  • Patent number: 10298848
    Abstract: The present invention discloses a motor, a gimbal including the motor and an aircraft including the gimbal. The motor includes a base, a rotation shaft, a stator assembly, a first bearing, a stator bearing and a rotor assembly that is used for driving an external member to rotate. The rotation shaft has a first end portion, a second end portion and a middle portion connecting the first end portion to the second end portion. The base is connected to the first end portion by using the first bearing. The rotor assembly is connected to the middle portion. The stator bearing, the rotor assembly and the first bearing are sequentially arranged along an axial direction of the rotation shaft. The stator assembly is connected to the rotation shaft by using the stator bearing.

  • Patent number: 10060576
    Abstract: Method, device, and apparatus for a gimbal parameter adjustment are provided. An exemplary method includes: controlling a supply of power to a motor upon detection of a gimbal parameter adjustment event, recording rotational angular velocity data of a gimbal axis controlled by the motor at respective time points, calculating angular acceleration data at the respective time points based on the rotational angular velocity data, determining a peak frequency within a predefined frequency band after performing a frequency conversion on the angular acceleration data, and configuring the peak frequency as a trap frequency of the motor to filter out a signal sending to the motor and having a frequency of the trap frequency.
