A low-disturbance dual-gimbal flywheel based on a spatial parallel mechanism, comprising a parallel mechanism platform. The parallel mechanism platform is a spatial parallel mechanism that comprises N drive branches, a stationary base, and a movable platform, and has at least two rotational degrees of freedom; a wheel body and a rotor of a high-speed motor are mounted on a bearing; a stator of the high-speed motor and the bearing are mounted on the movable platform of the parallel mechanism platform; the parallel mechanism platform, the wheel body, the high-speed motor, and the bearing are mounted inside a housing by means of a stationary base interface of the parallel mechanism platform; a support lug outside the housing is connected to an external spacecraft deck; the housing envelopes the maximum movement range of the wheel body; the parallel mechanism platform controls movement of the movable platform by movement of the plurality of drive branches. According to the present invention, the ultra-light, ultra-static and ultra-agile effects of a spacecraft attitude control platform can be realized; the flywheel is particularly suitable for spacecraft such as small and medium-sized satellites which are rapidly developing today.
