61 -- PWT MAIN DRIVE STARTING MOTOR REPLACEMENT SOL F40650-00-R-0001 DUE 111099 POC Rick Stewart,(931)454-7844 WEB: 00R0001-PWT Main Drive Starting Motor Replacement, http://www.pixs.wpafb.af.mil/pixslibr/00R0001/00R0001.asp. E-MAIL: rick.stewart@arnold.af.mil, rick.stewart@arnold.af.mil. Background "Arnold Engineering Development Center's (AEDC's) objective is to replace PWT (Propulsion Wind Tunnel) Main Drive's (MD's) two existing large AC wound rotor induction motors and their associated liquid rheostats with two new synchronous motors with adjustable frequency electronic drive systems. The new motors will operate directly from the 60-Hz line after the drive train is bought up to full speed. The new motors will also operate from the new adjustable speed drives for starting and running below full speed. These new synchronous motors will be rated 60,000- Hp, with a 1.15 service factor, continuous duty, and must fit on the existing foundations. The replacement effort must be completed without major interference with ongoing test operations. AEDC is soliciting comments and suggestions for the best means of economically accomplishing our objective. Timing and funding are two major constraints. The effort must completed between October 1, 2000, and September 30, 2003. Funding will be available for three successive fiscal years, and is roughly equal for each of those years.
