The swing motor (200) outputs reciprocating swing motion, and has a swing arm (204) that is mounted on the main frame (100) and is capable of rotating around a fulcrum. The wings (300) are installed on the swing arm (204) of the swing motor (200) and may form a reciprocating fanning motion under the drive of the swing arm (204). The described aircraft employs a swing motor whose control circuit generates alternating pulses having adjustable pulse widths, so that the moving direction of permanent magnets changes alternately, thus forming a reciprocating swing. The swing motor does not experience stalling, automatically reduces swing amplitude when resistance is high or swing frequency is high, responds quickly to input signals, may achieve swing of various frequency modes, and may more realistically immitate the swinging pattern of wings of flying creatures such as birds and insects, thereby enabling the aircraft to form more enriched flight modes.

Thus, in the process of the wings (20) repeatedly oscillating or vibrating, air flow is only able to flow from one side of the wings (20) to the other side of the wings (20), thereby acquiring lift for the aerial vehicle to fly. D: An electric cleaning brush for cleansing a surface of a biological body, comprising: an oscillating motor and a brush driven by the oscillating motor. The oscillating motor comprises a U-shaped yoke (100), four permanent magnets and an oscillating arm (400).
