Description

Notice ID Number: NIST-SS26-03 Title: Rigging and Repair of Wind Tunnel Motor-Generator Set Response Date: April 22, 2026 The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial products/services that satisfy the Government’s anticipated needs. BACKGROUND The NIST Sensor Science Division (SSD) supports the US industrial competitiveness by advancing the next generation of SI-traceable measurements in dimensional metrology, thermodynamics, optical radiation, and fluid flow. The Fluid Metrology Group (FMG) within the SSD maintains standards for realizing gas flow, including air speed. The primary way the FMG provides SI traceability to US industry is by calibrating transfer airspeed measurement devices in the NIST wind tunnel. The NIST wind tunnel is a highly specialized facility originally built in the 1960s. Recently, the generator half of the motor-generator set in the power system failed and needs to be rebuilt. This current repair request is needed to restore the wind tunnel's power system to functional condition. Scope of Work: The Contractor shall provide services to repair an existing motor-generator set on the NIST wind tunnel power system. The system shall be restored to operating at full specifications on the nameplate of the machine. Currently, the generator on the set has failed. The brushes were used beyond their intended life and caused significant damage to the machine. Several brush housings have been damaged, and the commutator worn to the point that the mica filler stands higher than the metal contacts. Maker: Reliance Serial Number: 1UP893611T1-KT & 1XP893611A1-JT Model: 8002A-S & 5808S NIST property number: N/A Value: $500,000 (estimate) NIST is seeking information from sources that may be capable of providing a solution that will achieve the objectives described above, in addition to the following essential requirements: TECHNICAL REQUIREMENTS: Disconnect power and remove all fasteners, rig Generator out of NIST Building 230 Transport to repair facility Perform incoming electrical testing Remove 12 brush boxes, clean and repair. (The brushes boxes that are on the Generator are Obsolete) Disassemble and inspect, steam clean Armature and field frame and bake dry, test Shunt fields and interpoles, and test bearings and housings Lathe check armature for run out, turn and Undercut Commutator, Clean and repair Brush boxes, and balance armature Assemble generator with 2 new bearings, move to test stand and run @ full name plate voltage and speed Repair/manufacture/procure brush holders Clean and Stone Commutator, install brush boxes, seat brushes Prep and paint, make ready for transport Transport generator to NIST and rig Generator back onto base and Laser Align to Motor, re-connect power leads, stand by for startup Replace two new bearings in motor portion of the motor-generator set and perform electrical testing of the field and armature Replace new brushes in the main fan drive motor Standby to ensure successful startup of the motor-generator set.
