1. An electromechanical flywheel comprising:
a motor-generator rotor surrounding a motor-generator stator; a flywheel mass configured to rotate with the motor-generator rotor; the flywheel mass and the motor-generator rotor located inside an evacuable housing; a gas removal train external to the evacuable housing; the train including a mechanical vacuum pump and a non-mechanical gas removal device; getter material and molecular sieve material in a casing of the non-mechanical gas removal device; the train operable to fluidly couple the casing and the evacuable housing for lowering the pressure in the evacuable housing; a pressure sensor configured to sense the pressure in the evacuable housing; and, the mechanical pump configured to operate intermittently in accordance with differences between a pressure sensed by the pressure sensor and a threshold vacuum pressure level. |
