Development and Testing of a High Compact Stepper Motor Mechanism.

摘要

The Laboratory for Atmospheric and Space Physics (LASP) has developed for the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission an Imaging Ultraviolet Spectrometer (IUVS) instrument. A grating flip mechanism (GFM), inside the IUVS instrument, is based on a highly compact and innovative stepper motor solution to drive an optic in two precise, bi-stable positions. Rotation angle between positions was 90 . This paper discusses major design restrictions, unique design characteristics and lessons learned from the development up through environmental and performance testing.
