Challenges
An automated biobank needed motors that operate inside ultra-low temperature freezers for sample storage and retrieval. Electronics and lubricants fail long before metal parts do at these temperatures.
Solution
- Deep-cryogenic motor design qualified at −196 °C in liquid nitrogen tests on our self-developed low-temperature test platform.
- Driver electronics placed outside the cold zone; HF36 cryo-rated resolver inside.
- Condensation-safe construction for freezer door transitions.
Results
- Continuous operation in −150 °C storage environments.
- Sample integrity protected through fully automated, human-error-free handling.
