phySPACE stepper motors; 2-Phase-hybrid; 19 56 mm 
Stepper Motor for SPACE applications 
The phySPACE Stepper Motor Series is the result of more than 25 years of space heritage and over 300 phytron motors in space. The phySPACE is built to resist vibrations, radiation and high temperature. Due to the ECSS conform materials the phySPACE fulfills the high requirements for usage in ultra high vacuum, while providing an optimum of power consumption, thermal dissipation, stray magnetic flux, high precision positioning long life and extreme robustness.
