Gearbox assembly joins the circus
One of Empire Magnetics' custom motor gearbox assemblies has made its way into show business as an unnoticed yet essential co-star in "O" by Cirque du Soleil at Bellagio in Las Vegas, Nevada.
These motors have been field-tested for reliable operation in temperatures as low as 20K, and can potentially operate at temperatures as low as 0K, but that is untested.
They are constructed with special dry lubrication and exotic chromium-nickel steel alloy components for compatible thermal expansion characteristics and reduced brittleness - highly important characteristics for motors that will be subjected to very cold temperatures.
Standard servomotors are typically rated for 0-100C operation, but Empire's Cryogenic Series motors vastly extend that operating range for applications such as superconductor research, observatory instrumentation (eg infra-red sensor testing), semen storage, and specialised research in physics and military application.
