Brushless Servo Motors are suited for cold environments.

Press Release Summary:



Size 23 Cryogenic Series motors with resolver feedback, engineered for motion control applications, operate reliably in temperatures down to 20°K and have potential to operate at temperatures as low as 0°K. They are constructed with dry lubrication and chromium-nickel steel alloy components for compatible thermal expansion characteristics and reduced brittleness. Applications include research, observatory instrumentation, and semen storage.

New Cryogenic Brushless Servo Motors with Resolver Feedback


Rated for operation in extreme cold temperatures

ROHNERT PARK, CA -- Empire Magnetics introduces Cryogenic Series brushless servo motors with resolver feedback. Available in standard size 23 (consult factory for additional sizes), these motors are specifically engineered for motion control applications that require reliable motor operation in extremely cold conditions.

These motors have been field-tested for reliable operation in temperatures as low as 20 Kelvins, and can potentially operate at temperatures as low as 0 Kelvins, 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 servo motors are typically rated for 0° - 100° C operation, but Empire's Cryogenic Motors vastly extend that operating range for applications such as superconductor research, observatory instrumentation (e.g. infrared sensor testing), semen storage, and specialized research in physics and military application.
