Abstract
The invention belongs to the technical field of unmanned aerial vehicles, and provides a motor and duct integrated device, an unmanned aerial vehicle and a test method.The motor and duct integrated device comprises a duct, a rotating ring, a rotor wing and a rim motor; the rim motor is mounted in the duct, and a magnetic flux path is parallel to the axis of the duct; the multiple rotor wings are installed on the inner surface of the rotating ring and located on the inner side of the duct. The rotating ring is fixedly connected with the inner surface of a rotor of the rim motor. The rim motor is installed in the duct, and the magnetic flux path is parallel to the axis of the duct, so that the installation space of the system is reduced, the power density of the system is improved, and compared with a traditional radial magnetic flux motor, the weight and the size of the motor are reduced.
