A rotary solenoid used in the Dual Strong-Link Assembly (DSA) has a housing diameter of 0.67 inches, and overall length of approximately 1.37 inches. The rotor and housing each have four poles. When the coil is energized and the shaft is rotated, magnetic torque is produced which completes four nominally identical cycles during each revolution of the shaft. At zero and 90 degrees of shaft rotation, the poles are aligned and the rotor is stable. The mid-point between poles is unstable; any displacement produces a torque toward one of the stable points. A torque measurement is performed on each solenoid produced. The measurement technique used previously was labor intensive and required that analog torque plots be manually interpreted to determine compliance with the torque specification. This paper describes a robotically assisted torque measurement system that was developed and placed into production. This system reduces cycle time from approximately 6 minutes per part to a little more than 1 minute per part.
