The rotor assembly includes a rotating shaft 3131 and a rotor magnetic ring 3132. The upper surface of the front cover 2311 is connected to the bottom of the support arm 212. The control plate 22 is located above the front cover 2311. A connecting section extends downward from the center of the lower surface of the front cover 2311. The stator assembly 2312 is sleeved on the connecting part 3111. One end of the rotating shaft 3131 passes through the connecting part 3111 and is fixed to the front end cover 2311 and connected to the induction magnetic ring 232.

Furthermore, the height placed in the slot 221 can be adjusted according to the control method, thereby adjusting... By adjusting the distance between the motor assembly 23 and the end face of the motor body 231, the entire control board 22 can be moved without moving it, thus minimizing the overall height of the camera. It can be seen that, compared with traditional gimbal cameras, the gimbal camera 100 of this utility model no longer needs to leave the height of the entire magnetoelectric sensor 241 in the height direction between the motor assembly 23 and the control board 22, which can effectively reduce the overall height of the camera. Furthermore, the distance between the control board 22 and the motor assembly 23 can be adjusted by adjusting the placement height of the magnetoelectric sensor 241 in the placement slot 221, thereby further reducing the overall height of the camera and making the overall size of the gimbal camera 100 smaller.
