Challenges
An automotive display supplier needed precise conveyor and positioning motion inside a low-temperature aging chamber. Standard steppers failed from lubricant hardening and condensation as temperatures dropped.
Solution
- Cryogenic-rated bearing lubrication and moisture-resistant winding insulation.
- Matched HD235 wide-temperature drivers with over-temperature protection.
- Reliable start-up after repeated thermal cycling.
Results
- Eliminated unplanned stops caused by drive failures in the cold chamber.
- Stable positioning accuracy maintained across the full temperature profile.
