Abstract

Techniques are disclosed for systems and methods for nested gimbal assemblies. A gimbal system may include a base, a yoke, and a gimbal assembly rotatably connecting the yoke to the base. The gimbal assembly may include a motor, a bearing, and a ferrofluid seal. The motor may be configured to rotate the yoke relative to the base about a rotational axis. The bearing may be seated within the base and permit rotation of the yoke relative to the base about the rotational axis. The ferrofluid seal may be positioned to seal an interface between the yoke and the base. The motor may be positioned within an inner diameter of the bearing. The bearing may be positioned within an inner diameter of the ferrofluid seal.
