Abstract
The present invention provides a photographic assembly, including a pitch motor, a roll motor and a camera. A second rotor portion of the pitch motor is coupled to the third stator portion of the roll motor and a third rotor portion of the roll motor is coupled to the camera, so that a connection manner of the photographic assembly is a pitch-roll manner. When the roll motor is working, a displacement variation of the camera along a pitch axis is small. That is, a rotation interference phenomenon is weakened, so that a rotation space that needs to be reserved between the camera and the roll motor is correspondingly reduced. That is, distances between the centre of gravity of the camera and the motors are also decreased. Therefore, the photographic assembly becomes more compact at some portions, thereby achieving an objective that the volume, the weight, and the moment of inertia of the photographic assembly are reduced.
