Title:
GIMBAL AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/060123
Kind Code:
A1
Abstract:
A gimbal and an unmanned aerial vehicle. The gimbal specifically comprises: a support (10), which is used for carrying a camera device (20); an electric motor (11), which is used for driving the support (10) to rotate, and comprises a stator (111) and a rotor (112); an electronic speed controller, which is electrically connected to the electric motor (11), and is used for controlling the electric motor (11) to operate, wherein under the control of the electronic speed controller, the electric motor (11) is powered on and outputs power; and a magnetic gear assembly (12), which comprises a torque input end and a torque output end, the torque input end being mechanically coupled to the rotor (112), and the torque output end being mechanically coupled to the support (10), wherein the electric motor (11) drives the torque input end to rotate, and after rotation speed is changed via the magnetic gear assembly (12), the torque output end drives the support (10) to rotate, so as to change the attitude of the camera device (20). The electric motor (11) can realize the transmission of a relatively large torque in a relatively small space, and the precision of torque transmission is relatively high. Moreover, as the usage time is extended, relatively high transmission precision and relatively low transmission noise can also be achieved.
