| description | The present invention provides a compact control moment gyroscope that enables extension of service life of gimbal bearings, and that also enables increases in disturbances that act on a spacecraft as a result of shaft vibration of a rotor to be suppressed. The control moment gyroscope includes: an inner gimbal (9); a rotor (1) that is held by the inner gimbal (9) so as to be rotatable around a spin axis (5); a spin motor (3) that is disposed on the inner gimbal (9), and that rotates the rotor (1) around the spin axis (5); a stator (10) that holds the inner gimbal (9) so as to be rotatable around a gimbal axis (7) that is perpendicular to the spin axis (5); gimbal bearings (6) that are disposed between the inner gimbal (9) and the stator (10) so as to face each other from opposite sides of a plane that is perpendicular to the gimbal axis (7) and that includes the spin axis (5), so as to be in contact with the plane in question, or so as to include the plane in question; and a torque module (8) that is disposed on the stator (10), and that rotates the inner gimbal (9) around the gimbal axis (7). |
