Title

Systems Design, Fabrication, And Testing Of A High-Speed Miniature Motor For Cryogenic Cooler

Abstract

The long-term storage of liquid hydrogen for space missions is of considerable interest to NASA. To this end, the Reverse Turbo-Brayton Cryocooler (RTBC) is considerably lighter than conventional designs and a potentially viable and attractive solution for NASA's long-term Zero-Boil-off (ZBO) hydrogen storage system for future space missions. We present the systems design, fabrication, and performance evaluation of the Permanent Magnet Synchronous Motor (PMSM) powering a cryocooler capable of removing 20W of heat at 18K with a COP of 0.005 and driven by two 2-kW permanent magnet synchronous motors operating at 200000rpm and at room temperature and 77 K. Structural, thermal, and rotordynamic aspects of system design are considered. Copyright © 2009 Dipjyoti Acharya et al.
