About this file
This Statement of Work (SOW) details the procurement of a Model 101 Micro Coil Winding Machine with MCS2 control for NASA's Goddard Space Flight Center. The specialized bench-top machine is designed to wind and bond ultra-fine wire (as small as 59 AWG) onto mandrels with precision, featuring two electronically synchronized servomotors, an advanced wire tensioning system, and a programmable hot air torch option. The machine will be used to automate the coil winding process for the Miniaturized Science fluxgate Magnetometer (MSM) in the Heliophysics Division.
The machine's technical specifications include a precise spindle design that allows rotation of small mandrels from both ends without wobble, a traverse wire guide system with ultrafine wire tensioning, and positioning resolution of 0.0001 inch/2.54 um. The place of performance is the Magnetic Facility at Goddard Space Flight Center, specifically in B21-Rm225 and Area 300. The period of performance begins in October 2025 and continues onwards, focusing on improving the efficiency of coil winding for scientific instrumentation.

STATEMENT OF WORK (Procurement of MCS Micro Coil Winding
Machine)
1. Objective/Requirements
This SOW accompanies a purchase request for the procurement of a new Model 101 Micro
Coil Winding Machine with an MCS2 control. The typical application of this machine is to wind and bond wire directly on a core that is rotated from both ends.
2. Characteristics, Scope, and Specs
The Model 101 is a special purpose built, bench top coil winding machine. It is designed to tension & wind ultra fine wire onto a mandrel.
The spindle design will hold very small tooling that would hold very small mandrels and rotate them from both ends. Therefore, there are two servomotors that are electronically synchronized to precisely rotate the same amount and speed. The (left side) headstock spindle motor is mounted in a gimbal that allows it to be critically positioned to match the (right side) tailstock spindle motor. This allows a mandrel to be driven at both ends without wobble. The tailstock moves left and right to either stretch or compress the winding mandrel (depending on tooling). A programmable regulated pressure is applied to a “no stiction” air cylinder to hold the mandrel in place. The regulated pressure assures firm grip without damage to fragile mandrels, The traverse wire guide system starts with an ultrafine wire tensioner that rotates the supply spool of wire. A sensor is used to detect the wire tension and rotate the spool to pay off the wire with constant tension. Ultrafine wire like 59 AWG can be continuously removed from the spool without breakage. The tensioned wire is then routed on pulleys to align with a special ultrafine wire finger guide. The finger guide is adjusted with “feeler gauges” to the thickness of the wire.
The wire passes through the finger guide as it is applied to the rotating mandrel. The finger guide is attached to the precision servomotor driven traverse to guide and layer the wire while winding.
The servomotor turns a precision fine pitch leadscrew for positioning in .0001 inch / 2.54 um resolution.
An optional programmable “hot air torch” is available to provide heat to bondable wire. The device has program selected airflow of both hot and cold air during the winding and cooling cycle.
3. Place of Performance
Goddard Space Flight Center, Magnetic Facility, or in B21-Rm225 and in Area 300.
4. Period of Performance
October 2025 and onwards. The procured machine will be utilized to automate the laborious coil winding process for the Miniaturized Science fluxgate Magnetometer
(MSM) of the Heliophysics Division, Code 670.
