Good Morning,
The ARC Team I mentor primarily uses Aerotech F size motors. Over the last two to three years they have accumulated a small inventory of unused motors.
Some of these unused motors could be between two to three years old and probably have seen temperatures between 30° and 90° F. The motors were probably stored stored most of the time in a conditioned space around 60°F but may have spent a winter in a unheated space where the outside temperatures could have dropped below 30°F. The motors were pretty protected while traveling but mostly lived in tackle boxes so they were banged around a bit. Humidity would have been fairly low.
The question is, does the age and the past storage practices of these motors effect their performance? Can the Team depend on these motors performing "just as good" as new motors they would buy this year?
The team does weigh each motor "to do something" before each launch but other than that do not know of any way to check for reliability or pre-launch performance.
Thank you in advance for your time, thoughts, and comments.
