BEI Kimco's VCA goes to asteroids

October 25, 2013 -  A BEI Kimco Magnetics' custom Moving Magnet Voice Coil Actuator (VCA) meets the requirements for the Michelson interferometer moving mirror application on the Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-Rex) spacecraft. The OSIRIS-Rex will launch in 2016, rendezvous with the Asteroid Bennu in 2018 and return samples to Earth in 2023. Redundant technology, low-outgassing and high precision for exact motion control positioning were all key requirements to the actuator design.
 
For this space exploration, BEI Kimco's custom moving magnet VCA is attached to, and positions the Moving Mirror assembly of the OTES Infrared Spectrometer (a derivative of the Mars Exploration Rover Mini-TES and Mars Global Surveyor TES flight spectrometers).   As the spacecraft approaches the asteroid, the spectrometer scans the surface so that the material can be analyzed for different parameters. The mission will be a vital part of NASA's plans to find, study, capture and relocate an asteroid for exploration by astronauts.
 
The BEI Kimco VCA is uniquely manufactured to custom requirements for high reliability and fail safe operation. Critical to the actuator design was meeting all performance requirements while staying within the size, weight and power limits. This was achieved in a housing measuringapproximately 2" in diameter by 3" long.
 
To meet the requirements for near zero emissions, BEI Kimco developed the actuator without adhesives or inks and manufactured and assembled all parts by mechanical means utilizing clean manufacturing processes, thereby eliminating substances that could cause outgassing. High energy Neodymium Iron Boron (NeFeB) magnets were incorporated to provide superior operating efficiencies.
 
"BEI Kimco specializes in meeting unique customer demands," explains Jim McNamara, Senior Applications Engineer. "BEI Kimco has participated in many space exploration programs where highly customized low outgassing designs with high reliability (including redundancy) strict quality control, and cleanliness were all needed."
