ABSTRACT:
A protection system for electric motors in refrigerated environments, especially those environments cooled to very low temperatures, includes routing a cryogen coolant through the electric motor. A minimum flow of cryogen coolant is maintained through the motor to prevent ingress of moisture in the motor interior. The arrangement is especially useful with cryogenically cooled refrigeration systems, because the same cryogen coolant used to refrigerate the system can also be used to provide a purging flow of cryogen coolant gas through the electric motor.
