  • Apparatus for detecting angular displacement, system for controlling rotation angle of motor, gimbal, and aircraft
    Patent number: 10404143
    Abstract: The present invention relates to the field of motor detection, and in particular, to an apparatus for detecting an angular displacement, a system for controlling a rotation angle of a motor, a gimbal, and an aircraft. The apparatus for detecting the angular displacement provided the present invention includes a combined magnet, a Hall sensor, and a transmission component. The combined magnet includes a first magnet, a weak magnetic layer, and a second magnet that are sequentially stacked. Magnetic pole directions of the first magnet and the second magnet are opposite and parallel to the weak magnetic layer. The transmission component is connected to the combined magnet, and drives the combined magnet to rotate, or, the transmission component is connected to the Hall sensor, and drives the Hall sensor to rotate.
