Subject: High speed gas circulator with magnetic bearings
Does anyone have or know where I can turn for recent information on the reliability and performance of high speed gas circulators, variable speed controllers, and/or magnetic bearings and their control unit? The circulators are intended operate over a speed range of 7000 to 40000 rpm in a hydrogen loop and temperatures from ambient down to 20K. Any input is greatly appreciated.
