FLYWHEEL SUPPORT MECHANISM FOR AXIAL-TYPE MOMENTUM WHEELS

Abstract

The invention relates to a flywheel support mechanism in a spherical momentum wheel used in satellite attitude control. The stator uses electrically engineered steel sheets [201] designed in an arc shape arranged to form a sphere containing the flywheel [1011]. The lifting rollers [401] are arranged symmetrically on the steel sheet frames [201] with a screw mechanism [404] and springs [403] for adjustment. They serve to lift the flywheel [101], create an air gap between the flywheel and the stator, reduce friction between them without consuming power, and also help to fix the rotor at the center of the spherical momentum wheel when not in operation, as well as ensure that it does not vibrate during satellite launch.
