracy on these two motors followed a shock and vibration test. One motor was disassembled and checked against drawing, reference (d), and specification, reference (b).
